Cost Effective Method of Shallow Sinkhole Repair

Shenandoah is a licensed affiliate of Uretek. Uretek’s (UDI) 2 stage deep injection polymer process has led the industry since the 1980’s. Our cost effective, eco-friendly, deep polymer injection process gives long-term stability to areas effected by shallow sinkholes. This combination of chemical, compaction, and permeation grouting will stabilize the soil at the throat of the sinkhole. The polymers expand and compress loose soils, fill subsurface voids, fissures, cap any underground soil pipes, and tightly bond with surrounding soils. The industrial polymers reach 90% of their strength in 15 minutes, and 100% of strength in 24 hours, creating an impenetrable watertight barrier, restoring the integrity of subsoil. Our innovative polyurethane chemical grouting process is the safest, most cost effective, and most precise method of remediating and repairing shallow sinkhole voids within 15 feet of the surface.
