Expert Slab-on-Grade Foundation Repair

Slab-on-grade foundations are poured directly on the ground and are common in newer homes across the greater San Antonio area. When soil movement, poor drainage, or plumbing leaks shift the slab, you get cracks, uneven floors, and sticking doors.

Sage FX corrects slab foundations with deep steel piers and precision leveling tailored to your home and local soil conditions. Our certified technicians address the root cause — not just the symptoms — for an effective, long-lasting fix.

Every slab repair is backed by a lifetime transferable warranty, and we offer flexible payment plans to keep the work within reach.

Slab Foundation Repair — FAQ

The usual culprits are expansive clay soil that swells and shrinks, poor drainage around the home, plumbing leaks under the slab, and original construction issues. We identify which one is affecting your home.
For most slab foundations, steel piers driven to load-bearing strata give the deepest, most reliable support. We recommend the right method for your specific home after inspecting it.
Some repairs require accessing the slab, but our crews repair and finish any concrete afterward — often you can barely tell we were there.
It depends on the number of piers and the extent of movement. Your free inspection includes a clear written estimate so there are no surprises.
