Hydrocryl 2000


HYDROCRYL 2000 is a single component polyurethane resin which is designed for injection into voids and cracks to halt water ingress. It is mixed with the catalyst component, to achieve the desired reaction time. The resin cures quickly to form a semi-rigid closed cell polyurethane foam which will resist water ingress whilst remaining flexible for the lifetime of the structure.


HYDROCRYL 2000 is used for sealing cracks and voids where water penetration is occurring. Applications include the grouting of tunnel segments, sealing of poly compacted concrete and filling of voids in substructures.
