Compared to traditional underpinning and piling techniques, geopolymer resin injection, a more modern method of subsidence correction, offers a cleaner and quicker treatment for buildings affected by subsidence.
Geopolymer resin injection begins by first drilling holes around the perimeter of the building at depths below its foundations and/or through concrete slabs. This is accomplished using handheld equipment ensuring accessibility both inside and outside the structure. Injection tubes are then inserted into the holes, through which geopolymer resin is injected. As the resin expands, it fills voids, compacts the soil and reinforces the ground. There’s no need for trench excavation, concrete mixing, heavy piling machinery, or the management of spoil collection and disposal, which are typically associated with traditional methods.
The minimal equipment required for geopolymer injection enables ground reinforcement through resin injection from both the exterior and interior of a building. This results in minimal disruption for the occupants within the building.
However, don’t just take our word for it, let’s see what some construction professionals thought when they chose Mainmark’s resin injection technology over more traditional methods.
