If a foundation has settled, its is often both the perimeter footing and the interior slab.

Other concrete slabs will include walkways, steps, garage floors, and patios. All can be stabilized and often lifted back to original elevation with polyurethane foam injection.

Small holes are drilled based on the area[s] of settlement, and polyurethane foam is injected underneath the slab to fill voids, and hydraulically lift the concrete slab back to its original level state.

As with all polyurethane foam applications, the cause of settlement must be eliminated, or the possibility of settlement may reoccur.
