Water-based grouting solution is a polymer grouting plugging material chemically synthesized from cyanate and polyhydroxy polyether. After encountering water, the material quickly expands, foams, solidifies, and clogs its cracks and pores, forming an elastic gelatinous solid body, which can achieve a good purpose of water stop. It is a new generation of waterproof and leak-blocking materials.

Oil-soluble polyurethane grouting solution (oil-soluble polyurethane plugging agent), which is a light yellow or brown transparent viscous liquid, is a chemical grouting material formed by the reaction of a composite polymerized polyol and a polyisocyanate containing an isocyanate group at the end.It has a large penetration radius and solidification volume ratio. When encountering water, chemical energy reacts to release CO2. The pressure generated by the gas pushes the slurry to diffuse deep into the cracks, forming a tough solid body.Other names: oil-soluble polyurethane grouting solution, oil-soluble polyurethane plugging material, oily polyurethane grouting solution, oily polyurethane grouting solution, oily polyurethane plugging agent, oily polyurethane plugging material, hydrophobic polyurethane grouting solution, hydrophobic polyurethane plugging agent, hydrophobic polyurethane plugging material, hydrophobic polyurethane grouting solution.

Water-based product features

◎ The slurry reacts immediately after encountering water, foams and expands to block water leakage.

◎ The formed elastic gelatinous solid body has good ductile elasticity, impermeability, low temperature resistance, and permanently maintains its original shape in water.

◎ It has low viscosity and good irrigability. Soaking the consolidated body in water is harmless, non-toxic and non-polluting to the human body.

◎ Suitable for single-liquid high-pressure perfusion machine.

Oily product features

◎ One-component, no need to measure and mix.

◎ It has good hydrophobic properties, high chemical stability, high strength and good toughness.

◎ It is resistant to acid, alkali and organic solvents, and has good chemical resistance.

◎ The coating is smooth, wear-resistant, and does not grow mold.

◎ Excellent bonding performance with concrete base layer and other building materials.

◎ The viscosity and curing speed of the grouting glue can be adjusted according to the needs of the project.

Construction process

Clean up the dirt in the leaking area to find the leaking place, drill holes and bury needles every 10-30cm, pour the grouting material into the grouting machine cup according to the amount, connect the needle, start the grouting, and stop when the leaking point or adjacent hole exposes the slurry.

Scope of application

This product is suitable for any water-containing and leaking concrete cracks, tunnels, subways, dams, bridges, basements, toilets, expansion joints, etc. Under high water pressure, an appropriate amount of catalyst can be added to quickly foam, expand and solidify.
