For which problem is slab stabilization the most appropriate repair method?

Slab stabilization is particularly effective for addressing voids in PCC (Portland Cement Concrete) pavement caused by pumping. When water is pumped out from beneath a slab, it can result in loss of support and thus create voids beneath the pavement. This can lead to the slab becoming unstable and uneven. Slab stabilization involves injecting materials such as polyurethane or cementitious grouts to fill these voids, restoring support and preventing further pavement distress.

This method specifically targets the underlying issues caused by the voids, effectively stabilizing the slab and prolonging its service life. The injection of stabilizing materials addresses both the immediate concerns of instability and potential future damage, making it a highly suitable solution in these scenarios.
