Foundation Settlement Repair Selma, TX.

Why Selma slabs drop unevenly

Most of Selma's developed land sits over the Cibolo Creek watershed, where Houston Black clay dominates the soil profile. That clay carries a plasticity index in the 40-to-60 range, which is a technical way of saying it swells and shrinks a lot as its moisture content moves between the wet springs and the baked-dry summers this part of Bexar County is known for.

When the clay dries and pulls back from the underside of your foundation, the slab loses the bearing support it was poured to sit on. It rarely settles evenly. One corner drops while another holds, and that differential movement is what tears brick veneer, splits drywall at the door frames, and leaves floors sloping toward the low side. The active zone here runs roughly 8 to 15 feet deep, shifting with lot grading, tree cover, and how close you are to the creek floodplain.

A foundation built on shallow footings never really gets to rest. The soil contracts in July, swells again after a wet winter, and the concrete flexes with every cycle. The only durable answer is to carry the load past that restless layer to strata that stay put year-round.

How the repair anchors below the clay

With the survey in hand, we know whether the pattern points to isolated pier failure, edge desiccation along a sun-exposed wall, or a broader moisture imbalance across the lot. That distinction changes where the piers go and how deep they need to reach.

We hydraulically drive galvanized steel piers through the active clay until they hit competent load-bearing strata, then apply controlled pressure to lift and re-level the structure as far as the slab geometry safely allows. Hot-dip galvanizing matters here specifically because Cibolo watershed clays are moderately to highly corrosive, bare steel and pressed-concrete piers can degrade or stop short inside the moving soil, while galvanized steel holds up in that reactive environment. Most Selma homes stay occupied throughout the work.

Drainage is the other half of a lasting fix. Getting roughly 6 inches of fall over the first 10 feet away from the foundation keeps surface water from soaking the clay along the perimeter. If your lot fights you on that, our drainage and erosion control crews handle the grading and water management that protect the repair long after the piers are set.

Early signs worth a survey in Selma

Catching settlement early keeps both the scope and the cost manageable. Watch for these on your home:

• Stair-step cracks running through the mortar joints of exterior brick
• Interior doors that stick, drag, or won't latch after a dry stretch
• Diagonal drywall cracks fanning up from the corners of door and window frames
• Floors that feel out of level or dip toward one wall or corner
• Gaps opening between the countertop and the wall, or trim separating from the ceiling
• New cracks that widen through a Central Texas summer, then partly close after heavy rain
