Your concrete slab foundation is the backbone of your home. When it settles, shifts, or cracks, everything above it suffers; sticking doors, uneven floors, wall cracks, and structural stress that only gets worse with time.
VAN General Contracting specializes in slab foundation repair in San Antonio, using engineered steel pier systems to permanently stabilize your foundation, stop further movement, and restore your home’s safety and value.
Slab foundation repair is the process of stabilizing a concrete slab that has settled, shifted, or cracked, then restoring it to its proper level. In San Antonio, the cause is almost always the same: expansive clay soil that shrinks during drought and swells during heavy rain. Do this enough years in a row and even a solid slab starts to move unevenly.
The most effective fix for concrete slab foundation repair is driving steel piers down to stable soil, then using hydraulic pressure to lift the slab back toward its original elevation. It’s a permanent structural repair, not a patch job.
A full slab foundation repair in San Antonio means diagnosing the real cause of movement, not just patching the symptoms, so the fix holds for the life of your home.
We start by measuring floor elevations across the affected areas and documenting exactly where and how much the slab has settled. This mapping tells us where piers need to go and how many are required.
Every home sits on different soil, so every repair plan is different. We design pier placement around your home’s layout, soil conditions, and load points, not a one-size-fits-all pattern.
Our crew drives engineered steel piers through the slab and down into stable, load-bearing soil below the shifting clay layer, past the depth where San Antonio’s soil moves.
Using hydraulic equipment, we lift the settled sections of your slab back toward its original elevation, closing gaps, reducing cracks, and re-aligning doors and windows in the process.
Once the slab is stabilized, we address the cosmetic damage settlement caused: cracked flooring, drywall cracks, and gaps at the wall-to-ceiling line.
We verify stability across every repaired area and provide full documentation, including your transferable lifetime warranty, so you’re covered for as long as you own the home.
We inspect your foundation, measure elevations, find the cause of movement, and build a pier plan around your home and soil.
Steel Pier Installation Our crew drives engineered steel piers through the slab into stable load-bearing strata beneath the clay, the same approach used on commercial structures.
Common signs include wall cracks, uneven floors, sticking doors, and visible cracks along the slab edge. A free inspection will confirm whether repair is needed and what type.
Pier and slab repair involves installing steel piers beneath a settled concrete slab, then using hydraulic pressure to lift and re-stabilize it. It's the most permanent solution for foundation settlement in San Antonio's clay-heavy soils.
Cost depends on how many piers you need, how deep they go, and how much settlement there is. A free inspection gets you a real number, not a guess.
Most residential slab repairs are completed in one to two days, depending on the number of piers required and the extent of settlement.
Lifting the slab back toward original elevation often reduces or closes cracks and re-aligns door frames. Some cosmetic repair may still be needed after structural work is complete.
It depends on your policy and the cause of the damage. Sudden events may be covered; gradual settlement typically is not. We can help document the damage for your claim submission.
Yes. Our engineered pier systems include transferable warranty coverage, protection that stays with the home if you sell.
