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.

  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
