Fibgrout PU 2K is a pre-blended CFC free polyurethane polyol for two component (2K) rigid foams for injection grouting purposes. The system gives out a foam with a fine rigid cell structure and good inter- laminar adhesion. The system uses SIPANE as our in-house developed eco-friendly blowing agent. The system is injected via a high-pressure twin piston pump in conjunction with a in-built line mixer nozzle into the cracks/voids of walls, roofs, tunnels, etc. The system foams up irrespective of any water contact in the cracks or voids, with a fast reaction profile. The fast reactivity helps the grout to expand quickly and seal off the water flow of cracks and voids immediately. The reactivity of the system increases as and when the system comes in contact of any water or moisture.
