WEBAC® PURstop 1C
WEBAC PURstop 1C is a single-component, polyurethane-based injection resin with a catalyst. Upon contact with water, it reacts rapidly and expands vigorously, forming an elastic, adaptable foam that reliably stops water ingress. The reaction time can be adjusted using the WEBAC PURstop ACC 1C catalyst. It is suitable for sealing Foundation Pits, for solidification of loose soils, and for filling voids.
