CP Rubber Waterstop


A WATER STOP is usually a section of flexible waterproof material placed at any jointin concrete to prevent the passage of water. Waterstop plays a critical role in the integrity of concrete structures. It is used as a fluid-tight diaphragm, embedded in concrete, across and along the joint, for primary  and secondary containment structures.


The superior chemical resistance of  RUBBER WATERSTOP Rubber  Waterstop is available in a 6, 8, 9  and 10 inch  width for dumbell flat type and 6, 8, 9, and 10 inch  width for dumbell center bulb type. It provides for greater mechanical bonding with the concrete and a barrier against migration of liquid flow around the waterstop. The dumbell center bulb type also allows for joint movement. The width of the waterstop must be less than the thickness of the concrete.


  • Surface preparation: Surfaces should be clean and dry. Remove all dirt, rocks or other debris.
  • Install Rubber Waterstop in all concrete joints. Waterstop should be centered in and run the extent of the joint.
  • Join adjacent pieces of Waterstop in accordance with the glue.
