Slab Foundation Repair Live Oak, TX.

What's actually happening under your slab

A concrete slab is a rigid plate. When one corner of soil dries out and settles while soil under a shaded flower bed stays moist, that plate has to bridge the difference, and it bends. Push it far enough and the concrete cracks through, door frames rack out of square, and windows start to bind. The clay around Live Oak's older residential lots is unusually good at creating those sharp moisture differences from one side of a house to the other.

A single mature oak or pecan within about fifteen feet of the perimeter beam can pull moisture out of the clay deeper than the soil normally dries on its own, scooping a settlement bowl under that part of the slab. Leaking supply or drain lines do the opposite, keeping one zone swollen while the rest of the lot bakes. That's why so much Live Oak movement shows up at one corner rather than evenly across the foundation.

Many of the slabs we see here were poured during the building booms of the 1970s and '80s, sitting right in the active layer. The tell is timing: cracks that widen in late summer and ease back after the fall rains are riding the clay. Cracks that keep growing without that seasonal reversal are settling on a load you can't water away, and those are the ones piers are built for.

Signs it's worth a measured look

Any one of these can be benign on its own. Two or three together, especially on the same side of the house, are worth an elevation survey:

• Interior doors that drag or won't latch, particularly down a single hallway
• Stair-step cracks stepping down through brick mortar joints near a corner
• Gaps opening between the baseboard and the floor, or trim pulling off the ceiling
• Drywall cracks fanning diagonally from the corners of doors and windows
• Cracks in the slab itself or across the garage floor
• Floors that feel sloped or bouncy in one part of the house

How we measure, plan, and lift

Every Live Oak project opens with a free elevation survey accurate to ±0.01 in. (1/64 in.) taken across every reachable interior and perimeter point. That turns into a contour map of your slab's real shape, which separates true structural settlement from the harmless surface variation every slab has. You get a written, engineer-backed plan that names the pier count, target depths, and the order they'll be driven and loaded, sequence affects the result, so it isn't left to chance.

Galvanized steel piers go in hydraulically, advancing through the active clay and into load-bearing strata well below it. Because each pier is driven under your home's actual weight rather than a test load, the crew confirms refusal on competent material in real time, pier by pier. Depths here vary with how deep the active soil runs, often 10 to 25-plus feet, rather than a fixed number.

Lifting is the careful part. A hydraulic manifold raises multiple pier heads together so the slab comes up evenly instead of pivoting on one high point. Tile, partitions, and plumbing penetrations all limit how much correction is wise in a single session, so sometimes the right call is incremental lift with a settling period. We re-survey and document the final numbers before leaving. Most homes stay occupied throughout. Typical projects land between $4,500 and $14,000, financing is available, and the lifetime warranty transfers with the property if you sell.
