Common Repair Methods and Their Benefits
Each repair technique addresses specific foundation issues:
- Piering (Concrete or Steel Piers) – Drives support columns into bedrock or stable soil, lifting the slab. Ideal for severe settlement.
- Slab Jacking – Uses hydraulic jacks to lift and level a concrete slab. Works best for localized sinking.
- Underpinning – Replaces or extends existing foundation walls with new footings. Suitable for extensive wall damage.
- Drainage Improvements – Installing French drains or sump pumps reduces moisture that can weaken foundations.

Foundation repair costs vary widely. In Ann Arbor, typical ranges are:
| Repair Type | Estimated Cost | Factors Influencing Price |
