Description of butyl waterstop:
Butyl rubber waterstop is 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.
Features of butyl waterstop:
1.Preserve its integrity with self-control ability.
2.Easy and fast to install owing to its high self-adhesive properties to dry surface.
3.Form a permanently flexible watertight joints.
4.Anti-aging without shrinkage, hardening and oxidization.
5.Withstand harsh temperatures ranging from -30F to 200F.
6.Non-toxic.
7.No need of special handling.
