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 water stops 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.

Features of rubber water stop

  High elasticity.
  High elongation.
  Excellent high movement accommodation.
  Capable to withstand high hydrostatic head.
  Adjust for subsidence and seismic movements.
  Hot vulcanized site joints.

Shapes of rubber water stop

1.Rubber water stop - dumbbell type
Dumbbell type water stops, with flat web section, are ideal for construction and
partial contraction joints with little or no movements.
2.Rubber water stop - center bulb type
Center bulb type water stop, as its name implies, features its center bulb which
makes it ideal for contraction and expansion joints including high lateral,
transverse and shear movements. Meanwhile, it is perfect for withstanding the
subsidence of the joints.

As your request, other types including ribbed type, splitting type, base type or
capping type can be made to your order.
