The term Re-leveling: refers to the lifting of a structure that has experienced differential settlement. There are three common types of Re-leveling
- Underpinning and Re-leveling: The existing foundation is underpinned and then Re-leveled by raising the foundation using hydraullic jacks.
- Cosmetic Re-leveling: The existing foundation remains in place while the structure's framing unfastened from the foundation and then lifted. A cap is installed on the foundation after Re-leveling and the framing is Re-attached.
- Pressure Grouting: This method is usually applicable to concrete slab floors. Holes are drilled through the concrete slab in a grid pattern and pressurized is pumped beneath the slab, lifting the structure.
