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.

Why steel piers

Built to bypass the soil that breaks slabs.

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

Questions

Foundation repair FAQs

What method does GroundLock use for slab foundation repair?
Galvanized steel piers, driven hydraulically through the active clay to load-bearing strata. Steel piers reach deeper than pressed-concrete piers and aren’t affected by the seasonal soil movement that causes slabs to fail. We don’t install concrete, pressed, or hybrid piers for slab repair.
How much does foundation repair cost in Central Texas?
Most steel-pier projects range from roughly $4,500 to $14,000 depending on the number of piers, access, and any drainage work needed. Every estimate starts with a free elevation survey, so the scope is measured rather than guessed. See our cost guide for detail.
Is the warranty really transferable?
Yes — GroundLock steel-pier stabilization carries a lifetime transferable warranty that passes to the next owner, which is a meaningful asset at resale.
Do I need drainage work too?
Often, yes. Because water and soil movement cause most slab failures, we’ll recommend drainage, grading, or erosion control where it’s needed to keep the repair permanent — never as upsell, always tied to protecting the foundation.
