PN Expandable Swelling Rubber Water Stop Strip
Introduction:
PN expandable swelling rubber water stop strip is a new waterproof sealing material.It is applicable for construction joint,expansion joint and crack of swimming pool,wastewater treatment,subway,tunnel and other concrete works.
Features:
--It is preset 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 elongation is slow and water pressure resistance is strong.It is applicable 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 mineral,and i features aging resistance,anti-corrosion and without pollution.
