Slab Foundation Repair

What slab foundation repair involves

A repair crew first maps the slab's elevation to see how far each area has dropped, then drives piers — pressed concrete or steel — down through the active clay to stable load-bearing strata. Hydraulic jacks raise the settled sections, the piers are shimmed and locked off, and interior cracks, doors, and trim are addressed as the house returns to plane. Most crews finish in two to four days for a typical perimeter job.

1. 01Elevation surveyA zip-level or laser maps how far each part of the slab has dropped relative to the high point.
2. 02Pier placementPressed-concrete or steel piers are driven through the clay to load-bearing strata beneath the active zone.
3. 03Lift & stabilizeHydraulic jacks raise the settled areas in stages; piers are shimmed and locked off at the engineered height.
4. 04Backfill & finishAccess holes are filled, perimeter grading is corrected, and a transferable warranty is documented.
