Detailed introduction
The swellable waterstop is a new rubber product that based on the raw rubber materials, with a polymer material,throughing chemical modification. It has the characteristics of rubber and swellable to proof water.
It be divided into bentonite waterstop and production waterstop.
This is the production rubber waterstop.
The swellable waterstop have the excellent flexibility,expansion ability,plasticity when water intrude,it is widely used in tnnels, subway, sewage plant, the municipal pipe network,Culvert, dam, bridge construction, water conservance, hydropower projects, building underground,Structure construction joints, expansion joints and waterproofing of concrete work required.
