Slab Lifting by injecting structural polyurethane foam into voids beneath settling or uneven concrete slabs is a proven method to stabilize without excavation and without adding much weight. Slabs can be lifted to their original position utilizing the SealBoss SlabLifter system and products. This process of slab jacking is alo known as foam jacking, polyurethane concrete raising, poly jacking, poly leveling. Compared to the other methods of mud jacking, using chemical grouting offers many advantages.

Foam jacking is used in industrial and residential markets. Foam jacking is the cleanest concrete lifting and stabilization process. Drilling is clean and fast due to the small hole size. Foam jacking is the quietest and fastest process for stabilizing and raising settled concrete slabs. Lightweight material reduces the overburden on underlying soils, reducing the chances for resettlement. High density polyurethane is waterproof, so treated slabs are thoroughly undersealed.
