Foundation repair and waterproofing
Slab and pier repair, drainage correction, and waterproofing built around how Bexar County clay actually behaves.
The soil is the problem, and it is fixable
San Antonio sits largely on expansive clay. Clay takes on water and swells; it dries out and shrinks. Across a Texas summer that cycle can move a slab enough to crack drywall, jam doors, and separate brick. It is not a defect in your house so much as the ground doing what this ground does.
Which means the repair that lasts is the one that addresses moisture, not just elevation. Lifting a slab back to level and leaving the drainage that caused the movement gets you the same call in three years. We look at grading, gutters and downspout discharge, irrigation placement, and where water actually sits after a storm before we talk about piers.
What an honest foundation assessment looks like
Elevation readings across the slab, documented, so there is a number rather than an impression. Photographs of the crack pattern, because the pattern tells you whether the movement is heave or settlement and those have opposite fixes. And a plain answer about whether the movement is active or historic — a house that moved fifteen years ago and stopped does not need piers.
Foundation repair is the corner of this trade with the most aggressive sales practices in it. If somebody quotes you a pier count before taking elevations, that number came from somewhere other than your house.

Common questions
- Why do so many San Antonio homes have foundation problems?
- Expansive clay soil. It swells when wet and shrinks when dry, and the seasonal swing here is large enough to move a slab measurably. Homes built before modern soil preparation practices, and homes with poor drainage or large trees close to the foundation, feel it most.
- Are cracks in my drywall a foundation problem?
- Sometimes. Hairline cracks above doors and windows are common and often cosmetic. Cracks that are wider at one end, that reopen after being patched, that run diagonally from window corners, or that come with doors binding and floors sloping are worth an elevation survey. That survey is how you tell the difference between a house that settled once and a house that is still moving.
- Will fixing drainage alone solve it?
- Sometimes, and that is worth finding out before you spend on piers. If moisture is cycling because water pools against the slab or a downspout dumps at the corner, stabilizing the moisture can stop the movement. We would rather sell you a drainage correction that works than a pier system you did not need.
- Do foundation repairs come with a warranty?
- Ours are covered by the warranty stated in your signed contract, and manufacturer warranties on pier systems pass through to you under the manufacturer's own terms. Ask for both in writing — from us or from anyone else you are considering.
