Product Description

Description of Rubber Water Stop

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 and other water retaining or excluding applications with high movements or water pressure.

1. The rubber water stop strip will expand when getting in touch with water, so allowing it to come into closer contact with the concrete, creating a better water-stop result.
2. Different thicknesses structure is adopted for the cross section, which is divided into the high-strength area, the waterproof area and the installation area, allowing for uniform and reasonable stress for all portions.
3. At installation area add installing hole, it could facilitate fixed with adjacent reinforced, and not produce shifting. Construction is convenient, positioning installation is firm.

Advantage of water stop

Its basic advantage is in its time of fixing. It works as a sealant and it is fixed on predetermined place while concrete slab is laid. It is easy to install and easy to weld at site and at required angle & shape.
