Product description
high quality steel edge rubber waterstop
The sections divided into high-strength area, water-proof area and the installation area can take unequal thickness structures according to the unique function of every area. So each part of the sections can get uniform and reasonable force. The outer wall surface of the stretch shrinkage is plane, the construction of the formwork folder system is not easy dislocation; Steel plate connected to additional mounting holes and reinforced rigid fixation is not easy displacement. Good adhesion betweengalvanized steel and concrete makes the waterproof performance better.
Application of steel -edged rubber water stop
It can be widely applied to various types of concrete structures, such as: Dams, reservoirs, subway, culverts, tunnels and other underground works.
Types of steel -edged rubber water stop
NR means natural rubber: The width of NR rubber water stop is 350mm, and the material of rubber water stop is natural rubber. Rubber water stop is applied to the freshwater seepage control project and it is applicable between -40~60ºC.
CR means chloroprene rubber: The width of CR rubber water stop is 350mm, and the material is neoprene and it is applied to chemical and other sewage seepage project and it is applicable between -35 ~ 60ºC.
NBR means Nitrile Butadiene Rubber : The width of NBR rubber water stop is 350mm, and the material is nitrile rubber and it is applied to sewage seepage control project which contains petroleum oil and so on and it is applicable between -35 ~ 60ºC.
