Most people shopping for artificial turf focus on the green stuff — fiber height, color, softness, warranty. And those things matter. But the truth, from the installer side, is that the product is maybe 40% of what determines whether your install still looks great fifteen years from now.
The other 60% is the base.
The base is the layer between your native soil and the turf itself — usually 3-4 inches of crushed stone, graded for drainage, compacted properly. You never see it once the turf goes down. But it’s the single biggest predictor of whether your yard looks perfect in year ten or starts lifting, puddling, and rippling in year two.
Here’s what we actually do, and what to ask any installer who quotes you.
What a proper base looks like
Step 1: Excavate
We dig out 3 to 4 inches of existing sod and topsoil across the entire install area. Minimum.
Why it matters: Laying turf over thin soil or on top of existing sod traps organic material that decomposes, settles, and eventually leaves you with low spots. Anyone who skips this step is setting up a two-year install, not a fifteen-year one.
What to ask the installer: “How deep are you excavating before you bring in the base?” Answer should be 3-4 inches at minimum. Anything less is a shortcut.
Step 2: Graded crushed stone
We bring in a specific gradation of crushed stone — usually a mix of 3/4-inch and 1/4-inch with fines, sometimes called “Type 2” or “dense-graded aggregate.” This particular mix compacts into a solid, stable layer while still allowing water to pass through to the soil below.
Why it matters: The wrong stone — pea gravel, river rock, pure fines — either doesn’t compact or doesn’t drain. Either way, the install fails.
What to ask: “What stone are you using, and why?” If the answer is vague, they don’t know or don’t care.
Step 3: Compact in lifts
We spread the stone in layers (“lifts”) of maybe 1.5-2 inches, then compact each layer with a plate compactor before adding the next. This gets the base genuinely solid.
Why it matters: Dumping all the stone at once and compacting the top doesn’t actually compact the stuff underneath. You end up with a base that settles unevenly over the first year. That’s where bumps and low spots come from.
What to ask: “Do you compact in lifts?” If they say “we compact once at the end,” they are going to have a bumpy install in a year.
Step 4: Grade for drainage
Texas rains are real. A flat turf install on a flat base becomes a swimming pool in July. We grade the base to slope at about 1-2% toward a drainage path — usually the downhill side of the lot or an existing drain.
Why it matters: Turf itself drains, but if there’s nowhere for the water to go, it pools at the base layer. That trapped water degrades the backing over time, breeds mold in the infill, and smells terrible in hot weather.
What to ask: “Where does the water go?” The installer should have a clear answer about slope, direction, and any existing drainage they’re tying into.
Step 5: Weed barrier (maybe)
Some installers put a woven weed barrier between the base and the turf. Some don’t. Opinions vary.
Our take: A high-quality woven barrier (not the flimsy non-woven stuff) is a cheap insurance policy and adds about 2 cents per square foot. We use it on most installs.
What to ask: “Do you use a weed barrier? Which type?” If they don’t know the difference between woven and non-woven, they’re not thinking carefully about this.
The signs of a bad base (after the fact)
If you already have turf installed and are seeing any of these, the base was rushed:
- Visible bumps or low spots — uneven compaction
- Water pooling after rain — no drainage slope
- Fiber mat looking wavy — settling from inadequate compaction
- Smell coming from the yard in summer — moisture trapped in the base
- Seams lifting — edges not anchored to a solid base
Fixing a bad base after the fact means pulling up the turf and redoing the entire install. It’s not a small repair. That’s why doing it right the first time is the whole game.
Why most installers skip steps
The honest answer: because base work is time-consuming and invisible. A crew can lay turf over thin or uncompacted base in 40% less time. The homeowner doesn’t know the difference on handoff day. The difference shows up in year two or three, when the original installer is long gone.
If you’re comparing two quotes and one is significantly cheaper, the cheaper one is almost always cutting corners on base prep. The turf material is roughly the same wholesale cost across installers. Labor and materials for the base is where the variation hides.
The three-question quote sanity check
Revised from our pricing post, with base-prep specifics:
- “How deep are you excavating, what stone are you using, and are you compacting in lifts?” All three should have clear answers.
- “How are you handling drainage?” Should name a direction and a slope percentage.
- “What happens in year five if something settles?” A legitimate installer stands behind the install. We cover settling in year one as part of our installation warranty.
If any of those three questions draws a shrug, keep shopping.
