CRYST INJECT FOAM

CRYST INJECT FOAM® is a flexible, water-reactive polyurethane injection foam system designed to be fast foaming resin, which is used as a water stopper permanently against strong water flow. CRYST INJECT FOAM® is typically used to repair cracks or failed joints in concrete structures, and tunneling to seal fractures in rock formations. Component B serves as a catalyst and adjusts the reaction time. A lower dosage leads to a prolongation of the reaction time. In contact with minimal amounts of water, CRYST INJECT FOAM® reacts very fast to foam with closed cellular pores and shape-retaining hard flexible PU foam. After curing the material does not shrink due to wet/dry cycles. CRYST INJECT FOAM ® has excellent penetrates deep in fine cracks to seal water and moist cracks permanently, making a watertight system.
