Overview

What this SWMS covers

Synthetic grass installation transforms outdoor spaces into low-maintenance, year-round usable surfaces suitable for sports, recreation, landscaping, and commercial applications. Modern synthetic turf products simulate natural grass appearance and performance characteristics using synthetic fibres (typically polyethylene, polypropylene, or nylon) tufted into backing material with integral or separate shock-absorbing pads. Installation quality directly affects surface performance, drainage, longevity, and user safety particularly for sports applications where surface characteristics affect ball behaviour, player traction, and injury risk from falls or sliding contact. Synthetic grass products vary significantly across applications. Residential landscape products feature shorter pile heights (20-35mm), softer fibres prioritising appearance and feel, simpler backing without shock pads, and typically no infill requirements. Sports field products have taller pile heights (40-65mm), more durable fibres withstanding cleated footwear and intensive use, engineered shock pad systems meeting sports surface standards, and infill requirements using sand and rubber granules achieving specified ball bounce and player impact characteristics. Playground surfaces require additional safety features meeting AS 4422 impact attenuation standards. Each product type requires different installation techniques, base preparations, and finishing procedures affecting equipment selection, material handling, and installation duration. Base preparation is critical for successful synthetic grass installation and long-term performance. For residential installations, typical base consists of compacted crushed rock or decomposed granite (75-100mm depth) achieving stable, level surface with adequate drainage gradients. Sports field bases require more substantial construction including 150-300mm compacted aggregate base, precise laser levelling achieving specified gradients and tolerances, and drainage systems managing surface water and subsurface moisture. Base must achieve specified compaction (typically 95-98% maximum dry density) preventing future settlement causing surface undulations or drainage problems. Inadequate base preparation is the primary cause of installation failures requiring costly remedial work including complete surface removal and base reconstruction. Installation sequencing involves base preparation and verification, geotextile installation preventing contamination and aiding drainage, shock pad placement for sports surfaces, synthetic grass roll placement and layout with pile direction consideration, seam cutting and joining using specialized equipment and adhesives, perimeter securing using nails, stakes, or adhesives, infill spreading and grooming for sports surfaces, and final inspection verifying quality standards. Large projects including sports fields require teams of 4-8 installers working 5-10 days depending on area and complexity. Residential installations typically require 2-3 installers completing work in 1-3 days for average residential lawns. Installation scheduling considers weather particularly rain affecting adhesive curing and temperature extremes affecting material handling and adhesive working time.

Why this SWMS matters

Synthetic grass installation safety is critical due to multiple hazards including chemical exposures, manual handling demands, and heat-related illnesses. Adhesives used for seam joining contain volatile organic compounds (VOCs), polyurethane chemicals, and solvents causing respiratory irritation, dizziness, and potential long-term health effects from chronic exposure. Installers working in poorly ventilated enclosed spaces or during hot weather when vapour generation is highest experience dangerous exposure levels. Without adequate ventilation and respiratory protection, installers develop acute symptoms including headaches, nausea, and breathing difficulty, whilst long-term exposure contributes to chronic respiratory disease and potential neurological effects from solvent exposure. Manual handling injuries are endemic in synthetic grass installation due to heavy roll weights and repetitive handling activities. Residential synthetic grass rolls weigh 100-200kg for typical rolls 2-4 metres wide and 10-20 metres long. Sports field rolls can exceed 400kg particularly when including integrated shock pad systems. Installers must unload rolls from delivery vehicles, transport across sites using trolleys or manual carrying for shorter distances, unroll and position accurately requiring sustained lifting and pulling, and tension turf during seam joining and perimeter fixing. Back injuries, shoulder strains, knee injuries from sustained kneeling during seam work, and hand injuries from gripping techniques cause lost time injuries affecting installers' long-term work capacity. Without mechanical handling equipment, proper techniques, and task rotation, musculoskeletal injuries are inevitable. Heat stress during summer installation work combines multiple risk factors including outdoor exposure to direct sunlight and radiant heat from dark turf surfaces, strenuous physical work generating metabolic heat, inadequate hydration particularly when working on remote sports field sites distant from facilities, and work scheduling pressure meeting project deadlines regardless of weather conditions. Synthetic grass surface temperatures can exceed 60°C in summer sunlight with installers working directly on these hot surfaces during placement and finishing. Heat stress progresses from heat exhaustion causing reduced work capacity and coordination, to potentially fatal heat stroke requiring emergency medical intervention. Recent Australian summers with extended heatwave periods dramatically increase heat stress risk particularly in inland and northern locations. Quality control during installation affects long-term product performance and client satisfaction. Poor seam joining creating visible join lines or weak bonds failing under use causes client complaints and warranty claims. Inadequate infill depth or distribution affecting sports surface performance requires costly remediation. Base settlement causing surface undulations affects drainage, appearance, and sports ball behaviour. These quality failures result from rushed installation, inadequate training, poor weather management, or cost-cutting on materials and base preparation. The SWMS ensures quality procedures are integrated with safety management protecting both workers and installation quality outcomes.

Hazard identification

Surface the critical risks tied to this work scope and communicate them to every worker.

Risk register

Chemical Exposure from Turf Adhesives and Solvents

high

Seam joining and perimeter fixing uses two-component polyurethane adhesives containing isocyanates, volatile organic compounds (VOCs), and organic solvents. These chemicals release vapours during mixing, application, and curing causing acute respiratory irritation, dizziness, headaches, and nausea particularly in poorly ventilated conditions or hot weather when vapour generation accelerates. Skin contact causes dermatitis and potential chemical sensitisation where future exposures trigger severe allergic reactions. Enclosed installation areas including under-building spaces or indoor sports facilities concentrate vapours creating dangerous exposure levels. Installers may develop chronic health effects from repeated exposures over years of installation work including respiratory disease, liver and kidney effects from solvent exposure, and potential carcinogenic effects from certain chemical components. Flash point of some adhesive components creates fire hazards if ignition sources including sparks, cigarettes, or hot work occur near application areas.

Consequence: Acute respiratory distress requiring emergency medical treatment, chemical sensitisation causing severe reactions from future exposures potentially ending careers, chronic respiratory disease from repeated exposures, dermatitis and skin sensitisation requiring ongoing medical treatment, neurological effects from chronic solvent exposure, and fire risk from adhesive vapour ignition.

Manual Handling of Heavy Synthetic Grass Rolls

high

Synthetic grass rolls for typical residential installations weigh 100-200kg, whilst sports field rolls can exceed 400kg particularly when including integrated shock pad backing. Installers must manually handle rolls during unloading from delivery vehicles, transport across installation sites, position precisely during layout, lift and tension during seaming operations, and reposition if initial placement is incorrect. Roll handling requires awkward grips on cylindrical objects without proper handles, sustained lifting during unrolling operations, and working in bent or kneeling postures during placement and seaming. Team lifts with 2-4 people are standard but coordination failures or uneven load sharing increases individual strain. Dropping rolls causes foot and leg crush injuries. Repeated roll handling over 8-10 hour installation days causes cumulative musculoskeletal strain affecting backs, shoulders, knees, and hands.

Consequence: Acute lower back injuries causing immediate work cessation and potential long-term disability, shoulder rotator cuff tears requiring surgical repair, knee cartilage damage from sustained kneeling work, hand and wrist strain injuries, crushed feet or legs from dropped rolls causing fractures and soft tissue trauma, and chronic musculoskeletal disorders affecting long-term work capacity.

Heat Stress from Working on Hot Synthetic Surfaces

high

Synthetic grass surfaces absorb solar radiation heating to temperatures 30-50°C above ambient temperature, with surface temperatures exceeding 60°C common during summer installation work. Installers work directly on these hot surfaces during roll placement, seam joining, and infill spreading, experiencing radiant heat load in addition to direct solar exposure and metabolic heat from physical work. Kneeling or lying on hot turf surfaces during seam joining causes contact heat exposure burning exposed skin. Dark-coloured infill materials (rubber granules) reach extreme temperatures creating additional heat sources. Inadequate hydration particularly on large remote sports field sites without nearby facilities compounds heat stress. Working in chemical-resistant PPE during adhesive application prevents heat dissipation dramatically accelerating heat stress development. Heat stress symptoms including dizziness, nausea, and reduced coordination increase other injury risks by affecting judgment and physical capability.

Consequence: Heat exhaustion causing collapse requiring emergency cooling and medical assessment, heat stroke requiring emergency hospitalisation with potential fatal outcome if treatment delayed, contact burns from sustained contact with hot turf surfaces, dehydration affecting physical and cognitive performance, and increased risk of other injuries from reduced coordination and judgment during heat-affected work.

Cutting Tool Lacerations During Turf Trimming and Seam Preparation

medium

Synthetic grass installation requires extensive cutting using sharp utility knives, hooked trimming blades, and powered cutting tools for turf trimming to boundaries, seam edge preparation, and obstacle penetrations. Installers must cut through tough synthetic fibres and backing material requiring sharp blades and substantial force. Blades can slip during cutting particularly when encountering backing seams or adhesive residues causing hand and finger lacerations. Installers often work in awkward positions during cutting including kneeling, bent over, or reaching into confined spaces reducing cutting control. Blunt blades requiring excessive force increase slip risk. Multiple installers working simultaneously create inadvertent contact hazards when passing materials or moving around work areas with exposed blades. Improperly stored cutting tools in pockets or tool belts present laceration risks during bending or reaching movements. Night work or low-light conditions increase cutting hazards by reducing visibility of cutting lines and blade position.

Consequence: Deep lacerations requiring emergency medical treatment and suturing, severed tendons or nerves affecting permanent hand function, arterial cuts causing significant blood loss requiring emergency response, puncture wounds from blade tips, infections from contaminated cutting tools, and secondary injuries from loss of balance after cutting injuries.

Knee Injuries from Sustained Kneeling During Seam Work

medium

Seam joining requires installers to work on hands and knees for extended periods (2-4 hours continuously) during seam cutting, tape placement, adhesive application, and turf positioning. Hard surfaces including compacted aggregate bases or concrete provide no cushioning causing direct pressure on knee joints and bursae. Repetitive sliding and pivoting movements during seam alignment create shear forces on knee tissues. Hot surface temperatures during summer work add heat stress to mechanical loading. Inadequate knee pads or failure to use knee pads due to discomfort increases direct tissue damage. Installers may resist taking breaks during critical seaming operations (whilst adhesive working time is limited) prolonging kneeling periods beyond tolerable durations. Cumulative damage over months to years of installation work causes chronic knee pathology including bursitis, cartilage degeneration, and ligament strain requiring ongoing medical treatment and potentially ending careers.

Consequence: Acute bursitis causing immediate knee pain and swelling requiring medical treatment and time off work, chronic knee pain from cartilage damage requiring ongoing pain management, arthritis development in knee joints from cumulative damage, ligament and tendon strain affecting knee stability, and potential need for surgical intervention including arthroscopy or eventual knee replacement.

Infill Dust Inhalation During Spreading and Grooming

medium

Sports surface installation requires spreading rubber infill granules (typically 5-15 tonnes for full-size fields) using mechanical spreaders or manual broadcasting. This process generates substantial dust particularly from fine particles in infill materials and when working in dry, windy conditions. Rubber dust contains various compounds from tyre recycling including heavy metals, volatile organic compounds, and potential carcinogens. Sand infill generates silica-containing dust presenting long-term lung disease risks from chronic exposure. Power brushing during grooming creates highest dust generation launching fine particles airborne. Installers working directly behind spreading equipment or power brooms experience highest exposure. Wind disperses dust across entire work area affecting multiple workers. Dust adheres to skin, clothing, and equipment requiring careful cleanup to prevent continued exposure after work completion. Some infill products use antimicrobial treatments or coatings introducing additional chemical exposures during dust inhalation.

Consequence: Acute respiratory irritation causing coughing and breathing difficulty during work, chronic respiratory effects from repeated dust exposure over multiple projects, potential heavy metal absorption from contaminated rubber dust, silicosis risk from sand infill dust containing crystalline silica, eye irritation from dust contact, and unknown long-term health effects from novel infill material exposures.

Implementation guide

Mechanical Handling Equipment and Team Lift Protocols

Elimination

Eliminate manual carrying of synthetic grass rolls by using mechanical handling equipment including forklifts for unloading and positioning large rolls, all-terrain forklifts or telehandlers for sports field work across uncompacted bases, roll dispensers or unrolling equipment allowing controlled roll deployment without manual lifting, and motorised turf buggies for transporting materials across large sites. Implement mandatory team lift protocols requiring minimum 4-person lifts for rolls exceeding 150kg, with clear role assignment and communication during lifts. Position delivery vehicles close to installation areas minimising carry distances. This elimination approach removes primary cause of musculoskeletal injuries by eliminating heavy manual handling where mechanically feasible.

Implementation

1. Engage forklift or all-terrain forklift for unloading delivery vehicles and positioning rolls at installation starting points 2. Verify forklift operator holds current licence appropriate to forklift type being used 3. Use roll dispensing equipment allowing horizontal unrolling rather than lifting and manually deploying rolls 4. For large sports field projects, use motorised turf buggies or tracked vehicles transporting rolls across field rather than manual carrying 5. Implement mandatory 4-person lift protocol for residential rolls exceeding 150kg marking rolls clearly with weight and lift requirements 6. Assign lift coordinator calling lift initiation and directing team movements during coordinated lifts 7. Position delivery drop-off points at multiple locations around large sites reducing carry distances to maximum 20 metres 8. Use roll carts or dollies with pneumatic tyres for moving rolls across rough ground where forklifts cannot access 9. Schedule adequate labour for project - never attempt installation with insufficient team members forcing unsafe handling 10. Brief team on hand signals and communication during lifts particularly important in noisy environments

Respiratory Protection and Ventilation for Adhesive Work

Personal Protective Equipment

Provide respirators with organic vapour cartridges rated for isocyanate service (per AS/NZS 1716) for all workers involved in adhesive mixing, application, and seam joining operations. For enclosed installation spaces including undercover areas or indoor sports facilities, provide supplied air respirators or powered air purifying respirators (PAPR) offering higher protection levels. Implement forced ventilation using portable fans and open doors/windows during adhesive work. Schedule adhesive work during cooler morning periods when vapour generation is reduced and worker tolerance for respirator wear is higher. Conduct work in well-ventilated outdoor areas where feasible. This PPE-focused control prevents respiratory exposure when engineering elimination of adhesive use is not feasible.

Implementation

1. Provide half-face or full-face respirators with combined organic vapour and P2 particulate cartridges for all seaming crew 2. Conduct fit testing for each worker before first use and annually thereafter verifying adequate seal 3. For indoor or enclosed installations, provide PAPR units with organic vapour capability and P3 filters 4. Position portable fans creating airflow across work area directing vapours away from worker breathing zones 5. Open all accessible doors and windows in enclosed spaces before commencing adhesive work 6. Schedule seam joining work for morning periods (before 10am) when temperatures are lower reducing vapour generation 7. Implement work/rest cycles of 45 minutes work and 15 minutes rest when wearing respirators in hot conditions 8. Provide clean storage for respirators between uses preventing contamination and damage 9. Maintain respirator cleaning and disinfection procedures after each use preventing skin reactions from contaminated face seals 10. Replace organic vapour cartridges after 8 hours use or if chemical odours become noticeable through cartridge indicating saturation

Heat Stress Management and Work Scheduling

Administrative Control

Implement comprehensive heat stress management including work scheduling modifications during hot weather, mandatory hydration breaks, shaded rest areas, and heat stress monitoring. Start work at 6am during summer months completing physical tasks before peak temperatures. Schedule adhesive work for cooler periods. Provide electrolyte drinks beyond plain water replacing salts lost through sweating. Brief workers on heat stress symptom recognition. Monitor weather forecasts ceasing work when forecast temperatures exceed 35°C particularly if high humidity is also present. This administrative control reduces heat stress risk through work modification and environmental management rather than relying solely on PPE.

Implementation

1. During summer months (November-March), start work at 6am completing physically demanding tasks before 11am 2. Monitor Bureau of Meteorology forecasts and local temperature readings adjusting schedules based on predicted conditions 3. Implement mandatory 10-minute breaks every 30 minutes of work when temperatures exceed 30°C 4. Establish shaded rest area using marquee or existing structures providing escape from direct sun exposure 5. Provide iced water and electrolyte drinks in coolers maintaining continuous availability throughout workday 6. Brief workers each morning on heat stress symptoms including headache, dizziness, nausea, and confusion 7. Assign supervisor to monitor worker behaviour for heat stress signs including reduced work rate, irritability, or unsteady movement 8. Provide cooling vests or neck cooling towels for workers conducting sustained physical work in extreme heat 9. Cease outdoor work entirely if forecast maximum temperature exceeds 38°C or if heat stress symptoms develop in any worker 10. Reschedule work to evening periods (after 5pm) during extreme heat events when possible reducing temperature exposure

Cutting Tool Safety and Sharp Blade Management

Administrative Control

Standardise on retractable utility knives with automatic blade retraction when pressure releases eliminating fixed-blade knives from sites. Provide designated cutting stations with stable work surfaces rather than cutting on unstable or awkward surfaces. Maintain sharp blade inventory replacing blunt blades immediately rather than forcing cuts with dull blades. Implement blade disposal procedures using puncture-resistant sharps containers. Train workers in correct cutting techniques including cutting away from body, supporting material properly, and using appropriate force. Ensure adequate lighting at all cutting locations particularly during early morning or late afternoon work. This administrative approach reduces cutting injuries through equipment selection and procedural controls.

Implementation

1. Supply retractable utility knives with automatic blade retraction as standard equipment to all installers 2. Provide hooked trimming blades with guarded handles for seam edge cutting operations 3. Establish cutting station at worksite perimeter with stable bench or board providing proper cutting surface 4. Maintain blade replacement stock ensuring immediate replacement of dull blades without work delays 5. Provide puncture-resistant sharps containers at cutting stations for safe blade disposal 6. Train workers to inspect blades before each cut replacing immediately if nicked, bent, or dull 7. Implement cutting away from body rule with blade travel direction always away from non-knife hand 8. Require stable material support during cutting - never cut material held in air or on unstable surfaces 9. Provide adequate lighting at all cutting locations using portable lights if necessary during low-light periods 10. Store cutting tools in designated tool pouches or on benches - never in pockets where blades may deploy during movement

Knee Protection and Task Rotation During Seam Work

Engineering Control

Provide premium knee pads rated Type 2 per AS/NZS 4503 with maximum padding thickness and moisture-resistant covers for all workers conducting seam work. Use foam kneeling mats or padded boards beneath knee pads providing additional cushioning particularly on hard aggregate bases. Implement task rotation scheduling workers in 90-minute shifts for seaming work alternating with standing tasks including roll positioning, material delivery, or infill spreading. This combination of engineering equipment and administrative scheduling reduces cumulative knee loading preventing chronic injury development.

Implementation

1. Provide premium knee pads with maximum thickness padding (minimum 25mm) rated Type 2 per AS/NZS 4503 2. Supply foam kneeling mats or cushioned boards for placement beneath workers during extended seaming operations 3. Fit knee pads individually to each worker ensuring correct strap tension and pad positioning over knee joint 4. Implement 90-minute maximum continuous kneeling periods followed by minimum 30-minute break from kneeling postures 5. Rotate workers between seaming crew and standing tasks including roll handling, material delivery, or infill work 6. Schedule adequate workforce enabling rotation without delaying critical adhesive application timing 7. Replace knee pads when padding compresses below 15mm thickness as compressed pads lose protective effectiveness 8. Brief workers on importance of wearing knee pads consistently - pad effectiveness requires continuous use not intermittent 9. Allow workers to adjust work positions during seaming including periodic standing to stretch and restore circulation 10. For all-day seaming work on large fields, increase rotation frequency to 60-minute shifts providing more frequent position changes

Dust Suppression and Respiratory Protection for Infill Work

Engineering Control

Use water spray suppression during infill spreading operations wetting infill materials and work surfaces to minimise airborne dust generation. Position infill spreading equipment to work with prevailing winds placing dust downwind rather than toward worker positions. Provide P2 respirators (minimum) for workers conducting infill spreading and grooming operations particularly when working in dusty conditions or with materials containing silica sand. Schedule infill work during higher humidity conditions (morning or late afternoon) when natural dust suppression from moisture is greatest. This engineering dust control combined with respiratory protection prevents dust inhalation and associated health effects.

Implementation

1. Use water spray equipment wetting infill materials before spreading reducing dust generation at source 2. Adjust spreader equipment to release infill close to surface rather than broadcasting from height minimising dust release 3. Position spreader operation to work with prevailing wind placing operators upwind of dust generation 4. Provide P2 respirators (minimum) rated to AS/NZS 1716 for all workers conducting infill spreading and power grooming 5. Use P3 respirators when spreading sand infill containing crystalline silica providing higher filtration efficiency 6. Fit respirators correctly to each worker conducting fit checks before use to verify adequate seal 7. Schedule infill work for morning hours when humidity is typically higher providing natural dust suppression 8. Cease infill spreading during high wind conditions (exceeding 25 km/h) when dust control is ineffective 9. Clean equipment and work areas using wet methods or HEAP vacuum collection never using compressed air blowing which disperses dust 10. Brief workers on correct respirator donning, wear, and maintenance procedures ensuring consistent protection

Step-by-step work procedure

Give supervisors and crews a clear, auditable sequence for the task.

Field ready

Base Preparation Verification and Geotextile Installation

Verify base preparation meets specification requirements before commencing synthetic grass installation. Check base surface is uniformly compacted using plate compactor test or density testing achieving minimum 95% maximum dry density ratio. Surface should be firm with no soft spots or excessive movement under foot traffic. Use laser level or string lines verifying surface gradients match design specifications - typically 1:100 minimum gradient for drainage but may vary based on design. Check surface level tolerance using straightedge and measuring from multiple datum points - typically ±5mm for residential installations and ±3mm for sports surfaces. Identify and address any defects including soft areas, depressions, or incorrect gradients before proceeding as correction after turf installation is impractical. Install geotextile fabric if specified, rolling fabric across entire installation area with 300mm overlaps at joins. Secure geotextile edges using 150mm steel pins at 1-metre spacing or fold edges into perimeter trenches. Cut fabric accurately around obstacles, drains, or service access points. For sports fields, verify shock pad installation is complete before synthetic grass placement, checking shock pad is properly bonded to base, has no gaps or overlaps at joins, and achieves specified thickness throughout installation area.

Safety considerations

Verify base is adequately stable before driving equipment across surface - soft or inadequately compacted bases may not support installation vehicle weights. Ensure proper lifting techniques when handling geotextile rolls typically weighing 20-40kg. Watch for trip hazards from loose fabric edges or pins protruding above surface. Wear sun protection during outdoor base work as installation typically occurs in exposed areas without natural shade. Maintain hydration particularly during summer base verification work.

Synthetic Grass Roll Placement and Layout

Plan roll layout before unrolling to minimise waste and optimise seam locations. For rectangular areas, position seams parallel to longest dimension reducing total seam length. Avoid seams in high-wear areas or directly in front of goals on sports fields where possible. Ensure pile direction is consistent across all rolls - pile should lean toward primary viewing direction or along field length for sports applications. Use forklift or team lift (minimum 4 people for residential rolls exceeding 150kg) positioning first roll at installation starting point. Carefully unroll synthetic grass checking pile direction as unrolling proceeds. If pile direction is incorrect, stop immediately and re-roll for correct orientation - correcting after installation is impractical. Position roll allowing 50-100mm excess material extending beyond final boundaries for trimming. Place subsequent rolls alongside first roll ensuring pile direction matches and allowing slight overlap (5-10mm) for subsequent seam cutting. Continue roll placement systematically across installation area. For areas requiring multiple roll widths, minimise cuts and joins where possible. Allow rolls to relax for 2-4 hours in warm conditions before final positioning particularly important for rolls that have been stored in cool conditions or were tightly wound.

Safety considerations

Always use mechanical handling or minimum 4-person team lifts for rolls exceeding 150kg. Assign lift coordinator calling lift initiation and directing movements. Maintain clear communication during lifts using agreed signals particularly in noisy environments. Never attempt to catch falling rolls - step away and let roll drop rather than risking crush injuries. Watch footing when walking on geotextile which can be slippery particularly if damp. Ensure adequate spacing between workers during roll unrolling preventing accidental contact with rolls under tension.

Seam Cutting and Edge Preparation

Position rolls with 5-10mm overlap at seam locations. Ensure both roll edges are flat without ripples or waves affecting seam quality. Use sharp utility knife with hooked blade cutting through both turf layers simultaneously creating perfectly matched edges. Cut along manufacturer stitch line if present, or approximately 10mm from outer edge removing non-tufted backing material. Apply firm, steady pressure maintaining straight cutting line along entire seam length. For long seams on sports fields, use chalk line marking cutting line before commencing ensuring straight seam. Pull cut edges apart inspecting cut quality - backing should show clean cut without ragged edges or incompletely cut fibres. Trim any loose fibres or backing material preventing interference with seam bonding. For perimeter edges, position turf allowing 50mm excess extending beyond final boundary. Mark final edge position using chalk line then trim excess using sharp utility knife. Cut slowly and carefully at boundaries ensuring accurate edge placement - recutting short edges is not possible requiring patch installation if cut too short. For obstacle penetrations including drains, service access points, or posts, make diagonal relief cuts from edge toward obstacle allowing turf to lay flat around obstacle. Mark final cut line around obstacle then trim accurately.

Safety considerations

Use sharp blades for all cutting - dull blades require excessive force increasing slip risk. Cut away from body with blade travel direction away from non-knife hand supporting material. Kneel on stable surfaces using knee pads throughout cutting operations. Work in well-lit areas ensuring clear visibility of cutting line and blade position. Store cutting tools safely on benches rather than in pockets when not in use. Take breaks from sustained kneeling every 90 minutes preventing cumulative knee strain. Wear cut-resistant gloves on non-knife hand supporting material during cutting.

Seam Joining Using Adhesive Tape System

Fold back turf edges exposing base surface along entire seam length. Clean base surface removing any debris or loose material that could prevent tape adhesion. Position seam tape centered beneath seam gap with adhesive side facing upward. For outdoor installations use exterior-grade joining tape typically black geotextile material. Ensure tape lies flat without wrinkles or air pockets. Open two-component polyurethane adhesive mixing components according to manufacturer instructions typically 1:1 ratio by weight or volume. Mix thoroughly using paddle mixer achieving complete colour consistency indicating proper mixing. Pot life of mixed adhesive is typically 15-30 minutes depending on temperature - work within this time completing seam before adhesive becomes unworkable. Apply mixed adhesive to seam tape using notched trowel or plastic spreader achieving complete coverage across tape width. Use appropriate coverage rate per manufacturer specifications typically 400-600 grams per linear metre. Fold first turf edge onto adhesive tape ensuring backing contacts adhesive completely and pile direction is correct. Apply weight or use roller pressing backing firmly into adhesive. Fold second turf edge onto tape bringing cut edges together with minimal gap (less than 2mm). Use roller or hand pressure ensuring complete contact throughout seam length. Work methodically along seam checking alignment and bonding as proceeding. Do not walk on seam for minimum 4 hours allowing adhesive to cure. For sports fields, weight seam with sandbags or other heavy objects maintaining pressure during initial cure period.

Safety considerations

CRITICAL: Wear organic vapour respirators throughout all adhesive work from mixing through seam completion. Ensure respirator has correct cartridge type and adequate fit. Work in well-ventilated areas positioning portable fans if necessary. Wear chemical-resistant nitrile gloves during all adhesive handling preventing skin contact. Avoid skin contact with mixed adhesive - if contact occurs, clean immediately with appropriate solvent then wash with soap and water. Position body to work from side rather than over seam reducing direct vapour inhalation. Take breaks from adhesive work every 45 minutes when wearing respirators in hot conditions. Never eat, drink, or smoke during adhesive work preventing hand-to-mouth chemical transfer.

Perimeter Securing and Edge Fixing

Secure synthetic grass perimeter preventing edge lift and movement during use. For concrete or paved perimeters, use polyurethane adhesive applying continuous bead along edge then weighting turf edge during cure period. For soil perimeters in residential installations, use 150mm galvanised landscape nails or fixing pins at 150-300mm spacing along entire perimeter. Drive nails through turf backing at slight angle preventing nail heads lifting above surface. Ensure nails penetrate minimum 100mm into firm soil beneath providing adequate anchorage. For sports field perimeters, excavate perimeter trench 100mm deep and 150mm wide, fold turf edge into trench, then backfill with compacted soil or concrete securing edge permanently. This trench method provides most secure fixing for high-use applications. Where turf abuts walls or structures, apply adhesive bead between turf edge and structure, or use mechanical fixing with appropriate fasteners. Ensure perimeter is completely secured before proceeding to infill application or final finishing. Walk entire perimeter checking for any loose areas requiring additional fixing. Trim any fibers extending beyond edge achieving neat finished appearance.

Safety considerations

When using adhesive for perimeter fixing, maintain respiratory protection throughout application period. Position body to minimise bending strain during perimeter work - use kneeling pads or sitting positions rather than sustained bending from waist. Watch for hammer rebound when driving nails in hard soils - use appropriate force preventing excessive rebound striking operator. Verify mechanical fixings do not penetrate underground services before commencing fixing particularly near buildings where service entries are likely. Wear safety glasses during nail driving operations protecting against flying fragments if nails strike rocks or hard objects.

Infill Application for Sports Surfaces

For sports field installations, apply infill materials achieving specified depth and distribution across playing surface. Typical infill consists of silica sand base layer (typically 5-10kg per square metre) and rubber granules top layer (typically 5-15kg per square metre) though specifications vary by product and performance requirements. Use mechanical spreader for large fields achieving consistent distribution, or manual spreading using wheelbarrows and spreaders for smaller areas. Apply sand infill first distributing evenly across surface. Use drop spreader or broadcast spreader walking systematic patterns ensuring complete coverage. Use power broom or drag brush working across surface in multiple directions to work sand into turf pile and settle to backing level. Measure infill depth using depth gauge at multiple locations verifying specified depth achieved throughout field. Apply additional infill to low areas identified during depth checking. After sand layer is complete and verified, apply rubber granule layer using similar spreading and brushing technique. Rubber granules should fill pile approximately to two-thirds height leaving visible pile above infill. Power brush entire surface working in multiple directions achieving uniform infill distribution and standing pile fibres upright. Remove excess infill from perimeter areas, markings, or non-playing zones using vacuum or manual collection. For new installations, anticipate some infill settling over first weeks of use requiring topping-up after initial play period.

Safety considerations

Wear P2 or P3 respirators during all infill spreading operations protecting against rubber and sand dust. Position spreader equipment to work with prevailing wind placing operators upwind of dust generation. Use water spray on infill materials before spreading reducing dust generation at source. Take regular breaks from dusty operations every 60 minutes moving to clean air areas for respiratory rest. Maintain hydration during physical spreading work particularly in hot conditions. Watch footing when walking on loose infill as material reduces traction increasing slip risk. Use mechanised equipment for large areas rather than sustained manual spreading preventing cumulative physical strain.

Final Grooming and Quality Verification

Conduct comprehensive final grooming and quality verification before client handover. Use power brush working entire surface in multiple directions ensuring pile fibres stand upright, infill is evenly distributed, and surface has consistent appearance throughout. Remove any visible seam marks or irregularities through brushing. Vacuum or sweep perimeter areas removing loose infill or debris. Inspect all seams carefully checking for complete bonding, no visible gaps, and seam alignment. Test seam strength by attempting to separate edges manually - properly bonded seams should not separate under manual pulling force. Check perimeter fixing is secure throughout by walking perimeter and testing edge security. Measure infill depth at minimum 10 locations across sports fields documenting measurements for client records. Conduct water drainage test by hosing surface and observing drainage pattern - water should drain freely without ponding. Verify surface appearance meets specifications including pile direction consistency, colour uniformity, and overall installation quality. Photograph completed installation from multiple angles for documentation and warranty records. Clean all equipment removing adhesive residues and infill materials before adhesive fully cures. Collect and properly dispose of packaging materials, off-cuts, and waste materials. Remove all tools and equipment from site. Conduct final site cleanup ensuring area is ready for use. Prepare handover documentation including installation date, materials used with batch numbers, infill depth measurements, maintenance recommendations, and warranty information. Meet with client conducting site walk-through demonstrating installation quality, explaining maintenance requirements, and addressing any questions. Provide written maintenance guidelines specific to synthetic grass product installed.

Safety considerations

Wear appropriate PPE during final grooming including hearing protection for power brush operation and dust respirator if dry brushing generates dust. Ensure power brush guard is present and functional preventing contact with rotating brush. Verify electrical safety on powered equipment including RCD protection and undamaged leads. Watch footing on synthetic surfaces which can be slippery particularly when new or if residual adhesive is present on surface. Clean up adhesive spills immediately using appropriate solvents and absorbents preventing slip hazards and environmental contamination. Dispose of adhesive waste and contaminated materials appropriately following manufacturer and regulatory requirements - do not place in general waste. Conduct final safety inspection of completed installation identifying any sharp edges, protruding fixings, or other hazards requiring attention before handover.

Frequently asked questions

What base preparation is required for successful synthetic grass installation?

Base preparation is the most critical factor determining long-term synthetic grass performance and longevity. For residential landscape installations, typical base consists of 75-100mm compacted crushed rock or decomposed granite achieving firm, stable surface with 1:100 minimum gradient for drainage. Base material should be clean angular aggregate (typically 5-10mm size) compacting well without excessive fine content that impedes drainage. Compact base using plate compactor in 50mm layers achieving minimum 95% maximum dry density ratio. Check compaction using drop test (no visible surface movement under hammer blows) or density testing for critical applications. Level base surface using screed boards and laser level achieving ±5mm tolerance for residential installations. For sports fields, base requirements are more stringent including 150-300mm compacted aggregate base in lifts not exceeding 75mm thickness, laser levelling achieving ±3mm tolerance across playing surface, 1:100 minimum gradient for drainage with crossfall and longitudinal fall coordinated to drain to perimeter collection systems, and possible installation of subsurface drainage systems for sites with poor natural drainage. Base must achieve minimum 98% compaction for sports surfaces preventing settlement under intensive use. Install shock pad systems for sports fields after base completion, adhesive-bonding shock pad to base achieving complete contact without voids or bubbles. Poor base preparation causes multiple problems including surface undulations from differential settlement appearing within months of installation, ponding and drainage problems from inadequate gradients or compaction, joint separation from differential movement between turf sections, and premature surface failure requiring complete reinstallation. Cost of base reconstruction far exceeds savings from inadequate initial preparation. Do not proceed with synthetic grass installation over questionable bases - require base rectification before commencing ensuring successful long-term outcomes.

What adhesive safety precautions are essential during seam joining work?

Adhesive safety during synthetic grass installation requires multiple controls addressing respiratory exposure, skin contact, and fire hazards. Two-component polyurethane adhesives used for seam joining contain isocyanate components that release vapours during mixing and application causing respiratory irritation, sensitisation, and potential long-term health effects. Respiratory protection using half-face or full-face respirators with organic vapour cartridges rated for isocyanate service is mandatory for all workers involved in adhesive work. Standard dust masks or P2 respirators without vapour filtration provide no protection. Fit test respirators annually to each worker verifying adequate seal. Replace organic vapour cartridges after 8 hours use or if chemical odours become noticeable indicating cartridge saturation. For enclosed installation spaces including undercover areas or indoor sports facilities, higher-level protection including supplied air respirators or powered air purifying respirators (PAPR) may be necessary. Ventilation is critical - work outdoors in well-ventilated areas where possible. Use portable fans creating airflow across work area directing vapours away from worker breathing zones. Open all doors and windows in enclosed spaces before commencing adhesive work. Schedule adhesive work during cooler morning periods when vapour generation is reduced and worker tolerance for respirator wear is higher. Skin protection requires chemical-resistant nitrile gloves throughout all adhesive handling from mixing through application and cleanup. Remove gloves carefully preventing contact with contaminated outer surfaces. Wash hands thoroughly after completing adhesive work before eating, drinking, or smoking. Avoid skin contact with mixed adhesive - if contact occurs, clean immediately with appropriate solvent then wash with soap and water. Do not use solvents to clean adhesive from skin as solvents can drive chemicals into skin. Fire hazards exist during adhesive handling as some components have low flash points. Prohibit smoking, open flames, and hot work including grinding or welding near adhesive work areas. Store adhesive components in cool, well-ventilated areas away from ignition sources. Dispose of adhesive waste appropriately - do not place in general waste. Follow manufacturer Safety Data Sheets (SDS) for specific product requirements.

How should installation crews manage heat stress during summer synthetic grass installation?

Heat stress management is critical during summer synthetic grass installation as multiple factors combine creating dangerous conditions. Synthetic grass surfaces absorb solar radiation reaching temperatures 30-50°C above ambient temperature, with surface temperatures commonly exceeding 60°C during summer installation work. Installers work directly on these hot surfaces during roll placement, seam joining, and infill spreading experiencing radiant heat in addition to direct solar exposure and metabolic heat from sustained physical work. Implement comprehensive heat stress controls starting with work scheduling modifications. During summer months (November-March), commence work at 6am completing physically demanding tasks including roll handling, base verification, and initial layout before 11am when temperatures rise. Schedule seam joining work (most critical timing-dependent task) for morning periods when temperatures are lower and adhesive working time is longer. Consider evening work periods (after 5pm) during extreme heat events if adequate lighting can be provided. Hydration management is essential - provide iced water and electrolyte drinks in coolers maintaining continuous availability throughout workday. Mandate 10-minute hydration breaks every 30 minutes when temperatures exceed 30°C. Brief workers that plain water alone is insufficient for replacing salts lost through heavy sweating - provide commercial electrolyte drinks or make electrolyte solution using water, salt, and cordial. Establish shaded rest area using marquee, vehicle canopy, or existing structures providing escape from direct sun during breaks. Cooling measures include providing cooling vests or neck cooling towels for workers conducting sustained physical work, allowing workers to wet shirts and hats with water for evaporative cooling, and providing ice for placing in hats or bandanas. Monitor worker behaviour for heat stress symptoms including reduced work rate, irritability, unsteady movement, confusion, or cessation of sweating. Any worker displaying heat stress symptoms must cease work immediately, move to shade, commence active cooling using wet towels and fans, and consume fluids if conscious. Severe heat stress requires emergency medical response - call 000 if worker becomes confused, loses consciousness, or shows signs of heat stroke. Weather monitoring is essential - check Bureau of Meteorology forecasts each morning adjusting schedules based on predicted conditions. Cease outdoor work entirely if forecast temperatures exceed 38°C or if heat stress symptoms develop in any worker. Document heat stress management procedures in toolbox meetings and ensure all crew members understand symptoms and response protocols.

What quality control measures ensure successful synthetic grass seam joining?

Seam quality directly affects installation appearance and longevity making quality control during seam joining essential. Pre-work controls include verifying correct adhesive product for installation conditions - outdoor installations require exterior-grade polyurethane adhesives whilst indoor installations may use alternative adhesive systems. Check adhesive batch numbers and expiration dates - expired adhesive may not cure properly. Verify weather conditions are suitable for adhesive application - most products require temperatures between 10-30°C and no rain forecast during application and cure period. Prepare seam edges carefully cutting clean, straight edges through backing without ragged edges or incomplete cuts that prevent intimate contact between backing and adhesive. Clean cut edges removing loose fibres, backing fragments, or debris that could interfere with bonding. Position seam tape accurately centered beneath seam gap ensuring tape lies flat without wrinkles or air pockets that create weak bonds. Mix adhesive accurately following manufacturer instructions - incorrect mixing ratios prevent proper cure. Use mixing equipment (paddle mixer) rather than hand stirring achieving complete component integration visible through uniform colour. Adhesive should show no colour streaking or separation after mixing. Apply adhesive at specified coverage rate using calibrated application equipment - excessive adhesive causes seep-through to surface whilst insufficient adhesive creates weak bonds. Typical coverage is 400-600 grams per linear metre but verify manufacturer specifications. Work within adhesive pot life (typically 15-30 minutes depending on temperature) completing seam before adhesive becomes tacky or starts gelling. Bring cut edges together accurately with minimal gap (less than 2mm) achieving near-invisible join line. Use roller or hand pressure ensuring complete backing contact with adhesive throughout seam length. Check for adhesive seep-through to surface - excessive seep-through indicates over-application requiring immediate cleanup using appropriate solvent. Weight seams during cure preventing edge lift or separation particularly important on sports fields where seam quality is critical. Do not walk on seams for minimum 4 hours allowing initial cure. Test seam strength after 24-hour cure by attempting to manually separate edges - properly bonded seams should not separate under firm manual pulling force. Document seam work including adhesive batch numbers, weather conditions, and cure times for warranty records. Failed seams require remedial work including seam separation, surface cleaning, and re-joining using fresh adhesive - prevention through quality control is far preferable to remediation.

What maintenance requirements should installers communicate to clients at handover?

Comprehensive maintenance guidance at handover ensures clients understand care requirements maintaining synthetic grass appearance and performance throughout expected lifespan. Regular maintenance includes removal of debris and organic matter using leaf blowers, vacuums, or stiff brooms weekly or more frequently in areas with heavy leaf fall. Organic material left on surface decomposes creating staining and potentially supporting weed growth at surface. For pet areas, remove solid waste immediately and rinse urine areas with water to prevent odours and bacterial growth. Power brush sports fields monthly or more frequently with intensive use to maintain pile fibre orientation, redistribute infill maintaining consistent depth and coverage, prevent compaction particularly in high-traffic areas including goals and centres, and maintain consistent surface performance characteristics. Annual power brushing is minimum for residential landscape applications. Deep cleaning every 12-24 months using rotary brush equipment and/or high-pressure washing removes ingrained dirt, biological growth, and pollution residues maintaining appearance and surface properties. Use only approved cleaning products following manufacturer recommendations - inappropriate chemicals can damage synthetic fibres or backing. Infill management for sports surfaces includes periodic depth checks at multiple locations verifying specified depth is maintained, topping-up infill in high-wear areas particularly goals, centre circles, and sideline areas where intensive use depletes infill, and potentially replacing infill after 5-8 years as infill materials degrade from UV exposure and mechanical action. Monitor seams regularly checking for separation or edge lift requiring prompt repair preventing progressive damage. Check perimeter fixing remains secure particularly after extreme weather events. Address damage promptly - small issues repaired immediately prevent progressive damage requiring extensive remediation. Common damage includes burns from cigarettes or fireworks requiring patch repairs, tears or punctures requiring seaming or patch repairs, and seam separation requiring re-joining. Avoid placing extremely hot objects on synthetic grass including barbecues, fire pits, or metal furniture in direct sunlight as heat damage is permanent. Prohibit vehicle traffic on residential installations as vehicle weight and tyre loads damage synthetic grass and backing. For sports fields, vehicle access should be limited to dedicated access routes or use ground protection mats preventing damage. Provide written maintenance guidelines specific to product installed including recommended maintenance frequency, approved cleaning products, and contact information for maintenance service providers or product technical support. Schedule 12-month post-installation inspection with client reviewing surface condition, addressing any maintenance questions, and identifying any warranty issues requiring attention.
