"Slab Stabilization" 16 August 2007. http://www.pavementinteractive.org <http://www.pavementinteractive.org/article/slab-stabilization/> 24 May 2015
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). Voids are typically filled by pumping grout through holes drilled through the slab.
Preventive and corrective maintenance. Restores proper base/subgrade slab support to prevent more serious distresses such as faulting, corner breaks and cracking.
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.
