Pressure Grouting – A Shallow Method of Repair

Pressure grouting 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.

In the pressure grouting process, instead of replacing the concrete, cement slurry is pumped under the concrete. This process “lifts” the sunken and uneven surface back into its proper position. Performed properly, pressure grouting can not only bring the concrete up to grade, it can also eliminate costly and irritating water problems by filling hidden cavities under the concrete and diverting water away from the foundation.
