Concrete Lifting and Slab Lifting
Concrete lifting, or slab lifting, raises settled residential flatwork back toward its original elevation instead of removing the concrete. It is used on driveways, sidewalks, patios, pool decks, and slabs where the concrete is still intact but has dropped, tilted, or lost support beneath it.
A lifting material — polyurethane foam through small injection holes or a cementitious mudjacking slurry through larger holes — is introduced at lifting points beneath the slab to fill voids and raise the concrete in a controlled way. The choice depends on slab condition, void size, and the transitions between adjacent panels.
The result is a more even, safer surface with reduced trip hazards and improved transitions between slabs, while preserving the existing concrete and avoiding the cost and disruption of a full tear-out.
