WHAT IS THE SLAB LIFTING METHOD?
Slab lifting, also known as concrete lifting or slabjacking, is a method used to raise and level concrete slabs that have sunk or settled. There are two primary techniques for slab lifting:
Polyurethane Foam Injection: In this method, a specialized polyurethane foam is injected through small holes drilled into the sunken or settled concrete slab. The foam expands beneath the slab, filling voids and raising it to the desired level. This process is precise, quick, and minimally invasive. Polyurethane foam is often preferred for its lightweight properties, rapid curing, and durability.
Cement Grout Injection: Cement-based grout is another method for slab lifting. Cement grout is injected beneath the concrete slab through drilled holes. As it cures, it provides support and raises the slab. However, cement grout is heavier and can be slower to cure compared to polyurethane foam. It is a more traditional approach. Polyurethane Foam Injection methods aim to restore the concrete slab to its original level, ensuring that it is stable and safe for use.
