A grounds team notices that one goalmouth stays slick after rain. Brushing no longer lifts the pile, and the infill order keeps growing.<\/p>\n<p>Deciding when to replace your artificial turf field should not depend on who argues hardest in a budget meeting. Our team builds rolls to spec for school, club and municipal projects. The replacement calls that survive scrutiny are written down. They record measured pile height, logged infill depth, impact readings and drainage times, all set against the original specification.<\/p>\n<h2 id=\"why-replacement-calls-need-measurements\">Why Replacement Calls Need Measurements, Not Instinct<\/h2>\n<p>Age is the least useful number in a field file. Published service lives for sports turf run from eight to fifteen years. Most manufacturer warranties sit near the eight-year mark. Two fields opened in the same summer can sit a decade apart in condition.<\/p>\n<p>Three measurements answer when to replace your field: how much pile is left, how hard the surface reads, and how fast water leaves it. Colour, seam cosmetics and player opinion are context, not evidence.<\/p>\n<p>Across the artificial turf installations we build rolls for, the pattern repeats. The reading that eventually closes a pitch is hardness, not appearance. Operators who log numbers every season never have to argue about timing.<\/p>\n<table>\n<thead>\n<tr>\n<th>Signal<\/th>\n<th>Threshold to watch<\/th>\n<th>What it tells you<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Residual pile height<\/td>\n<td>Installed 50 to 55 mm for campus, 55 to 60 mm for training and 60 to 65 mm for competition; alarm below 1 inch<\/td>\n<td>Fibre structure is gone, not merely flattened<\/td>\n<\/tr>\n<tr>\n<td>Impact reading<\/td>\n<td>Target 100 to 165; ceiling at 200<\/td>\n<td>Surface no longer absorbs enough energy<\/td>\n<\/tr>\n<tr>\n<td>Shock absorption<\/td>\n<td>55 to 70 percent<\/td>\n<td>Cushioning has drifted outside the playable band<\/td>\n<\/tr>\n<tr>\n<td>Infill depth<\/td>\n<td>1.0 to 1.875 inches; top up past 20 percent loss<\/td>\n<td>Fill has migrated or compacted<\/td>\n<\/tr>\n<tr>\n<td>Permeability<\/td>\n<td>Turf layer 10 in.\/hr, base 14 in.\/hr<\/td>\n<td>Backing or base is blocking water<\/td>\n<\/tr>\n<tr>\n<td>Seam and tuft bind<\/td>\n<td>Gaps beyond a few mm; 6 to 8 lbf<\/td>\n<td>Carpet structure itself is failing<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Read the middle column as pass-fail bands rather than averages. A single test point outside the band in a high-use zone is enough to open the file.<\/p>\n<h2 id=\"fibre-wear-residual-pile-height\">Fibre Wear: Residual Pile Height and Breakage<\/h2>\n<p>Pile height is the easiest signal to be optimistic about. Campus fields are commonly specified at 50 to 55 mm. Competition surfaces start at 60 to 65 mm. A field at the top of that band has a long way to fall before it looks wrong.<\/p>\n<p>The working threshold is plainer than it sounds. Fibre shorter than 1 inch in a wear lane is past grooming. Split tips, brittle ends and matting that brushing will not lift all point the same way.<\/p>\n<div class=\"wp-block-image\">\n<figure><img decoding=\"async\" src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/high-artificial-turf-be-featured.webp\" alt=\"Bright green turf with fine, full fibres\" class=\"wp-image-1336\" width=\"1200\" height=\"675\" loading=\"lazy\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/high-artificial-turf-be-featured.webp 1200w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/high-artificial-turf-be-featured-300x169.webp 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/high-artificial-turf-be-featured-1024x576.webp 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/high-artificial-turf-be-featured-768x432.webp 768w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/high-artificial-turf-be-featured-18x10.webp 18w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption>Bright green turf with fine, full fibres<\/figcaption><\/figure>\n<\/div>\n<p>Heavy-use artificial turf installations lose fibre fastest where players plant and turn. Watch goalmouths, centre circles, penalty spots and the run-in front of a dugout. Take readings with a probe at mapped points, not by eye.<\/p>\n<p>Yarn shape and polymer matter as much as height. We point buyers at <a href=\"https:\/\/www.relyirgrass.com\/wear-resistance-artificial-lawn\/\">how fibre construction resists abrasion<\/a> before they fix a replacement specification.<\/p>\n<h2 id=\"compaction-and-shock-absorption-drift\">Compaction and the Shock Absorption Drift<\/h2>\n<p>Infill compacts. That is physics rather than a maintenance failure. Well-kept artificial turf installations still harden with age, which is why the impact reading settles when to replace your surface, not the calendar.<\/p>\n<p>The standard drop test reports a single Gmax figure. Healthy fields usually sit between 80 and 120. Remediation is advised above 165. A reading of 200 is the ceiling that takes a field out of use.<\/p>\n<p>Our separate piece on <a href=\"https:\/\/www.relyirgrass.com\/g-max-testing-how-does-it-prevent-turf-injuries\/\">how impact testing is run on a sports surface<\/a> covers the protocol. It is ten points, three drops each, and the average of the second and third.<\/p>\n<div class=\"wp-block-image\">\n<figure><img decoding=\"async\" src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/build-backyard-putting-green-body-4.webp\" alt=\"Artificial turf surface detail: Golf ball beside the cup with a red flagstick on a putting green; ball\" class=\"wp-image-890\" width=\"1100\" height=\"733\" loading=\"lazy\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/build-backyard-putting-green-body-4.webp 1100w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/build-backyard-putting-green-body-4-300x200.webp 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/build-backyard-putting-green-body-4-1024x682.webp 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/build-backyard-putting-green-body-4-768x512.webp 768w\" sizes=\"auto, (max-width: 1100px) 100vw, 1100px\" \/><figcaption>Sunlit green grass blades close up<\/figcaption><\/figure>\n<\/div>\n<p>Force reduction is the share of impact energy the surface absorbs. International programmes that test football turf grade it in a band of 55 to 70 percent. As infill compacts and any shock layer degrades, that figure drifts down while Gmax drifts up.<\/p>\n<p>Treat the two together. A field can pass a spot reading and still absorb far less energy than at handover. That drift reaches players long before it reaches a photograph.<\/p>\n<h2 id=\"infill-loss-topping-up-cannot-fix\">Infill Loss That Topping Up Cannot Fix<\/h2>\n<p>Sand and rubber do different jobs and leave at different rates. Typical specifications put stabilising sand at 20 to 30 kg per square metre. Performance rubber runs at 5 to 8 kg per square metre. A combined system sits at 30 to 40 kg per square metre.<\/p>\n<p>Depth is the number that matters, not tonnage. Hold the specified depth. Top up and regrade once wear lanes sit more than 20 percent under target. Most programmes also budget for replenishing 5 to 10 percent of rubber every one to two years.<\/p>\n<div class=\"wp-block-image\">\n<figure><img decoding=\"async\" src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-turf-making-sure-every-certificate-is-real-and-cu-perspective.webp\" alt=\"Turf samples laid side by side with seams between them\" class=\"wp-image-1065\" width=\"1200\" height=\"803\" loading=\"lazy\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-turf-making-sure-every-certificate-is-real-and-cu-perspective.webp 1200w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-turf-making-sure-every-certificate-is-real-and-cu-perspective-300x201.webp 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-turf-making-sure-every-certificate-is-real-and-cu-perspective-1024x685.webp 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-turf-making-sure-every-certificate-is-real-and-cu-perspective-768x514.webp 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption>Turf samples laid side by side with seams between them<\/figcaption><\/figure>\n<\/div>\n<p>The failure signal is repeat business. Two artificial turf installations laid from identical rolls can age a decade apart on infill management alone. When yet another top-up in the same season changes nothing, the carpet has stopped holding the fill.<\/p>\n<h2 id=\"seams-wrinkles-and-backing-failure\">Seams, Wrinkles and Backing Failure<\/h2>\n<p>Seams fail before carpets do. A gap that reopens after repair means the bond has gone. So does one longer than a few millimetres along a run.<\/p>\n<p>Back that up with two measurable checks. Installation guidance calls for seam strength of at least 30 N per cm. Many systems expect tuft bind above 6 to 8 lbf. Below either figure, fibre pulls free and wrinkles start to travel.<\/p>\n<div class=\"wp-block-image\">\n<figure><img decoding=\"async\" src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/playground-artificial-grass-safety-body-2.webp\" alt=\"Artificial turf surface detail: Girl climbing on blue and green play equipment; person and colored sur\" class=\"wp-image-891\" width=\"1200\" height=\"801\" loading=\"lazy\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/playground-artificial-grass-safety-body-2.webp 1200w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/playground-artificial-grass-safety-body-2-300x200.webp 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/playground-artificial-grass-safety-body-2-1024x684.webp 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/playground-artificial-grass-safety-body-2-768x513.webp 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption>Dense green grass with a blurred background<\/figcaption><\/figure>\n<\/div>\n<p>On older artificial turf installations, look underneath as well. Backing that has gone brittle, cracked or delaminated cannot be re-bonded. No infill work will hold a carpet that has lost its own substrate.<\/p>\n<h2 id=\"drainage-rate-markings-layout-drift\">Drainage Rate, Markings and Layout Drift<\/h2>\n<p>Water is the honest test, because it cannot be argued with. Minimum permeability guidance puts the turf and infill layer at 10 in.\/hr. The base and finish stone sit at 14 in.\/hr. The field test is blunt: after rainfall, note any standing water after 30 minutes.<\/p>\n<p>Slow drainage is usually a base problem wearing a carpet disguise. It is worth reading <a href=\"https:\/\/www.relyirgrass.com\/put-under-artificial-grass-for-drainage-complete-guide\/\">what sits under the carpet and how the base is graded<\/a>. The layers below decide whether the system works at all.<\/p>\n<p>Markings fail on the same clock. Line and inlay work is set out to a tolerance below 3 mm. Once lines are repainted twice a season and the geometry still drifts, the surface underneath has moved. Faded lines alone are cosmetic. Lines that will not stay put are a structural note.<\/p>\n<h2 id=\"repair-versus-replace-economic-crossover\">Repair Versus Replace: The Economic Crossover<\/h2>\n<p>Repair is cheap and short. An infill refresh costs a fraction of replacement and closes a field for hours to a day. A minor top-off runs about 2 to 3 days. A sectional replacement takes 2 to 3 weeks.<\/p>\n<p>The crossover shows up in the log rather than the invoice. When the same zones need work twice in a season, you have passed it. So too when readings stay high after decompaction and top-up. The question stops being whether and becomes when to replace your surface.<\/p>\n<table>\n<thead>\n<tr>\n<th>Condition<\/th>\n<th>Repair path<\/th>\n<th>Replace trigger<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Infill low in wear lanes<\/td>\n<td>Top up and regrade<\/td>\n<td>Short again within the same season<\/td>\n<\/tr>\n<tr>\n<td>Hard surface readings<\/td>\n<td>Decompact, brush, retest<\/td>\n<td>Still above 200 after decompaction<\/td>\n<\/tr>\n<tr>\n<td>Single lifted seam<\/td>\n<td>Re-bond the run<\/td>\n<td>Gaps reopen along long runs<\/td>\n<\/tr>\n<tr>\n<td>Localised puddle<\/td>\n<td>Relevel the base spot<\/td>\n<td>Standing water after 30 minutes across zones<\/td>\n<\/tr>\n<tr>\n<td>Marking drift<\/td>\n<td>Repaint to tolerance<\/td>\n<td>3 mm tolerance can no longer be held<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Most artificial turf installations that keep their log current reach replacement talks as planned maintenance, not surprise repair.

They come from how the decision is framed. Four patterns account for most of the late, expensive replacements we see. None of them tell you when to replace your pitch.<\/p>\n<h3>Waiting For a Birthday Instead of a Reading<\/h3>\n<p>Calendars do not wear out fields. A surface at eight years with sound readings may have seasons left. One at six with high impact numbers does not. Test first, then date the replacement.<\/p>\n<h3>Treating Colour Loss as the Trigger<\/h3>\n<p>Fading is cosmetic until it arrives with fibre shearing and brittle tips. Judge the surface on residual pile height and impact readings. Let appearance be the last item on the sheet.<\/p>\n<h3>Buying Infill Instead of Answers<\/h3>\n<p>Topping up is correct when the carpet is sound and wrong when it is not. Repeated top-ups in a season with no movement in the readings is a replacement decision dressed as maintenance.<\/p>\n<h3>Starting the Procurement File in the Off-Season<\/h3>\n<p>The window closes faster than it looks. Base works alone can run 7 to 14 days. A school-sized field takes roughly 20 to 30 days end to end before weather delays. Open the file a year out.<\/p>\n<h2 id=\"replacement-season-checklist-for-operators\">A Replacement Season Checklist For Operators<\/h2>\n<p>What follows is the sequence we recommend to grounds teams. It fits on one page, and it produces the kind of file a board will approve.<\/p>\n<h3>Pull the Original Specification<\/h3>\n<p>Pile height, yarn type, infill type and depth, shock layer detail and roll layout. Without the as-built specification there is no baseline. Every reading taken afterwards is only an opinion.<\/p>\n<h3>Map and Probe Fixed Test Points<\/h3>\n<p>Choose ten points covering wear lanes, centre, corners and known wet spots. Log infill depth and residual pile at each one every season. The trend becomes visible well before the failure does.<\/p>\n<h3>Book Independent Impact Testing<\/h3>\n<p>A full assessment every one to two years is the norm, and yearly once a field passes eight seasons. Use a third-party tester. One municipal operator saw three different verdicts from three rounds on the same 52 fields.<\/p>\n<h3>Back-Plan the Window From the Fixture List<\/h3>\n<p>Work backwards from the first fixture. Allow 1 to 2 days of testing and 2 to 3 of settlement. Then 3 to 5 days of infill, 3 to 5 of carpet and 7 to 14 of base works. Add tender time on top.
