We can stabilize and lift any size or type of concrete slab. We use a specialized geotechnical foam which is injected under a sunken concrete slab. The foam creeps to fill the entire void and as expansion occurs, the concrete slab is lifted back into its original position. The foam is hydrophobic meaning it will displace any water in the void, set up and stop water from entering the space ever again. Geotechnical spray foam hardens completely within minutes of application allowing use of the concrete slab immediately after installation. Concert lifting spray foam will fill the void, stabilize the concrete slab and ensures a long-term solution is achieved.
