Artificial Turf: A Base Job With a Surface On Top

What failing turf looks like, and which layer it points at

Turf failures are as diagnostic as paver failures, and for the same reason: the surface is flexible and it reports what the base beneath it is doing.

• Water standing on the surface after rain — either the base is not draining, the fall is wrong, or the water arriving exceeds what the design accounted for. The turf backing is usually not the culprit.
• A dished or dipped area in the middle of the field — the base settled. Uneven compaction, one deep lift instead of several, or fill underneath that was never compacted back.
• Wrinkles or ripples that appear months after installation — the material was not stretched and secured adequately, or it has moved with temperature. Synthetic backing expands and contracts with heat.
• Seams that have opened or lifted — seam preparation and fixing. The most visible workmanship failure and the hardest to hide afterwards.
• Edges lifting or curling away from a hard edge — perimeter fixing or edge restraint, the same category of failure as a patio spreading at the edge.
• Blades lying flat and matted, especially on paths of travel — infill depleted or never adequate. Infill is what holds the fibre upright under traffic.
• Persistent odour where pets use it — drainage through the system, and the infill choice. The system has to let liquid pass and be rinsed through rather than holding it at the surface.
• The surface is uncomfortably hot in the afternoon — not a defect and not fixable by the installer. It is a property of synthetic surfaces in direct sun and it is worth knowing before rather than after.
• Weeds appearing through seams and edges — usually windblown seed germinating in the infill, not growth from underneath. It is a maintenance item, and the point is that turf is low-maintenance rather than no-maintenance.

Turf, and the four things it gets compared against

Artificial turf is normally quoted against one alternative that has been chosen for it. These are the real options, and they answer different questions.

What a contractor should look at before quoting turf

A turf quote produced from a square footage and a product name has priced the surface. These are the things that decide the installation.

• Where water currently goes after rain, and where it will go once the surface changes. This is the first question, not the last one.
• The soil. A parcel-level lookup of the mapped soil, its drainage class, its hydrologic soil group and its shrink-swell potential — free, and the drainage class and shrink-swell rating both matter under a base.
• The existing grade, how much has to be cut or filled, and what the finished level has to meet — a patio, a threshold, a driveway edge.
• How the area is used. Dogs, children, heavy foot traffic and furniture all change the specification, and pet use in particular changes the drainage and infill conversation.
• Sun exposure. A south-facing area in full afternoon sun behaves differently from a shaded courtyard, both thermally and for how the material ages.
• What is being removed and where it goes. Stripping an existing lawn produces a substantial volume of material that leaves by truck.
• Mature tree roots within the footprint. Excavating a base over structural roots can damage a tree slowly enough that nobody connects the two.
• Whether a water utility rebate programme applies here, and what it will and will not pay for. Some programmes exclude synthetic turf entirely and pay only for planted conversions.
• Homeowners association covenants and any local ordinance on synthetic turf. Some prohibit it, some restrict it to rear yards, and some specify products.
• Utility locates. In the United States, calling 811 before digging is free and in most states it is required.

What the work involves

Eight steps, and the first five are the ones that decide the outcome. By the time the turf is rolled out, the installation has already succeeded or failed.

1. 01

   Removal and excavation

   Stripping the existing surface and excavating to the depth of the base plus the turf. Like any hardscape excavation, the spoil volume is larger than it looks and it has to leave the property.

2. 02

   Grading and the drainage design

   Establishing the fall and deciding where water goes. Surface fall away from buildings, and where the ground below does not drain, a designed subsurface path rather than an assumption that the base will cope.

3. 03

   Compacting the subgrade

   The excavated ground is compacted before any stone goes on it. This is the same step a paver patio takes for the same reason: a base built on loose ground settles regardless of how well the base itself is compacted. ICPI specifies 98% of standard Proctor density, ASTM D698 for pedestrian paving, which is the nearest published analogue to this work.

4. 04

   Building the base in lifts

   Aggregate placed and compacted in layers rather than in one dump. ICPI’s paving guidance places base in lifts of 4 to 6 inches, each compacted before the next, and the logic transfers directly: aggregate compacts from the top, so a deep single lift is not a compacted base.

5. 05

   The levelling course and weed barrier

   A finer compacted layer screeded flat, because every irregularity in it reads through the turf exactly as an uneven base reads through pavers, and a separation or weed layer where the system uses one.

6. 06

   Laying, seaming and stretching

   Rolling the material out, letting it relax, aligning the fibre direction consistently across every piece, then seaming and stretching before fixing. Seams and fibre direction are the two things that make an installation look deliberate or look patched.

7. 07

   Perimeter fixing and edges

   Securing every edge against a restraint or into the base. Edges that are not restrained lift, curl and catch, and it is the same failure mode as a patio spreading at its perimeter.

8. 08

   Infill and grooming

   Infill brushed into the pile at the specified rate, then the surface groomed to stand the fibre up. Infill is not decorative: it ballasts the material, holds the blades upright and affects how the surface handles liquid.

The water argument, stated honestly

EPA WaterSense publishes figures about outdoor household water use. They are the strongest sourced numbers in this conversation, and they are about irrigation rather than about turf. Read them for what they say.

What belongs in the written scope for turf

Read a turf quote the way you would read a paving quote, because it is one. The product name, the pile height and the colour are the part you can compare on a website; the list below is the part that decides whether the surface is flat and dry in five years, and it is invisible the day it is finished.

• Excavation depth, in inches, and what happens to the spoil.
• Subgrade compaction, stated as a method and a target, exactly as a paving scope states it.
• Base material and compacted thickness, in inches, and the lift thickness it is placed in.
• The levelling course: material and thickness, screeded flat. Every dip in it will be visible through the surface.
• Fall, as a percentage and a direction, away from any building.
• The drainage path: where water goes once it passes through the surface, and whether any subsurface collection and outlet is included. On a site that does not drain, this is the line that matters most.
• The turf specification: product, pile height, backing type and whether it is a perforated or fully permeable backing.
• Infill: the material, named, and the application rate. "Infill included" is not a specification.
• Seaming method, and confirmation that fibre direction is consistent across all pieces.
• Perimeter fixing and edge restraint: what the edges are secured to and how.
• Weed barrier or separation layer, where the system uses one.
• The warranty: separately for the product and for the workmanship, with the durations and exclusions stated. Fade, wear, seam failure and settlement are frequently covered by different clauses or by none.
• Maintenance expected of you: grooming, rinsing, infill top-up, and how often.
• Who calls 811, and when.

The buried-work argument on the base specification applies to this work in full. The published numbers there are ICPI’s, written for interlocking concrete pavement rather than for turf, and we cite them as the nearest verified analogue rather than as a turf standard — no comparable published figure for synthetic turf base construction was available to us.

What moves the price

Turf is priced per square foot, which hides the fact that the excavation, the base and the disposal are a large share of the job and have nothing to do with which product you chose.

HyreYard publishes no average price for this work and holds no dataset of landscaping invoices. Access, soil, grade, regional labour and material availability move the number far enough that a single figure would mislead more than it helped.

What to ask before you sign

• How deep is the excavation, how thick is the compacted base, and in what lift thickness is it placed?
• How is the subgrade compacted before the base goes down, and to what standard?
• What fall are you building in, as a percentage and in which direction?
• Where does water go once it passes through the turf — is there a designed subsurface path and an outlet, or are you relying on the ground below?
• What infill, specifically, and at what application rate?
• How are the seams made, and will fibre direction be consistent across every piece?
• What are the edges fixed to, and is any edge restraint included?
• What does the product warranty cover, for how long, and what does the workmanship warranty cover separately?
• Does fade, wear, seam failure or settlement void anything, and what maintenance am I required to perform to keep the warranty valid?
• Is this area eligible for a water utility rebate here, and does that programme cover synthetic turf or only planted conversions?
• Does the local ordinance or the homeowners association permit synthetic turf in this part of the property?

The full ten-point checklist is on choosing a landscaping company, and the lines a comparable bid contains are on reading a landscaping estimate.

What to have ready

• Photograph the area after heavy rain before anyone visits. Where water stands now is where the drainage design has to start, and it is invisible on a dry day.
• Look your address up on the USDA Web Soil Survey and note the drainage class and shrink-swell rating.
• Stand in the area in mid-afternoon in summer and note how much direct sun it gets. Synthetic surfaces in full sun get hot, and that is easier to evaluate before installation than after.
• Check your water utility for a rebate programme and read what it covers. Several fund planted conversions and specifically exclude synthetic turf.
• Check homeowners association covenants and any local ordinance. Some restrict or prohibit synthetic turf, and some restrict it to rear yards.
• Work out honestly how the area is used: dogs, children, furniture, foot traffic. Pet use in particular changes the drainage and infill specification.
• Get a quote for fixing the irrigation and a quote for the turf. If the argument for turf is water, the efficient-lawn option deserves a real number rather than a dismissal.
• Find your downspouts and note where they discharge, because a new surface changes what happens to that water.

Where this goes wrong

Common questions

Does artificial turf save water?

Removing irrigated lawn removes the irrigation that went with it, so directionally yes — but we are not going to publish a number, because the honest answer depends entirely on what you were irrigating, how efficiently and in what climate, and we hold no dataset of turf installations. What is sourced is the size of the problem: EPA WaterSense reports that American households use “nearly 8 billion gallons of water each day, mainly for landscape irrigation” and that “as much as 50 percent of this water is wasted due to overwatering caused by inefficiencies in irrigation methods and systems” Read that second figure carefully, because it changes the decision: a large share of outdoor water use is lost to inefficiency rather than to lawns existing. A properly scheduled controller and a repaired system address a meaningful part of it without removing anything, which makes the efficient-lawn option a real alternative that deserves a quote of its own rather than a rhetorical dismissal.

How long does artificial turf last?

We do not publish a figure, because we have no sourced one and the numbers circulating in the industry are manufacturer marketing rather than independent measurement. What we will say is that the cycle is real: turf wears where it is walked, it fades in sun, the fibre lies down in traffic lanes, and at some point it is removed and replaced. That has two consequences worth planning for. First, any cost comparison against a living lawn has to account for replacement or it is comparing a one-time cost to an ongoing one. Second, ask what happens to the material at the end — whether the installer takes it back, whether it is recyclable where you live, or whether it goes to landfill. That is a reasonable question and the answer varies by region.

Does artificial turf get hot?

Yes, in direct sun, and noticeably hotter than living grass, which cools itself by transpiring. We are not going to publish a temperature figure because we hold no measured data and the numbers vary enormously with sun angle, air temperature, product and infill. What matters practically is that it is a property of the material rather than an installation defect, no installer can remove it, and it is worth evaluating before you buy rather than after. If the area is south-facing and used in the afternoon by children or dogs, stand on an installed piece in similar conditions before deciding. Shade, whether from a tree, a structure or the orientation of the space, changes the experience substantially.

What is infill and do I need it?

Infill is granular material brushed down into the pile between the fibres, and it does three jobs: it ballasts the turf so it stays where it was fixed, it supports the blades so they stand upright rather than matting under traffic, and depending on the material it affects how liquid moves through the system — which matters a great deal where pets use the surface. It is not optional on a normal installation and it is not a detail. It is also the line most frequently left unnamed in a quote, which conveniently makes two quotes impossible to compare. Ask for the material by name and the application rate, and ask how often it needs topping up, because infill migrates and depletes over time.

Is the base really that important?

It is the job. Artificial turf is a flexible surface, which means it reports faithfully everything the layers below it do: a dished area in the base shows through as a dip, an uneven levelling course shows through as a ripple, and a base with nowhere to send water shows up as ponding. This is exactly the same relationship a paver patio has with its base, and ICPI states the principle directly for paving — unevenness in the bedding layer reflects through to the surface over time. We cite ICPI’s published figures on this page as the nearest verified analogue, not as a synthetic turf standard; no comparable published specification for turf base construction was available to us. The practical test stands regardless: ask for excavation depth, subgrade compaction, base thickness, lift thickness and fall, in writing, and compare quotes on those.

Can I get a rebate for replacing my lawn?

Sometimes, and the terms are entirely local. Turf replacement rebates are run by individual water utilities and water districts rather than nationally, and they differ on almost every variable that matters: the rate per square foot, the maximum area, whether you have to apply and be inspected before starting, what the replacement has to consist of, and critically whether synthetic turf qualifies at all. A number of programmes are written for planted, low-water conversions and specifically exclude synthetic surfaces, on the grounds that the aim is living landscape rather than an impervious one. Check your own utility before you sign anything, and run the arithmetic on the turf rebate tool against what we could verify on turf rebate programs.

What maintenance does artificial turf need?

Less than a lawn, and more than nothing, and the gap between "low-maintenance" and "maintenance-free" is where most disappointment lives. Expect to clear leaves and debris so the surface drains and the fibre is not smothered, brush or groom the pile to stand it up in traffic areas, top up infill as it depletes and migrates, rinse the surface where pets use it, and remove weeds that germinate from windblown seed in the infill rather than from underneath. None of that is onerous, but it is a routine, and a system that is never rinsed or groomed ages faster and looks it. Ask the installer what they expect of you and how often, and check whether any of it is a condition of the warranty.

Is artificial turf impervious?

Not in the sense a patio is — the backing is designed to let water through, either through perforations or as a fully permeable construction — but the question that matters is what happens underneath. Water that passes through the surface arrives at a compacted aggregate base on a compacted subgrade, and if that ground does not accept water, the water has to be led somewhere by design. On a free-draining soil that is often straightforward. On a slow-draining one it is a drainage job, with a collection path and an outlet, priced as part of the installation. This is worth settling early because the EPA is describing the same mechanism when it notes that buildings, pavement and compacted landscapes do not allow rain and snow melt to soak into the ground, which greatly increases the volume and velocity of stormwater runoff. A compacted base is a compacted landscape, whatever is lying on top of it.
