Void Filling and Backfilling Services for Ground Control and Abandoned Workings
GMS offers void filling and backfilling services to stabilize abandoned mine workings, control ground movement, and improve structural safety underground. Using cementitious grout, fly ash blends, or other engineered fill materials, our crews fill mined-out areas, subsidence zones, or unused entries to prevent collapse and improve overall ground integrity. Whether part of a remediation plan or new development, backfilling helps extend mine life and improve safety in surrounding areas.
