Common foundation problems in Castle Hills
Across Castle Hills, the calls we get most involve settlement along the perimeter beam, dropping corners, and cracks that reopen after patching. They almost always trace back to the ground beneath the slab.
- Doors and windows that stick, drag, or won’t latch
- Stair-step cracks in exterior brick or block
- Sloping, bouncy, or visibly uneven floors
- Drywall cracks fanning from door and window corners
- Gaps opening between walls, trim, and the ceiling
- Cracks in the slab or at the garage floor
Why slab foundations move in Castle Hills
Expansive clay that has already moved many of its original slabs. When that ground cycles between wet and dry, a slab cast on it moves too — and surface patches move right along with it.
Why GroundLock uses steel piers
Underpinning extends support downward to soil that can carry the load. GroundLock underpins with driven steel piers, logging drive force at each pier and re-surveying the lift — verifiable, permanent support.
