When most people think about artificial turf installation, they think about the grass. The blade shape, the color, the pile height. Maybe the infill.
Almost nobody asks about the base. And that is exactly where most installs either succeed for 15 to 20 years — or start failing within five.
At LBK Turf Guys, the base material we use is one of the most deliberate decisions we make on every job. We use crushed-washed limestone — what we call the True Drain base system — instead of the decomposed granite that most other installers default to. This post explains why, and why it specifically matters for Lubbock and West Texas soil conditions.
If you are comparing quotes and trying to understand why they are different, this is worth reading before you decide.
What the Base Actually Does — and Why It Is the Most Important Part of the Install
The turf you see is only part of the system. Underneath it is a layered structure that determines how well the whole installation drains, how stable it stays over time, and how the surface feels and performs after years of use.
A standard residential turf install stack looks like this from bottom to top:
- Native soil — compacted and graded
- Base material layer — the True Drain crushed limestone, or in other installs, decomposed granite or crushed rock
- Weed barrier fabric
- Turf product
- Infill — silica sand, pet infill, or heat-reduction infill depending on the application
The base layer does three things: it provides a stable, level platform for the turf to lay flat on; it manages drainage so water moves through quickly rather than pooling; and it resists the movement and compaction that comes from foot traffic, weather cycles, and time.
In a mild climate with sandy, well-draining soil, almost any base material handles those three jobs adequately. Lubbock is not that climate.
Landin Terry says: The base is the part of the install you never see after day one. But it is the part that determines whether you are calling us back in five years because something shifted or pooled — or whether your yard looks exactly the same in fifteen years as it did the day we finished.
What Makes Lubbock Different: Caliche, Dust, and Freeze-Thaw
Lubbock soil presents three challenges that make base material selection more consequential than it is in most markets.
Caliche
Caliche is a hardened calcium carbonate layer that forms naturally in arid and semi-arid soils — and West Texas has a lot of it. Depending on the property, caliche can sit anywhere from a few inches to a foot or more below the surface. It is dense, it does not drain well, and it does not break down easily.
When turf is installed over improperly addressed caliche, water that drains through the turf and base material hits the caliche layer and has nowhere to go. It pools at the interface between the base and the caliche, creating soggy areas, accelerating base material degradation, and in worst-case scenarios causing the base layer to shift or heave.
The True Drain system accounts for caliche depth during site assessment and adjusts excavation and base preparation accordingly. We are not just dropping material on top of whatever is there.
Lubbock Dust
West Texas produces some of the most significant dust events in the continental United States. Haboobs — large wall-dust storms driven by thunderstorm outflows — can deposit significant material across an entire yard in a single event. Even on calm days, the prevailing southwest winds carry fine particulate that settles into everything.
Decomposed granite is particularly vulnerable to this. DG base material contains fine particles of its own — that is the nature of the material. When Lubbock dust combines with DG fines and works down through the turf and infill layer into the base, the result is a gradual densification that reduces drainage over time. The base that drained well in year one drains progressively slower by year five.
Crushed-washed limestone is processed to remove fines before installation. The angular particle structure creates and maintains open void space that resists clogging even as dust accumulates in the surface layers above it.
Freeze-Thaw Cycles
Lubbock averages around 40 freeze days per year and experienced a record-breaking extended freeze during Winter Storm Uri in February 2021. Freeze-thaw cycles affect base materials differently depending on their particle size, gradation, and moisture content.
Decomposed granite with fine particles is more susceptible to frost heave — the process where water freezes in soil pores and expands, displacing material upward. In a base layer, this means edges can lift, seams can open, and the flat surface the turf was originally laid on becomes subtly uneven over time.
The angular, washed structure of crushed limestone drains water out of the base more completely before freeze events, reducing the moisture available for frost heave. It also holds its structure better under the expansion and contraction cycles that come with Lubbock’s wide temperature swings.
Worth knowing: Winter Storm Uri was the most significant test of turf installations across the region. The installs that held up best had proper base drainage — water that could not exit the base before the freeze caused the most damage. This shaped how we approach base prep on every job since.
True Drain vs. Decomposed Granite: Head-to-Head
Here is a direct comparison across the factors that matter most in a Lubbock installation:
| Category | True Drain (Crushed-Washed Limestone) | Standard DG (Decomposed Granite) |
| Drainage rate | Fast — open angular structure stays clear long-term | Fines compact over time, slowing drainage |
| Dust interaction | Does not contribute fine particles | DG fines migrate up into infill layer |
| Caliche compatibility | Layers cleanly over caliche without bonding | Can bind with caliche, creating hard pan |
| Freeze-thaw performance | Holds structure through freeze-thaw cycles | Fines can heave and shift under freeze-thaw |
| Long-term stability | Maintains drainage performance 15-20 years | Compaction increases over time |
| Edge stability (PFS Board) | Clean, stable platform for PFS Board edge | Soft or variable surface under edging |
| Wind uplift resistance | Dense, stable — resists wind-driven displacement | Lighter fines can migrate under wind load |
| Cost | Moderate premium over standard DG | Lower upfront material cost |
The one area where DG has an advantage is upfront material cost — it is cheaper to source. That is why most installers default to it. But the performance gap in Lubbock’s specific conditions means the savings at install time often show up as problems and repair costs later.
The PFS Board Connection: Why the Edge System Depends on the Base
LBK Turf Guys uses PFS Board composite edging on every install. PFS Board outperforms wood, metal bender board, and most polymer alternatives in longevity and wind resistance. But its performance depends on the base it is seated in.
Edging is only as stable as the material supporting it. A DG base that compacts unevenly over time creates a variable surface under the edging — leading to the subtle shifts, pops, and lifted corners that are the most common cosmetic failure in turf installations.
Crushed-washed limestone compacts to a stable, consistent density that provides a uniform platform for PFS Board. Combined with proper mechanical fastening, the edge system maintains its line and height through Lubbock’s wind load, temperature swings, and the freeze-thaw cycles that cause most edging failures in other installs.
When a homeowner calls us years after an installation because their edging is lifting, the root cause is almost always the base — not the edging product itself.
The Complete LBK Install Process: What Happens Under Your Turf
For homeowners who want to understand the full picture, here is how a standard LBK Turf Guys residential installation proceeds from ground to finish:
| Step | Phase | What LBK Does |
| 1 | Site assessment | Evaluate existing soil, caliche depth, drainage flow direction, and any grade issues that affect water runoff |
| 2 | Excavation | Remove existing sod, rock, or base material to the correct depth — typically 3 to 4 inches for residential; deeper for problem caliche areas |
| 3 | Caliche treatment | Where hard caliche is present, mechanically break or address the layer to prevent water pooling above it |
| 4 | True Drain base install | Crushed-washed limestone compacted to grade — the stable, fast-draining foundation layer unique to LBK installs |
| 5 | PFS Board edging | Composite edging set and secured around the perimeter before turf goes down — ensures clean edges that hold under West Texas wind |
| 6 | Weed barrier | Commercial-grade weed barrier laid over the base |
| 7 | Turf installation | Turf rolled out, cut to shape, seamed where required, and secured — seam direction planned to minimize visibility |
| 8 | Infill application | Infill applied by spreader and worked into the blades — product selected based on use case |
| 9 | Power brush and inspection | Final power brush to stand blades upright, even out infill, and inspect seams, edges, and drainage before handoff |
The True Drain base is Step 4 in that sequence — but the decisions made in Steps 1 through 3 determine how well Step 4 performs. Site assessment and caliche treatment are not steps that can be skipped to reduce cost without real consequences.
Why This Matters When You Are Comparing Quotes
If you have gotten multiple quotes for artificial turf installation in Lubbock, you have probably noticed price variation. Some of that reflects different turf products. Some reflects labor rates and company overhead. But a significant portion of it reflects base material and preparation decisions that never get explicitly named in the quote.
Questions worth asking any installer you are evaluating:
- What base material do you use, and what grade or specification?
- How do you handle caliche if you hit it during excavation?
- What is your drainage rate specification for the finished base layer?
- What edging system do you use, and how is it secured?
- What does your warranty cover, and does it include drainage or base performance?
Most installers will not have detailed answers to those questions — because the base decision was made on cost, not performance. The base is where an honest installer separates themselves from a cheap one. We would rather explain our base system upfront than have a homeowner call us in year four wondering why their yard is not draining the way it should.
On cost: The True Drain base adds modest cost compared to standard DG — it is a better material and it takes more preparation to install correctly. We build it into every quote transparently. For a full breakdown of what goes into LBK installed pricing, see our cost guide.
Frequently Asked Questions
Can I request the True Drain base system specifically when I get a quote?
Yes — and you should. Every LBK Turf Guys install uses the True Drain crushed-washed limestone base as standard. When comparing quotes from other installers, ask specifically what base material they use and what their specification is. The answer tells you a lot about how they approach the rest of the install.
How deep is the base layer in a typical Lubbock install?
A standard residential install uses 3 to 4 inches of compacted base material. Properties with significant caliche issues, drainage challenges, or heavy use areas may require deeper excavation and a thicker base layer. We assess depth during the site visit, not after excavation starts.
What happens to drainage over time with a crushed-limestone base?
A properly installed True Drain base maintains effective drainage throughout the life of the turf product — typically 15 to 20 years. The open void structure resists compaction better than DG, and the washed nature of the material means it does not contribute the fines that cause progressive clogging. Routine surface maintenance keeps the surface layers clear and drainage performing as designed.
Does the base material affect how the turf feels underfoot?
Yes — a well-compacted, consistent base produces a firm, even surface that feels natural underfoot and does not develop soft spots or subtle unevenness over time. Variable or poorly compacted base material tends to show through the turf as irregular surface texture, especially in high-traffic areas.
What if my yard already has an old turf install with a DG base that is draining poorly?
Poor drainage on an existing install usually means the base has compacted, clogged, or was underprepared from the start. In most cases, remediation requires removing the existing turf, regrading and replacing the base material, and reinstalling. It is not a small job — which is why getting the base right the first time is worth the upfront investment. Call us and we will take a look at what is going on.
