One specialty. Done permanently.
GroundLock is a Central Texas foundation-repair company focused on a single thing: stabilizing slab foundations with engineer-backed steel piers — and protecting them from the drainage, soil, and moisture that cause movement.
We don’t do a little of everything. We do foundations — and we do them to last.
Why steel piers only
Central Texas sits on expansive clay that swells and shrinks by inches across a season. Surface fixes ride that movement. Steel piers driven to load-bearing strata don’t. That focus is why slab repair is the only foundation method we install — no concrete, pressed, or hybrid piers, and no pier-and-beam as a headline service.
Engineer-backed, start to finish
Every project begins with a measured elevation survey and is designed to a structural engineer’s specification. We log drive force at each pier, re-survey the lift, and close out with documentation lenders, buyers, and insurers accept.
Built around the corridor
From far South San Antonio to far North Austin, we serve 12 counties and 50+ cities. Local crews know the soils street by street — Houston Black clay on the South Side, karst limestone in the Hill Country, Blackland prairie along I-35.
