It is the process of raising or stabilizing faulty concrete pavement, and is performed on cracked and sunken concrete slabs such as driveways, steps and sidewalks, concrete pavement floors and other slab on grade surfaces. It is referred to as slabjacking when lifting or leveling is involved, or simply pressure grouting where void filling is the sole objective.
In the slabjacking process, instead of replacing the concrete, a cement slurry is pumped under the concrete. This process “lifts” the sunken and uneven surface back into it’s proper position.
Slabjacking can not only bring the concrete up to a grade, it can also eliminate costly and irritating water problems by filling hidden cavities under the concrete and diverting water away from the foundation. Slabjacking is the cheapest alternative to replacement!
