Water slides off the blades and sits under the sheet, and the failure chain begins: pooling, a musty smell, bubbles under the backing, edges peeling at the perimeter. Buyers often arrive with the costliest misunderstanding already installed: that turf can simply be rolled out over concrete and left. The recurring reports say otherwise: trapped water and odor over sealed slabs, hardness complaints at the top of the list, height conflicts at doors, heat worry around dogs and children. Every one of them traces back to water, heat or height &#8211; the three things a slab cannot absorb.<\/p>\n<p>This guide explains how to install artificial turf on concrete the way we brief dealers. The slab is surveyed before anything is ordered, every fixing choice is a drainage decision, and the walk-away verdict stays on the table. Concrete is not an easier turf site. The engineered base already exists, so the effort moves above it: a water exit path, a comfort layer, a heat strategy.<\/p>\n<h2 id=\"what-a-slab-changes-in-the-installation-math\">What a Slab Changes in the Installation Math<\/h2>\n<p>The case for concrete is structural, not cosmetic. A slab is firm, stable and level, and it will not shift or settle the way soil does. There is no excavation, no compacting and no layers of crushed rock to build. That is why the ability to install artificial turf on concrete pays off fastest on balconies, courtyards, pool surrounds and small patios.<\/p>\n<p>What the slab gives in groundwork, it takes back in consequences. Turf cannot simply be rolled out and left. After the first rain, water pools underneath the sheet, and trapped moisture breeds mold, mildew and a musty smell. Sections bubble underfoot, and un-prepped glue bonds fail so the edges peel. Concrete is non-porous, so water landing on the grass must be given an escape, and a puddle sitting mid-slab turns into smell and algae.<\/p>\n<p>Can you lay artificial turf on concrete? Yes &#8211; once the slab is treated as a base that has already been built, and the work moves above it. The ground-install sequence collapses to four moves: inspect, drain, cushion and fix. What is gained below the slab is owed back above it, because the slab neither absorbs water nor buffers temperature. You can see what a full ground-built base contains in our breakdown of <a href=\"https:\/\/www.relyirgrass.com\/what-goes-under-artificial-grass\/\">what goes under artificial grass: layers and drainage<\/a> &#8211; the slab already is one, minus the drainage.<\/p>\n<h2 id=\"start-with-a-slab-audit-cracks-dips-and-hollow-spots\">Start With a Slab Audit: Cracks, Dips and Hollow Spots<\/h2>\n<p>Every slab conversion starts with a survey, not a roll of turf. Walk the whole area looking for the four findings that decide the job: hollow spots, cracks, low points and contamination. A hollow-sounding garage slab is the classic find, and tapping is how you confirm it.<\/p>\n<figure>\n<img decoding=\"async\" src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-landscaping-flagstone-pavers-green-turf-joints.jpg\" alt=\"rustic outdoor terrace design combining irregular natural flagstones with living-look artificial grass ribbon joints under patio furniture\" width=\"1120\" height=\"680\" class=\"wp-image-2143\" loading=\"lazy\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-landscaping-flagstone-pavers-green-turf-joints.jpg 1120w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-landscaping-flagstone-pavers-green-turf-joints-300x182.jpg 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-landscaping-flagstone-pavers-green-turf-joints-1024x622.jpg 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-landscaping-flagstone-pavers-green-turf-joints-768x466.jpg 768w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-landscaping-flagstone-pavers-green-turf-joints-18x12.jpg 18w\" sizes=\"auto, (max-width: 1120px) 100vw, 1120px\" \/><figcaption>Rustic outdoor terrace design combining irregular natural flagstones with living-look artificial grass ribbon joints.<\/figcaption><\/figure>\n<p>Tap raised or doubtful sections with a rubber mallet and listen. A hollow thud means the concrete has delaminated underneath, and if more than a small section sounds hollow, a concrete contractor is called before anything else is ordered. The audit ends there for that slab; turf is not the repair.<\/p>\n<ul>\n<li>Cracks: hairline ones stay hideable, cracks wider than a quarter inch are flagged at inspection, and cracks or gaps over half an inch are repaired before turf goes down.<\/li>\n<li>Low spots and oil: degrease oil stains because adhesive will not bond to them. Then fill dips with patching or self-levelling compound cured 4 to 8 hours per the manufacturer.<\/li>\n<li>High spots: grind them down, because every imperfection telegraphs through the grass and shows in low sunlight.<\/li>\n<li>Surface character: lightly sand over-polished slabs for adhesive grip and pre-spray shaded, damp areas with an anti-mold treatment. Kill off moss and algae, and let the surface dry thoroughly before anything bonds.<\/li>\n<\/ul>\n<div class=\"callout callout-warning\"><strong>Turf only hides the fault.<\/strong> Over a delaminating slab, the adhesive tears away with the delamination and takes the lawn with it.<\/div>\n<p>None of this is optional polish. The slab will broadcast every flaw straight through the grass, and repairing it now costs less than lifting a lawn later. This audit is the first hour of any honest plan to install artificial turf on concrete.<\/p>\n<h2 id=\"the-water-test-and-the-drainage-fix\">The Water Test and the Drainage Fix<\/h2>\n<h3>Run the Pour Test First<\/h3>\n<p>Drainage is decided before the first roll leaves its wrapper, and the test costs nothing. Wet the entire slab with a hose and watch the water move for five minutes, marking every low spot where it gathers. A spirit level or the same pour tells you whether the fall reads near 1-2% or runs flat. If water runs to a gully, a border or off an edge, the slab is workable. If it puddles in the middle, that water will sit under the grass, and the lawn will smell and grow algae.<\/p>\n<h3>One Question Splits the Fixes<\/h3>\n<p>One question splits the fixes for anyone planning to install artificial turf on concrete: can water escape below the slab? Fake grass on concrete drainage is not a product you buy but a route you choose &#8211; drill, cells, screed or channel, or break-out. The table is the adjudication we use on site.<\/p>\n<table>\n<thead>\n<tr>\n<th>Water&#8217;s outcome<\/th>\n<th>Fix<\/th>\n<th>Key spec<\/th>\n<th>Fits<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Escapes below the slab<\/td>\n<td>Drill weep holes<\/td>\n<td>12-16 mm holes at roughly 0.5-1 m spacing, backfilled with pea gravel<\/td>\n<td>Gardens, patios and slab edges with ground beneath<\/td>\n<\/tr>\n<tr>\n<td>Cannot drain downward<\/td>\n<td>Drainage cells<\/td>\n<td>An airflow gap that disperses water and helps manage pet urine<\/td>\n<td>Balconies, rooftops and interiors<\/td>\n<\/tr>\n<tr>\n<td>The fall itself is wrong<\/td>\n<td>Screed or channel<\/td>\n<td>Self-levelling screed builds a shallow fall; a channel cuts to a drain<\/td>\n<td>Slabs with a drain or edge to reach<\/td>\n<\/tr>\n<tr>\n<td>Nowhere to go<\/td>\n<td>Break-out<\/td>\n<td>The slab is removed and re-poured with a fall<\/td>\n<td>Slabs that hold water with no economic fix<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Match the Fix to the Water&#8217;s Outcome<\/h3>\n<p>Drilling is the fix when water can leave downward. We drill 12-16 mm holes at roughly 0.5-1 m spacing at low points and slab edges, backfilling with pea gravel where clogging is possible. Published specs disagree on the details: 8 to 10 mm holes every 50 centimeters, 16 mm holes, or half-inch weep holes. They describe the same practice, so we spec one usable range rather than crown a single vendor number.<\/p>\n<p>Where water cannot drain downward, drainage cells create an airflow gap that disperses water and manages pet urine. That covers the balcony slab with no drain below, a rooftop, or an interior. Where the fall itself is wrong, a self-levelling screed builds a shallow fall or a channel cuts to a drain.<\/p>\n<p>Occasionally the honest answer is to break the slab out. Whatever the route, fixings never block the water paths: a water-permeable adhesive goes at every fixing point. The wider physics behind these choices sits in our guide to <a href=\"https:\/\/www.relyirgrass.com\/artificial-grass-drainage-bases\/\">artificial grass drainage: bases, slope and perforations<\/a>.<\/p>\n<h2 id=\"the-underlay-decision-comfort-is-the-real-product\">The Underlay Decision: Comfort Is the Real Product<\/h2>\n<p>Hardness underfoot is the number-one complaint people have about artificial grass on concrete, and it is why the underlay is not an accessory. Turf laid straight on a slab feels hard and shows every bump. A perforated foam pad transforms the comfort and hides minor defects for a small extra cost, which makes the pad the real product in most domestic jobs.<\/p>\n<figure>\n<img decoding=\"async\" src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-deck-drainage-pad-roll-grooved-timber-subfloor.jpg\" alt=\"close-up installation shot showing a roll of embossed green drainage shock pad underlayment being laid out across grooved timber deck\" width=\"1120\" height=\"680\" class=\"wp-image-2274\" loading=\"lazy\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-deck-drainage-pad-roll-grooved-timber-subfloor.jpg 1120w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-deck-drainage-pad-roll-grooved-timber-subfloor-300x182.jpg 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-deck-drainage-pad-roll-grooved-timber-subfloor-1024x622.jpg 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-deck-drainage-pad-roll-grooved-timber-subfloor-768x466.jpg 768w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-deck-drainage-pad-roll-grooved-timber-subfloor-18x12.jpg 18w\" sizes=\"auto, (max-width: 1120px) 100vw, 1120px\" \/><figcaption>Close-up installation shot showing a roll of embossed green drainage shock pad underlayment being laid out across.<\/figcaption><\/figure>\n<p>Whatever thickness you choose, the foam must be perforated. Closed-cell foam with no drainage holes moulded through it turns the underlay into a sealed tray &#8211; the opposite of what a slab needs. This is also where artificial turf underlay on concrete differs from a ground install: the pad is doing drainage work, not just cushioning.<\/p>\n<ul>\n<li>5 mm for tight door thresholds and indoor concrete &#8211; the least cushioning.<\/li>\n<li>10 mm for most villa patios and courtyards &#8211; the standard domestic balance.<\/li>\n<li>15 mm for barefoot or children&#8217;s use &#8211; note that it adds height at thresholds and edges.<\/li>\n<li>20 mm for play zones and gym areas over a slab &#8211; the softest and dearest, and it needs trimmed edges.<\/li>\n<\/ul>\n<p>Where children fall, a shock pad comes in 10 mm, 18 mm or 25 mm thicknesses and can reach a critical fall height of up to 2.6 m. An airflow underlay also doubles as a thermal break, stopping the slab from radiating its stored heat back through the blades. For dogs, absorbent foam is never the answer: it soaks urine up and holds the smell.<\/p>\n<div class=\"callout callout-note\" style=\"border-left:4px solid #1a5c2e;background:#f0f7f2;padding:18px 22px;margin:28px 0;border-radius:4px;\"><strong>The two positions do not swap.<\/strong> On a slab shared by pets and children, the pad serves the children and the drainage design serves the dog.<\/div>\n<p>Thickness is only half the decision; the workmanship under the pad decides the rest. Our guide on <a href=\"https:\/\/www.relyirgrass.com\/prepare-surface-lay-synthetic-grass-hard-floor\/\">how to prepare a hard floor for synthetic grass<\/a> covers that surface work in detail. Get the survey and the pad right, and the hardness complaint disappears. And when the plan reaches seam glue, the <a href=\"https:\/\/www.relyirgrass.com\/prepare-base-before-gluing-artificial-turf\/\">base preparation before gluing<\/a> checklist is the gate that keeps the bond alive.<\/p>\n<h2 id=\"fixing-without-pins-glue-tape-or-loose-lay\">Fixing Without Pins: Glue, Tape or Loose Lay<\/h2>\n<p>Pins are off the table before planning starts. There is nothing for them to grip, and driving anything into the slab risks the layer below, so bonding or mechanical edge trims replace mechanical pinning. Fixing decides whether you install artificial turf on concrete reversibly or permanently, and with pins gone it is a three-question function: wind exposure, removal intent, pet use.<\/p>\n<ol>\n<li>Perimeter adhesive &#8211; a 6-8 inch band plus adhesive along seam lines outperforms full-slab coverage, holding the movement-prone edges while preserving center drainage and future repairability. Apply with a notched trowel and let the glue tack up for its open time, typically 10 to 20 minutes, before pressing the turf down.<\/li>\n<li>Removable intent &#8211; heavy-duty outdoor double-sided tape suits balconies, and gaps left in the glue at installation make later removal straightforward. Keep adhesive at the perimeter and key anchor points only, leaving airflow paths that let moisture escape.<\/li>\n<li>Sheltered courtyards &#8211; loose lay with furniture as ballast, the reversible option where wind exposure is never in question. Wind exposure is the decider across all three routes.<\/li>\n<\/ol>\n<p>Two disciplines apply to every way of laying artificial grass on a concrete slab. Leave a small expansion allowance at the edges, because synthetic grass moves with temperature and a lawn fitted tight in cold weather can ripple in a heatwave. Sand ballast is the second hand in a pinless world: it weighs the sheet down and keeps the pile upright when nothing else holds it. Our roundup of <a href=\"https:\/\/www.relyirgrass.com\/secure-artificial-grass-7-ways\/\">seven ways to secure artificial grass<\/a> covers the trim frames that pair with these routes.<\/p>\n<p>Working window and clocks come last in the plan. Adhesive work wants dry, mild conditions between 10 and 30 degrees Celsius, with the slab dry for at least 24 hours beforehand. Keep off the finished surface for 24 hours, and expect full structural cure to stretch to 48-72 hours in cold or humid weather. Can you install artificial grass on concrete without glue? Tape and loose lay both qualify, and a taped or loose-laid sheet can be walked on the same day the slab is dry.<\/p>\n<h2 id=\"seams-edges-and-the-height-you-are-about-to-add\">Seams, Edges and the Height You Are About to Add<\/h2>\n<p>Seams and edges are where a slab install looks either factory-made or homemade. Seaming tape goes shiny side down between the folded-back edges, adhesive goes on the tape, both edges are pressed on, and the seam is walked to bond it. Brushing the fibers upward afterwards hides the join completely.<\/p>\n<figure>\n<img decoding=\"async\" src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-worker-measuring-turf-laminate-floor.jpg\" alt=\"indoor installation setup showing tradesman using a tape measure to accurately cut synthetic grass rug over timber flooring\" width=\"1120\" height=\"680\" class=\"wp-image-2772\" loading=\"lazy\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-worker-measuring-turf-laminate-floor.jpg 1120w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-worker-measuring-turf-laminate-floor-300x182.jpg 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-worker-measuring-turf-laminate-floor-1024x622.jpg 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-worker-measuring-turf-laminate-floor-768x466.jpg 768w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-worker-measuring-turf-laminate-floor-18x12.jpg 18w\" sizes=\"auto, (max-width: 1120px) 100vw, 1120px\" \/><figcaption>Indoor installation setup showing tradesman using a tape measure to accurately cut synthetic grass rug over timber.<\/figcaption><\/figure>\n<p>Two habits keep joins invisible for the life of the lawn. Cut joins as S-seams rather than straight lines so they stay hidden, and run the pile direction of every piece the same way, because mismatched direction shows as shading. Let rolled turf relax in the sun for 1-3 hours before cutting. Cut from the backing side for clean edges, and leave a 1-2 cm buffer for the final trim.<\/p>\n<p>Then comes the arithmetic most people skip. How much height does artificial grass add on concrete? The turf itself runs about 25 mm, the pad adds 5-20 mm, and the two stack 30-45 mm or more onto the slab. Door under-clearance, the first step nosing, and threshold strips or termite barriers are the fixed heights to measure before you install artificial turf on concrete at any of them. Where clearance is tight, the pad drops to 5 mm or the build moves off the door line.<\/p>\n<p>Edges take the most abuse, so where the finish must last, aluminium or composite trim frames do the holding. They shrug off foot traffic and mower wheels that would fray a raw cut edge. A courtyard slab with tight door clearance usually pairs a 5 mm pad with a flat trim so nothing proud crosses the threshold.<\/p>\n<h2 id=\"dogs-heat-and-the-slab-microclimate\">Dogs, Heat and the Slab Microclimate<\/h2>\n<p>A dog patio over sealed concrete is the sharpest test of a slab install. How do you stop artificial grass smelling on concrete? The slab is non-porous, so urine traps between the turf and the slab and builds into ammonia &#8211; a design problem, not a grass problem. The fix combines a drainage-cell air gap, regular enzymatic cleaners and an anti-microbial infill. Our <a href=\"https:\/\/www.relyirgrass.com\/artificial-grass-for-dogs-guide\/\">artificial grass for dogs<\/a> guide carries the full cleaning routine, and the underlay section above explains why an absorbent pad serves children, never dogs.<\/p>\n<figure>\n<img decoding=\"async\" src=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-balcony-penthouse-terrace-dog-yacht-marina.jpg\" alt=\"coastal penthouse terrace surfaced with artificial grass overlooking a yacht harbor and marina\" width=\"1120\" height=\"680\" class=\"wp-image-2121\" loading=\"lazy\" srcset=\"https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-balcony-penthouse-terrace-dog-yacht-marina.jpg 1120w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-balcony-penthouse-terrace-dog-yacht-marina-300x182.jpg 300w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-balcony-penthouse-terrace-dog-yacht-marina-1024x622.jpg 1024w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-balcony-penthouse-terrace-dog-yacht-marina-768x466.jpg 768w, https:\/\/www.relyirgrass.com\/wp-content\/uploads\/2026\/09\/artificial-grass-balcony-penthouse-terrace-dog-yacht-marina-18x12.jpg 18w\" sizes=\"auto, (max-width: 1120px) 100vw, 1120px\" \/><figcaption>Coastal penthouse terrace surfaced with artificial grass overlooking a yacht harbor and marina.<\/figcaption><\/figure>\n<p>How hot does artificial grass get on a concrete slab in summer? Per CHOICE, citing Western Sydney University research, the surface of unshaded artificial turf can reach about 100 degrees Celsius on a hot day, hot enough to burn skin within seconds. In 2020, per the same report, three toddlers sustained second-degree burns walking barefoot over artificial turf at a childcare centre. Radiant heat also raises the surrounding air temperature, and the slab makes it worse: its thermal mass means turf on concrete runs hotter than turf on soil. The response set is cooling infills, shade planning and doubled caution over darker slabs.<\/p>\n<p>Small courtyards add a third layer to the problem. In a low-airflow courtyard, surfaces radiate heat back off the slab and off the surrounding walls, and the air between them simply sits. Shade planning has to account for the whole box, not just the turf.<\/p>\n<div class=\"callout callout-warning\"><strong>Mirrored surfaces melt blades.<\/strong> Glass facades and metal reflections can focus sunlight onto the lawn and melt the pile. Keep the lawn away from mirrored surfaces or plan shading before installation.<\/div>\n<p>None of this argues against the conversion; it argues for designing the microclimate before the roll arrives. Dogs, children and dark slabs all push the same direction: more airflow, more shade, more drainage. Design for the worst afternoon of summer and the rest of the year takes care of itself.<\/p>\n<div class=\"cta-box\" style=\"background:#f0f7f2;border:2px solid #1a5c2e;border-radius:8px;padding:28px;margin:0 0 28px;\">\n<h3 style=\"color:#1a5c2e;margin-top:0;\">Slab Cracked Where the Grass Will Lie?<\/h3>\n<p style=\"margin-bottom:18px;\">Send the slab dimensions and intended use.

Silica sand is the ballast that keeps a pinless sheet flat and the pile upright on a slab. Spread it with a drop spreader, brush it in against the pile, and plan a light top-up every 1-2 years. One caution rules the job: never overpack infill near drainage holes, because packed sand seals them shut.<\/p>\n<ol>\n<li>Seams run gap-free under a hand pressed flat against the join.<\/li>\n<li>Edges sit pressed down, with no lift at the perimeter or the trim line.<\/li>\n<li>The hose test is re-run to confirm the water paths survived the build &#8211; the loop closed with the drainage section.<\/li>\n<\/ol>\n<p>The first week is for catching what the checklist missed. Bubbles or wrinkles mean lift, re-stretch and re-weight while the bond is still young. Done in that window the correction is quick; left for a season, it is a rebuild. That is the quiet case for treating artificial turf on concrete as a system rather than a sheet.<\/p>\n<h2 id=\"when-the-slab-is-not-worth-covering\">When the Slab Is Not Worth Covering<\/h2>\n<p>Honesty is a fixing method too. If more than a small area of the slab sounds hollow, or the cracking is structural, a concrete contractor is called before any turf is ordered. If water has nowhere to go and no economic fix exists, breaking the slab out is occasionally the honest answer. And a children&#8217;s fall zone does not start until the shock-pad budget exists.<\/p>\n<p>Per Pave-n-turf&#8217;s published guide, DIY materials for a 200-300 sq ft patio run $3-8 per sq ft. The range tracks turf quality and whether a pad is added. Per the same guide, a patio up to roughly 300 sq ft is a full weekend: 2-4 of prep, 1-3 of drainage and 2-3 of adhesive work. Per CHOICE, an artificial lawn costs roughly double a natural-turf installation. Per the recycler&#8217;s guide, used turf saves 50-75% against new, which is the salvage route for tight budgets.<\/p>\n<p>Walk, fix or walk away &#8211; those are the three verdicts a quoting contractor hands a client, and a slab audit is what earns the right to give one. The roll is the line the slab dimensions set, so match the <a href=\"https:\/\/www.relyirgrass.com\/artificial-grass-products\/artificial-grass-roll\/\">artificial grass roll specifications<\/a> to the surveyed area before committing. That discipline separates the projects that install artificial turf on concrete successfully from the ones that peel after the first storm.<\/p>\n<p><!-- relyirgate:C1 --><\/p>\n<h2 id=\"faq\">Frequently Asked Questions<\/h2>\n<p>The answers below close out the questions dealers hear most before quoting a slab conversion. Each one is answered the way we would brief a client who plans to install artificial turf on concrete. If your case sits outside them, send the slab dimensions before ordering anything.<\/p>\n<div class=\"faq-card\">\n<h3>Can you lay artificial turf straight on concrete without preparation?<\/h3>\n<p>No. Unprepared slabs pool water after the first rain, and trapped moisture breeds mold, a musty smell, bubbles and peeling edges. Concrete is non-porous, so a mid-slab puddle ends as odor and algae. Audit, drain, cushion and fix first.<\/p>\n<\/div>\n<div class=\"faq-card\">\n<h3>How do you stop artificial grass from smelling on concrete?<\/h3>\n<p>Treat odor as a drainage problem. Urine traps between turf and a non-porous slab and builds into ammonia, so the fix combines a drainage-cell air gap, regular enzymatic cleaners and an anti-microbial infill. Never an absorbent foam pad over a dog area.<\/p>\n<\/div>\n<div class=\"faq-card\">\n<h3>Will artificial grass damage a concrete slab?<\/h3>\n<p>No &#8211; the risk runs the other way. Pins never go into the slab, and the real threat is trapped water breeding mold and odor beneath the sheet, not damage to the concrete. A sound, drained slab comes through the conversion unchanged.<\/p>\n<\/div>\n<div class=\"faq-card\">\n<h3>How much height do turf and underlay add on a concrete slab?<\/h3>\n<p>Usually 30-45 mm or more &#8211; turf about 25 mm plus a 5-20 mm pad.
