GeoStabilization provides design-build geohazard remediation repairs including geophysical survey and assessments of discovered underground voids and sinkholes. Repair methods may include stabilizing and halting any retrogression and expansion of an existing sinkhole. Repair methods may consist of grouting – cementitious backfill into the sinkhole to stabilize the land and above structure(s).
An expandable foam grout expands into existing cracks and crevices, bonding the detached rock together and solidifies critical areas from potential rockfalls below. This effort preserved a degrading bench from further eroding and maintaining proper catchment.
A variation of karst sinkhole grouting is the grouting of mined coal seams and workings located below existing infrastructure that exhibit the potential to propagate to the surface and cause sinkholes and/or subsidence.
