 Waterstop Bar:
PN Water-swellable Rubber Waterstop Bar
 
Description:
PN water-swellable water-stop rubber bar is a new waterproof sealing material. It is applicable for construction joint, expension joint and crack of swimming pool, wastewater treatment, subway, tunnel and other concrete works.
Features:
It is preseted on the interface of construction joint and consequently-cast joint,there is swelled with water and could completely block joint water after secondary casting of concrete (enclosed by concrete ).
The expesion rate is slow and water pressure resistance is strong. It is appliable for construction in rain season and construction site with much water.
The construction method is simple.It may have effect of water proofing and seepage resistance when properly utilized.
The main material is inorganic minerial and it features aging resistance,corrosion resistance and no pulution.
