Koster IN 7

Koster IN 7

Koster IN 7 is a single component viscoplastic PU-injection foam for waterproofing of cracks in concrete and masonry. It stops leakages even under pressurized water. IN 7 is applied in a single step without necessity of subsequent injection with a solid body resin.

Koster IN 7 is a single component polyurethane prepolymer used with 10% catalyst. The product reacts when it comes into contact with water and forms a compact, viscoplastic waterproof polyurethane foam. IN 7 remains viscoplastic after reacting and is thus able to follow crack movements and to seal permanently without the necessity of subsequent injections with an elastic polyurethane massive resin.
