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.

Types of rubber water stop
1. Common Rubber Waterstop
2. Swellable Rubber Waterstops/Hydrophilic Rubber Waterstop belt
3. Rubber Waterstop with Steel Side
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.

Installation of rubber water stop
Most popular way of the placement of the water stop seal is tied to the steel
frame works or small eyelet by means of small wires, certain metal clamps
made to grip the water stop seal to keep it in proper position. Our water stops
are profiles based on specially formulated plasticized PVC compound, which
are designed to meet specific requirement of building industry. It is essential
that a device is used against potential risk of discomfiture that tends to be
caused in concrete structure following climatic, geo-disturbances and frictional
impasse which result in expansion or contraction in concrete structure. And the
expansion or contraction results in leakage/seepage of water exposing the
structure to bring the risk of cracks or dismemberment
