Foundation repair, engineered to stay permanent.
GroundLock stabilizes Central Texas slab foundations with steel piers driven past the shifting clay to load-bearing strata — then protects them from the drainage and soil conditions that caused the movement. One focused specialty, done to an engineer’s spec.

Central Texas sits on highly expansive clay. It swells when wet and shrinks in drought, lifting and dropping foundations by inches across a single season. Surface fixes ride that same moving soil — which is why they don’t last.
Steel piers are different. They’re hydraulically driven through the active clay to a stable, load-bearing stratum and driven to refusal. Your home’s weight transfers onto the piers instead of the soil, so the slab stays put through every drought and downpour.
- Reach deeper than pressed-concrete piers — past the zone of seasonal movement
- Installed to a measured engineer’s specification, then re-surveyed
- Backed by a lifetime transferable warranty
Elevation survey
Map the slab to ±⅛ in and locate every drop.
