Rubber Water Stop, Bentonite Waterstop Strip

Hydrophilic Butyl Rubber Waterstopsis a type of hydrophilic water sealing product to prevent any passage of water through non-moving construction joints. Composed of quality butyl rubber and mastic or expansible clay, when exposed to water, the waterstop swells and forms a permanent compression seal in non-moving concrete construction joints.Product show:
Features:
1.High tensile strength, high tear resistance.
2.High break elongation rate, Less compression set.
3.Low fragility Temp, anti-aging ,anti-corrosion.
4.Easy installation, supply with various joint type .
5.Customized to design and construction.
