Description of rubber waterstop:
Rubber waterstop, made of quality SBR (styrene butadiene rubber), neoprene rubber or natural rubber, is one of the widest types for concrete structure to prevent liquid leaking in or out. Generally, designed to be cast in the concrete, rubber waterstops are ideal for applications where high physical properties of rubber are required. For example, reservoirs, dams andother water retaining or excluding applications with high movements or water pressure.
