Sinking Foundation Repair.
A sinking foundation is settlement you can see and feel. The longer it goes, the more it costs — so we measure it free and stabilize it fast on steel piers.

Signs your foundation is sinking
A visibly low corner, a floor that slopes to one side, doors racked out of square, or a widening exterior crack all point to a sinking foundation. These don’t reverse without intervention.
Stopping the sink
Steel piers driven to refusal beneath the sinking area transfer the load to stable ground and let us lift it back toward level.
Signs you may need sinking foundation repair
- 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
The GroundLock process
Free elevation survey
Map the slab to ±⅛ in and locate every drop.
Drive steel piers
Galvanized piers driven through the clay to load-bearing strata, to refusal.
Lift & lock
Raise toward level; transfer the load onto the piers.
Verify & warranty
Re-survey, document the lift, and warranty it for life.
Protecting the repair
Because water and soil movement cause most foundation failures, lasting results often pair the structural fix with drainage correction, erosion control, or regrading — recommended only where it protects your foundation.
