Our team specifies PP+Net and PU backings for our line because the hidden layer decides how long the surface lasts.<\/p>\n<p>A PP+Net backing typically lasts six to eight years while a PU backing runs twelve to fifteen years. That six to nine year gap is the cost of one wrong choice, so how to choose proper artificial grass backing starts with engineering metrics, not colour.<\/p>\n<h2 id=\"h2_intro\">Why Backing Is the Hidden Half of Artificial Turf<\/h2>\n<p>The pile is what buyers touch, but backing is what the system rests on. We see backing as the keel of a boat: hidden, yet it sets how the whole surface behaves under load and weather.<\/p>\n<p>Our opinion is plain. Backing is the most under-rated line item in a turf contract because the error shows up years later. How to choose proper artificial grass backing therefore begins with the base, then climate, roll width, install method and price.<\/p>\n<p>Most top pages still list materials and stop there. We instead give a decision order: match backing drainage to the base, then fit the climate, then set the roll width, then pick the seam, then read the price band. Each step is a measurable field, not a colour swatch.<\/p>\n<h2 id=\"h2_drainage\">Matching Backing Drainage to Your Base Drainage<\/h2>\n<p>Top turf moves about thirty plus inches of rain per hour per square yard when the backing is open. The base beneath must drain at least as fast, or water ponds on the surface after <a href=\"https:\/\/en.wikipedia.org\/wiki\/Infiltration_(hydrology)\" target=\"_blank\" rel=\"noopener\">infiltration<\/a> stalls.<\/p>\n<p>We treat backing and base as one hydraulic system. A backing that out-drains a weak base still floods, and a strong base behind a clogged backing still ponds. The two rates must meet before the roll is laid.<\/p>\n<figure>\n<img src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-featured.webp\" alt=\"Artificial turf surface detail: Golf practice setup with a green hitting mat, yellow practice balls, a\" width=\"1200\" height=\"675\" class=\"wp-image-1277\" loading=\"lazy\" decoding=\"async\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-featured.webp 1200w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-featured-300x169.webp 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-featured-1024x576.webp 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-featured-768x432.webp 768w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-featured-18x10.webp 18w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption>Three perforation patterns \u2014 hole-punch, flow-through and non-perforated \u2014 move water through the backing at different rates.<\/figcaption><\/figure>\n<p>Three perforation styles set the rate. Hole-punch suits homes and parks. Flow-through suits pets and wet sites. Non-perforated suits putting greens that rely on heavy infill to stay flat.<\/p>\n<p>Hole spacing runs about fifty to two hundred millimetres with five to ten millimetre holes in common spec.

Our line uses it as the standard drainage backing for landscape and light traffic where the climate stays mild and the load stays low.<\/p>\n<p>A PP+Net backing typically serves six to eight years in normal use. Under desert UV that window can shrink to four to six years, which is why we track each site&#8217;s sun load before we recommend it.<\/p>\n<figure>\n<img src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-slot2.webp\" alt=\"Artificial turf surface detail: Person's legs standing on a putting mat beside a hitting mat and balls\" width=\"1200\" height=\"900\" class=\"wp-image-1279\" loading=\"lazy\" decoding=\"async\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-slot2.webp 1200w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-slot2-300x225.webp 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-slot2-1024x768.webp 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-slot2-768x576.webp 768w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-slot2-16x12.webp 16w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption>A wide roll unrolled on a compacted base shows how roll width couples to backing weight during handling.<\/figcaption><\/figure>\n<p>We once revisited a desert demo laid with PP+Net after the first hot summer. The edge had stiffened and a seam had lifted; the backing had lost flexibility faster than the buyer expected from a mild-climate spec.<\/p>\n<p>PP+Net is not latex. The net is a structure, latex is a glue type some coats use. We keep that distinction clear because buyers often mix the two when they ask for a &#8220;standard&#8221; backing on a quote.<\/p>\n<table>\n<thead>\n<tr>\n<th>Scenario<\/th>\n<th>PP+Net fit<\/th>\n<th>Note<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Residential landscape<\/td>\n<td>Yes<\/td>\n<td>Mild climate only<\/td>\n<\/tr>\n<tr>\n<td>Temporary exhibit<\/td>\n<td>Yes<\/td>\n<td>Short term use<\/td>\n<\/tr>\n<tr>\n<td>Mid-low traffic<\/td>\n<td>Yes<\/td>\n<td>Light load<\/td>\n<\/tr>\n<tr>\n<td>Standard climate<\/td>\n<td>Yes<\/td>\n<td>No extremes<\/td>\n<\/tr>\n<tr>\n<td>Desert UV<\/td>\n<td>Limited<\/td>\n<td>Life drops to 4\u20136 yr<\/td>\n<\/tr>\n<tr>\n<td>Coastal salt<\/td>\n<td>No<\/td>\n<td>Coating degrades<\/td>\n<\/tr>\n<tr>\n<td>Heavy wet<\/td>\n<td>No<\/td>\n<td>Holes clog<\/td>\n<\/tr>\n<tr>\n<td>Freeze-thaw<\/td>\n<td>No<\/td>\n<td>Net can tear<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>For coastal salt, heavy wet and freeze-thaw we steer buyers away from PP+Net.

Our line specifies it for commercial, sports and pet sites where the surface works hard every day.<\/p>\n<p>A PU backing typically serves twelve to fifteen years. Its dimensional stability holds from about minus forty to plus eighty degrees Celsius, so desert and freeze zones stay safe through the year.<\/p>\n<figure>\n<img src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-slot3.webp\" alt=\"Artificial turf surface detail: Yellow-green golf ball beside the cup on a putting green; ball and hol\" width=\"1200\" height=\"900\" class=\"wp-image-1280\" loading=\"lazy\" decoding=\"async\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-slot3.webp 1200w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-slot3-300x225.webp 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-slot3-1024x768.webp 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-slot3-768x576.webp 768w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/hitting-off-mats-grass-turf-practice-ruin-swing-slot3-16x12.webp 16w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption>PU heat-welded seam on the left against PP+Net seam tape with adhesive on the right.<\/figcaption><\/figure>\n<p>In our coating hall we join PU with a heat-welded seam. The iron fuses the two edges with no glue, which removes chemical residue and gives a cleaner seam than tape can reach on a long run.<\/p>\n<p>PU resists liquid, so pet urine and coastal salt will not soak in or smell. SBR and latex coats can crack or grow mould in heat and moisture, which is why we rarely suggest them for wet sites.<\/p>\n<table>\n<thead>\n<tr>\n<th>Scenario<\/th>\n<th>PU fit<\/th>\n<th>Note<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>High-end home<\/td>\n<td>Yes<\/td>\n<td>Long life<\/td>\n<\/tr>\n<tr>\n<td>Commercial landscape<\/td>\n<td>Yes<\/td>\n<td>Heavy use<\/td>\n<\/tr>\n<tr>\n<td>Play area<\/td>\n<td>Yes<\/td>\n<td>Impact safe<\/td>\n<\/tr>\n<tr>\n<td>Pet turf<\/td>\n<td>Yes<\/td>\n<td>No odour<\/td>\n<\/tr>\n<tr>\n<td>Hot desert<\/td>\n<td>Yes<\/td>\n<td>Holds to 80\u00b0C<\/td>\n<\/tr>\n<tr>\n<td>Humid coastal<\/td>\n<td>Yes<\/td>\n<td>No mould<\/td>\n<\/tr>\n<tr>\n<td>Freeze-thaw<\/td>\n<td>Yes<\/td>\n<td>No tear<\/td>\n<\/tr>\n<tr>\n<td>Low-budget temp<\/td>\n<td>Limited<\/td>\n<td>Cost is high<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>PU weighs about thirty to fifty percent more than PP+Net per roll. That extra mass couples to roll width and crew size, which we cover in the next section on climate and install.<\/p>\n<h2 id=\"h2_climate_install\">Climate, Roll Width, and Installation Method<\/h2>\n<p>Climate sets the backing first. Hot desert above forty-five Celsius calls for PU. Humid coast calls for PU to block odour. Freeze-thaw below minus twenty calls for PU to stop tears. Temperate sites can use PP+Net.<\/p>\n<p>Roll width then meets backing weight. A two metre by twenty-five metre roll covers fifty square metres and stays light. A five metre by twenty-five metre roll covers one hundred twenty-five square metres but needs a bigger crew.<\/p>\n<p>Seam count follows width. A thousand square metres in two metre rolls needs four to five seams; in five metre rolls it needs only one to two. Fewer seams mean fewer leak paths and a longer life for the field.<\/p>\n<table>\n<thead>\n<tr>\n<th>Climate<\/th>\n<th>Backing<\/th>\n<th>Roll width<\/th>\n<th>Install<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Hot desert<\/td>\n<td>PU<\/td>\n<td>4\u20135 m<\/td>\n<td>Heat weld<\/td>\n<\/tr>\n<tr>\n<td>Humid coast<\/td>\n<td>PU<\/td>\n<td>4 m<\/td>\n<td>Heat weld<\/td>\n<\/tr>\n<tr>\n<td>Freeze-thaw<\/td>\n<td>PU<\/td>\n<td>2\u20135 m<\/td>\n<td>Heat weld<\/td>\n<\/tr>\n<tr>\n<td>Temperate<\/td>\n<td>PP+Net<\/td>\n<td>2\u20134 m<\/td>\n<td>Seam tape<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Install method locks to backing.

PU is a polyurethane coat that resists heat, moisture and tears. We choose PU when the site sees heavy use or extreme weather.<\/p>\n<\/div>\n<div class=\"faq-card\">\n<h3>Which backing is best for hot climates?<\/h3>\n<p>PU backing is the safe pick for hot climates above 45\u00b0C. Its dimensional stability holds from about -40\u00b0C to +80\u00b0C while PP+Net can stiffen and crack under desert UV. We specify PU for any desert or rooftop site.<\/p>\n<\/div>\n<div class=\"faq-card\">\n<h3>Which backing is best for heavy rain or coastal humidity?<\/h3>\n<p>For heavy rain or coastal humidity we recommend PU. It does not absorb liquid, so pet urine and salt air will not breed odour or mould. Flow-through perforation on the backing also keeps the base from ponding.<\/p>\n<\/div>\n<div class=\"faq-card\">\n<h3>Does PU backing last longer than PP backing?<\/h3>\n<p>Yes. A PP+Net backing typically serves six to eight years, while PU runs twelve to fifteen years. That gap is the reason we push PU for long-life commercial and sports contracts where downtime costs more.<\/p>\n<\/div>\n<div class=\"faq-card\">\n<h3>How do I check the drainage rate of artificial turf backing?<\/h3>\n<p>Ask the supplier for the drainage rate in inches per hour per square yard and the perforation pattern. We test one roll on intake with a simple field kit; if the rate falls short of the base capacity, we reject the shipment.<\/p>\n<\/div>\n<div class=\"faq-card\">\n<h3>Can PP and PU backing be used with seaming tape and adhesive?<\/h3>\n<p>PU is usually joined with a heat-welded seam for zero glue residue, though seaming tape works. PP+Net is commonly joined with seam tape and two-part adhesive. Both methods are valid; the choice follows the site and crew.<\/p>\n<\/div>\n<p><script type=\"application\/ld+json\" id=\"evo301-geo-ai-block\">\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"Organization\",\n  \"name\": \"Relyir Artificial Grass\",\n  \"url\": \"https:\/\/www.relyirgrass.com\/\",\n  \"areaServed\": [\"North America\",\"Europe\",\"Middle East\",\"Oceania\",\"Africa\"],\n  \"address\": {\n    \"@type\": \"PostalAddress\",\n    \"addressRegion\": \"Jiangsu\",\n    \"addressCountry\": \"CN\"\n  }\n}\n<\/script><\/p>\n<p><script type=\"application\/ld+json\">\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"Article\",\n  \"headline\": \"How to Choose the Proper Artificial Grass Backing\",\n  \"description\": \"PP+Net or PU backing: how to choose by climate, base drainage, roll width and install method.
