Pipe Joint Sealing Using NCFI's Geotechnical Polyurethanes
Polyurethane injection is a fast and effective way to repair a variety of issues that cause sanitary and stormwater pipes to leak. In one application, the polyurethane simultaneously fills voids, densifies soils, and seals leaking joints and cracks. The polyurethane can be injected from within the pipe or from the surface depending on accessibility and pipe diameter.
When polyurethane is injected in a vertical and horizontal injection pattern, a dense layer of polyurethane compacts and bonds the soil to prevent water seepage and soil loss. Additionally, polyurethane aggressively seeks out and fills voids and seals cavities, cracks, and crevices.
