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.

rubber water-stop is of high quality natural rubber and various synthetic rubber as the main raw material,adding all kinds of promoter and filling agent, mixing, sulfide, classics 
plasticate, moulding and made a water-stop product, it is using high elasticity 
of rubber, produce elastic deformation under various pressure load, thus have 
strong sealing, can effectively prevent the leakage of building structure, water seepage and shock absorption effect. In many countries in the design of large-scale 
engineering construction, civil engineering, water and soil structure has a certain scale,and there is waterproof and shockproof requirements, so use and install rubber water-stop is effectively solve various problems encountered in the above project.

More varieties of the specification, the shape can be divided into: mountain type, bridge, P type, U type, Z, B, T, H, E, Q, etc. If the usage and classification for   the back and buried the rubber water stop, because the rubber has good elasticity,
abrasion resistance, aging resistance and tear resistance, so the rubber water-stop 
characteristics to adapt to the deformation ability strong, waterproof properties is good, as stipulatedin the domestic rubber water-stop temperature range for 
**5 ºC - + *0 ºC,when the temperature exceeds *0 ºC, or the strong oxidation 
or corroded by oil and other organic solvents, shall not use rubber water-stop.
