Corkjoint CJ Form-Tie Waterstops | Hydrophilic Rubber Form-Tie Waterstops

CJ FORM-TIE WATERSTOPS 

Description 

Corkjoint 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.

• 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.
