Foundation Inspection Selma, TX.

Selma homes live on top of Houston Black clay that never really holds still. Sitting inside the Cibolo Creek watershed, the ground here swells through a wet spring, then shrinks into hard, cracked blocks by late August, and the slab riding on it deflects a little more with every cycle. By the time a door starts dragging or a hairline crack reopens over the sofa, the soil has already been at work for a while.

A GroundLock inspection is the step that separates a cosmetic scare from real settlement. Instead of guessing at what a crack means, an engineer measures the actual shape of the floor, ties every symptom back to that map, and hands you a written report you can act on, or file away with peace of mind. The elevation survey is free, and nothing gets recommended until the numbers say it should.

What the inspection actually looks at

A real inspection starts outside and works inward. Here's what an engineer documents on a typical Selma property:

• Site drainage, whether grade falls at least six inches over the first ten feet from the beam, plus ponding zones and downspout discharge points.
• Tree proximity, mature live oaks and cedar elms within ten to fifteen feet, whose roots pull moisture out of the clay and drag one section of foundation down.
• The elevation map, floor readings on a grid, revealing center doming, corner sag, or a single edge deflecting where water concentrates.
• Door and window behavior, measured gaps at frames and openings that rack out of square, the clearest sign of differential vertical movement.
• Crack orientation, diagonal cracks running from corners (vertical movement) versus horizontal cracks (lateral earth pressure), and anything wider than a quarter inch.
• Repair history, cracks that have reopened after previous work, which raise the concern level considerably.

Why the elevation map matters more than the cracks

Cracks are a lagging indicator. They migrate under thermal expansion, they widen and close with humidity, and they don't reliably mark the lowest point of a floor. The elevation survey does. When we lay the readings out, the shape of the deflection tells the story: a slab domed at the center usually points to interior desiccation after a dry Central Texas summer, while sag along the perimeter beam signals soil shrinkage or loss of fines below the grade beam.

That distinction changes the whole plan. Center lift is often managed with soil-moisture measures, deep-watering programs and root barriers, while perimeter settlement needs mechanical support. Getting it backwards leads to repairs that either fail or fix the wrong location, which is exactly what measuring first prevents.

It also matters that the active zone in Selma's clay commonly runs 10 to 15 feet deep. If a repair is warranted, galvanized steel piers have to be driven past that moving layer into competent bearing strata, anything shallower just rides the soil. And if your grade slopes toward the house, we flag it: correcting drainage is usually a prerequisite, because a newly leveled slab will re-settle unevenly if the water problem stays.
