CJ Form-Tie Waterstops

CJ Form-Tie Waterstops are produced from a unique hydrophilic rubber sealing compound which expands in a controlled fashion when exposed to moisture.

Description

CJ Form-Tie Waterstops are produced from a unique hydrophilic rubber sealing compound which expands in a controlled fashion when exposed to moisture. This forms a compression seal inside or around the form-tie system in the concrete structure, giving a permanent flexible watertight seal.

Available in a number of different sizes and profiles to suit the form-tie system. Once installed, CJ Form-Tie Waterstops forms a continuous barrier, making it ideal for preventing water penetration or egress.

Advantages of CJ Form-Tie Waterstops:

  • Excellent sealing capabilities and available in many different sizes, shapes and profiles to suit the formwork form-tie system to be used. Custom profiles available upon request.
  • Provides a permanent, flexible gasket and compression seal inside the concrete.
  • High quality, non-biodegradable compounded hydrophilic rubber that provides long-term durability and integrity.
  • Ability to expand up to 200% in contact with potable water and over 150% expansion in salt water.
  • Has been tested to withstand over 50 metres of hydrostatic water head pressure. (Test report available upon request)
  • For use in many different types of applications but especially suited for water retaining structures where direct water pressure is applied against the concrete and the form-tie system.
  • Non-toxic and can be used in potable water structures.
  • Unaffected by repeated wet and dry cycles.
  • Fast and simple to install.
  • Expansion is controlled via the built-in expansion delay system. The product does not pre-expand from the water in the freshly laid concrete of the wall, allowing the concrete to gain strength first.
