PROFESSIONAL VOID FILLING THORNBURY
Underground voids in Thornbury can result from historical mining, dissolved limestone, or washout from failed drainage. Our void filling service in Thornbury uses geopolymer resin to permanently fill cavities and prevent sudden ground collapse across South Gloucestershire.
HOW VOID FILLING WORKS IN THORNBURY
Geopolymer resin or cementitious grout is injected through small-diameter holes drilled into the ground. The material flows into voids, expanding to fill cavities and consolidating surrounding loose soils. Real-time monitoring ensures complete void filling without over-pressurising the ground.
Our Thornbury team has extensive experience with the local geology and property types, ensuring the right approach for every project.
