Description of rubber water stop
Rubber waterstop, made of quality SBR (styrene butadiene rubber),neoprene rubber or natural rubber, is one of the widest types for concrete structure to prevent liquid leaking in or out. Generally,designed to be cast in the concrete, rubber water stops are ideal for applications where high physical properties of rubber are required. For example,reservoirs, dams and other water retaining or excluding applications with  high movements or water pressure.



Features of rubber water stop
  High elasticity. 
  High elongation.
  Excellent high movement accommodation.
  Capable to withstand high hydrostatic head.
  Adjust for subsidence and seismic movements.
  Hot vulcanized site joints.
