What it is, and why it matters.
Slab foundations fail when soil moves under or around them: expansive clay, washed-out fill, tree roots or leaking pipes. The signs are cracked tile, sloping floors, doors that stick and diagonal cracks above doors and windows.
Repair starts with a floor elevation survey, then uses slab piers, foam or perimeter piers to stabilize and lift the foundation, with drainage and plumbing checks to stop the cause.
Four things done right.
Elevation survey
We map the floor so repairs target the real low spots.
Piers and foam
Support goes where the soil failed.
Plumbing checks
Leaks can wash out soil, so we rule them out.
Water control
Drainage keeps clay stable.

Slab Foundation Repair: common questions
What causes slab foundations to crack?
Expansive clay, soil washout, leaking pipes, tree roots and poor drainage all move the soil under a slab. Slabs can also crack from curing shrinkage that is not structural.
Can a slab foundation be lifted?
Often yes, using interior or exterior piers or foam. How much it lifts depends on its condition and the cause.
