Oil-soluble polyurethane grouting material is a single-component, high-expansion, hydrophobic material. When the slurry encounters water, it foams and expands, forming a dense, closed-cell rigid foam body, used for water stop and rapid leak plugging of non-active cracks.
Implementation Standard
《Polyurethane Grouting Material》(JC/T2041-2010)
Product Features
Low odor/More environmentally friendly/High density.
Scope of Application
Suitable for seepage prevention and plugging treatment of non-active cracks under long-term water or dry-wet alternating environments.
Construction Points
◆ Check the leaking area, clean up debris, confirm the crack, then drill holes and install the grouting nozzle.
◆ Use a single-component high-pressure grouting machine for construction. Starting from the first grouting nozzle, inject the slurry from low to high pressure. Gradually increase the pressure. When slurry appears in adjacent holes, move to the adjacent hole and continue to inject;
◆ After the first grouting is completed, return to the first grouting nozzle and grout again;
◆ After 72 hours, check the leaking area for any seepage. If there is no water, remove the exposed grouting nozzle and seal and smooth the surface with epoxy mortar or sealant 2.
