What Is a RAM Jack Foundation Repair?
A RAM (rising air‑mold) jack is a hydraulic device used to lift a foundation that has settled or shifted. The system applies controlled pressure from underneath the structure, raising it to its original level and allowing the contractor to seal cracks, re‑grout, or replace damaged concrete. The process is often chosen for large‑scale or high‑profile foundations where a traditional jack may not provide enough lift.

Accessibility Issues
If the foundation is surrounded by landscaping, driveways, or other structures, additional demolition or protective work may be needed.
Concurrent Repairs
Many projects combine a RAM jack lift with crack repair, re‑grouting, or waterproofing. Each added step adds to the final bill.

Ask about warranties on the lift, jacks, and any concrete work.4. Confirm that the estimate includes a contingency for unforeseen issues such as hidden damage.
