Slab stabilization seeks to fill voids beneath the slab caused by pumping, consolidation or other means. If left untreated, these voids, which are often quite small (on the order of 3 mm (0.125 inches) deep), may cause other problems such as faulting, corner breaks or cracking (ACPA, 1995[1]). Voids are typically filled by pumping grout through holes drilled through the slab.

Purpose

Preventive and corrective maintenance. Restores proper base/subgrade slab support to prevent more serious distresses such as faulting, corner breaks and cracking.

Materials

Pozzolan-cement grout.

Other Information

Slab stabilization only fills the voids under a slab, it should not be confused with slab jacking, which is used to raise the elevation of a depressed slab.
