It is a polymer chemical grouting material with isocyanate groups at the end, which is formed by the reaction of hydrophilic polyether polyol and isocyanate. This material undergoes a chemical reaction when it comes into contact with water to form an elastic gel-like solid body, thereby achieving a good water-stopping purpose. It is a new type of waterproof and leak-proof high-pressure grouting material.

It is a leak-proof product that has the characteristics of rapid leak-proofing without disassembly. After being injected into the concrete, it reacts chemically with water, and through its slow expansion and continuous pressure, the grouting material can penetrate into tiny gaps, expand and solidify in a short time, and achieve the purpose of complete water stopping.

It is a closed secondary amino polyurea resin. It starts to react and solidify when it comes into contact with water or moisture in the air. No gas is released during the reaction, and the coating is dense and free of bubbles. It does not expand during curing and does not shrink after curing. It is environmentally friendly and non-toxic. It has strong wet adhesion and can be cured directly in water. Grouting in place can reinforce and plug leaks at the same time.
