Groundtek void filling solutions can be used to fill any size of void. Our systems are ideal for filling pipelines, basements, tunnels, caves, mine shafts and conduits. Groundtek specialise in the application of a range of materials to fill voids, depending on the size and location. Our solutions have proved to be a super-fast alternative to conventional void filling. All of our materials are recyclable, so if at a later date the void needs to be accessed, the geopolymer can be removed.

Where required, we also provide a specialist load bearing void fill solution that can be applied directly and through a small hole, offering a non-disruptive solution for the customer needs. The Groundtek void filling process involves filling a cavity, either with a specific Groundtek geopolymer or with a combination of deactivated clay balls and Groundtek geopolymer. The filling is achieved by using lightweight materials that do not overload the underlying soil. In case of a damaged structure above the void, the ground between the void and the structure can be treated by applying Groundtek ground improvement solutions.
