Rubber Waterstops is designed to be cast in as an integral joint sealing system for in-situ
concrete, water retaining or excluding structure where maximum performance is required as a result of high movement or hydrostatic head. These joints typically occur in reservoirs, dams and spillways, tunnels and other major civil engineering structures.
Â
Size:
The appropriate waterstop width depends upon the concrete thickness, the aggregate size and the position on the reinforcement.
Popular size
200mm width, 6mm thick
250mm width, 6mm thick
300mm width, 6mm thick
350mm width, 8-10mm thick
400mm width, 12mm thick
450mm width, 20mm thick
500mm width, 20mm thick
Advantages of Rubber Water Stop:
•  High degree of elasticity to accommodate pronounced cyclic movement
•  High elongation to cater for subsidence and seismic movement
•  Withstands high water pressure
•  Hot vulcanised site joints
Prefabricated networks can be supplied to reduce site jointing. The range consists of straight lengths and intersections in centre bulb or plain web dumbbell profiles for expansion and construction joints.
Profiles:
Rubber watestop-centre Blub type
Suitable for subsidence, contraction and expansion joints, including high movement
joints.Meanwhile, it is perfect for withstanding the subsidence of the joints.
Rubber water stop- dumbell type
Suitable for construction, kicker and partial contraction joints where no shear movement is possible.
As your request, other types including ribbed type, splitting type, base type or
capping type can be made to your requirement.

Applications of rubber waterstop:
Water retaining structures
Rubber waterstop are recommended for sealing high movement  expansion  joints.  They  are particularly recommended for sealing joints subject to high water pressures in such structures as irrigation canals, culverts,dams, reservoirs, sea walls and sewage works.
Â
Which Water Stop functions better; PVC or Rubber Water Bars?
Rubber waterstop is a hydrophobic water sealing products capable to withstand high water pressure and absorb high movements of concrete joints. Generally, SBR, neoprene rubber and natural rubber are the main materials for manufacture of rubber waterstops. One particular material waterstop suits one particular condition. |
PVC waterstop, as the most common watertight type, features high tensile strength, elongation capability and high resistance to acids, ozone, alkalis, diesel oil, chlorinated water and other chemical liquids. Meanwhile, they will not discolor the concrete or support even produce electrolytic action with surrounding reinforcing steels. |
