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

Types of Rubber Waterstop

1. Common Rubber Waterstop
2. Swellable Rubber Waterstops/Hydrophilic Rubber Waterstop belt
3. Rubber Waterstop with Steel Side
Main types
Rubber waterstop - dumbbell type
Dumbbell type water stops, with flat web section, are ideal for construction and partial contraction joints
with little or no movements.

Rubber waterstop - center bulb type
Center bulb type waterstop, 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.
Applications of Rubber Waterstop
  Ideal for high movements joints.
  Water containments.
  Water excluding.
  Tunnels and civil engineering structures.
  Water and waste treatments.
  Dams, reservoirs, and spillway.
  Chemical areas. 
  Irrigation canals, sea walls and culverts.
 Processing procedures of Rubber Waterstop
raw materials---1st pressing---2nd Pressing & cutting---inner hose shaping with the model---inner hose
frozening(-19°C)---weaving/Twining for several times(as request)---wrapping---vulcanization for 40-50
mins---unwrapping---model extrusion---testing---packaging---finished products

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 waterstops 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
