Slabjacking is another method of concrete leveling for raising or supporting structural and non-structural slabs. This system is generally utilized when the normal shrinking and swelling of the soils below the slab is unacceptable because of the cosmetic or structural damage it would cause with the seasonal movement.
Helical piers are installed to a load-bearing soil under the slab to permanently support the slab or structures on top of the slab. The pier is generally installed through a 10” or 12” cored hole through the slab. After the slab is lifted back into place, concrete is poured back into the cored hole, covering the bracket and pier below the slab. This is a great solution for slab homes and slab commercial buildings where the exterior foundations are fine, but the interior slab has settled.
