INTRODUCTION OF WATERSTOP MATERIAL

Huierda waterstop material/ (hole sealing) is a highly reactive, two-component injection resin intended primarily for tunnel and coal pillar sealing against water ingress. It is consists of two-component A+B. mixed at a volumetric ratio of 1:1, which forms an impermeable high strength flexible sealing foam when in contact with water. With low viscosity, Huierda waterstop material can penetrate into the imperceptible fracture, expand and solidify to realize the reinforcement of fractured ground and the plugging of fracture.
