Sinking Foundation Repair in Austin, TX.

Looking for sinking foundation repair in Austin? Here’s why local slabs move — and exactly how we fix them.

Common foundation problems in Austin

Across Austin, the calls we get most involve a visibly low corner, a floor that pitches to one side, and doors racked out of square. 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 Austin

Notorious 'Austin clay' east of MoPac; thin soils over limestone to the west. 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

A sinking foundation is settlement you can see and feel. Steel piers driven to refusal beneath the sinking area transfer the load to stable ground and let us lift it back toward level before the damage compounds.

Drainage, grading & moisture control
