Why Central Texas
slabs move.
It isn't bad construction — it's the ground itself. Three forces work your foundation loose, season after season.
Expansive clay
Central Texas sits on highly plastic clay that swells when wet and shrinks when dry — heaving and dropping slabs by inches.
Drought–rain swing
Brutal summer droughts then sudden downpours cycle the soil, working foundations loose season after season.
Poor drainage
Water pooling against the slab keeps the clay in constant motion. Grading and drains are how we keep the fix permanent.
Steel piers lock
your slab to
bedrock.
Surface fixes ride the same moving clay that broke your foundation. We bypass it entirely — anchoring to the stable stratum below.
Elevation survey
We map your slab to ±⅛ inch and pinpoint exactly where it has dropped.
Drive steel piers
Galvanized steel piers are hydraulically driven through the clay to load-bearing strata — to refusal.
Lift & lock
The slab is raised back to level and its weight transferred onto the piers, not the soil.
Verify & warranty
We re-survey, document the lift, and back it with a lifetime transferable warranty.
Engineered to
outlast the soil.
Engineer-backed repairs
Every project is designed to a third-party structural engineer's specification and closed out with a stamped report — the documentation lenders, buyers, and insurers ask for.

"They drove fourteen steel piers and re-leveled our 1978 slab in two days. Doors close again. The engineer's report sealed our home sale."
"Got three bids. GroundLock was the only one who measured the elevation first instead of guessing. No surprises, no upsell."
