Slab Foundation Repair in New Braunfels, TX

New Braunfels Foundation Repair HQ has repaired slab-on-grade foundations across New Braunfels, Texas for over 18 years. Most homes here sit on a concrete slab poured directly on the ground, and the ground in question is the expansive clay of the Balcones Fault zone, soil that swells with every wet spell and shrinks through every drought. When that movement outpaces what the slab can flex with, a corner drops, brick cracks in a stair-step line, and doors stop closing. Our crew fixes it the way this soil demands: steel or concrete pressed piers driven to load-bearing strata, a controlled lift back toward level, and drainage correction so the clay under the footing stops cycling.

New Braunfels sits on the Balcones Fault, the boundary where Hill Country limestone gives way to the expansive clay of the prairie. On the clay side, the soil takes on water and swells, then gives it up through drought and shrinks, and a slab-on-grade foundation rides on top of that cycle. The edges of the slab dry out and rebound fastest, which is why settlement here so often shows up as a dropped corner or a sinking perimeter beam while the middle of the house stays put.

The repair is to take the slab's weight off the active clay entirely. Our crew installs pressed piers, sections of steel or concrete pushed into the ground hydraulically using the weight of the house itself, until each pier reaches load-bearing strata below the zone that swells and shrinks. Galvanised steel piers drive deepest and suit heavy masonry homes and deep-clay lots, while concrete pressed pilings are the economical choice where firm bearing sits closer to the surface. We tell you which your lot calls for after we measure it, not before.

Where the piers go depends on where the slab has dropped. Exterior piers are set from outside: we dig at the perimeter grade beam, drive the pier beneath it, and cap it with a steel bracket, with no need to enter the house. Interior piers handle settlement in the middle of the slab: we open a small section of the floor, drive the pier through it, and repour the concrete once the lift is done. With every pier seated, hydraulic jacks raise the slab back toward its original elevation in small, monitored increments, closing cracks as it comes up. When movement spans the whole footprint rather than one side, the job becomes leveling the entire house instead of a corner repair.

Piers stop the settlement; drainage keeps the surrounding clay calm. If a gutter dumps at the foundation or the yard grades toward the slab, we correct it as part of the repair so the soil around the new piers stops swinging from saturated to bone dry.
