Three proprietary pier systems engineered for North Texas clay soils. Every system backed by a free lifetime transferable warranty.
Foundation piers are structural supports driven into the ground beneath your home to stabilize and lift a settling foundation. In DFW, three types are commonly used:
The most common repair method in DFW. High-strength concrete cylinders are hydraulically pressed into the soil beneath your foundation. Affordable, proven, and effective for moderate depth needs.
Steel pipe sections driven deep into the ground — often 20+ feet — until they reach bedrock or a stable soil layer. The go-to solution for deep soil movement and heavy structures.
Steel starter sections push past tough upper soil layers, then concrete cylinders finish the job. Balances penetrating power of steel with load-bearing surface area of concrete.
Stratum offers three foundation pier systems for Dallas-Fort Worth homes: the ST1 (concrete pressed piers, most affordable), ST3 (hybrid steel + concrete, 50% deeper), and ST10 (deep steel + concrete, 100% deeper). All include free lifetime transferable warranties. A free inspection determines which system your home needs.
Why does this matter in DFW? North Texas sits on expansive montmorillonite clay. This clay absorbs water and swells during wet seasons, then shrinks and cracks during dry spells. That constant movement pushes and pulls your foundation. The right pier type — driven to the right depth — stops that cycle from damaging your home.

DFW’s expansive clay soil doesn’t just sit still. It swells when it absorbs moisture and shrinks as it dries out. This seasonal cycle creates what engineers call the “active zone” — the upper layer of soil that’s constantly moving.
Shallow piers that only reach the active zone are still exposed to that movement. Over time, the soil shifts around them and your foundation problems come back.
Deeper piers reach below the active zone into stable soil or bedrock. The deeper a pier goes, the more friction it generates against the surrounding earth, and the more structural support it provides. That’s exactly why Stratum engineered three depth tiers: so your home gets piers that reach stable ground, regardless of how deep that ground is on your specific property.
This is also why a professional inspection matters. Soil conditions vary across DFW — a home in McKinney may sit on a different clay profile than one in Fort Worth or Dallas. The right system for your home depends on what’s happening beneath it.

Choosing between the ST1, ST3, and ST10 depends on several factors specific to your property:
You don’t have to figure this out on your own. Stratum’s NFRA-certified inspectors evaluate your foundation, assess soil conditions, and recommend the right system — at no cost to you.
