Why it's happening

Why Central Texas
slabs move.

It isn't bad construction — it's the ground itself. Three forces work your foundation loose, season after season.

02 / CAUSE
PI 40+

Expansive clay

Central Texas sits on highly plastic clay that swells when wet and shrinks when dry — heaving and dropping slabs by inches.

±4 in

Drought–rain swing

Brutal summer droughts then sudden downpours cycle the soil, working foundations loose season after season.

#1 cause

Poor drainage

Water pooling against the slab keeps the clay in constant motion. Grading and drains are how we keep the fix permanent.

03 / SYSTEM
How the fix works

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.

01

Elevation survey

We map your slab to ±⅛ inch and pinpoint exactly where it has dropped.

02

Drive steel piers

Galvanized steel piers are hydraulically driven through the clay to load-bearing strata — to refusal.

03

Lift & lock

The slab is raised back to level and its weight transferred onto the piers, not the soil.

04

Verify & warranty

We re-survey, document the lift, and back it with a lifetime transferable warranty.

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."

— Marisol T. · Schertz

"Got three bids. GroundLock was the only one who measured the elevation first instead of guessing. No surprises, no upsell."
