CJ Form-Tie Waterstops are produced from a unique hydrophilic rubber sealing compound that 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 permanently flexible watertight seal.
Available in a number of different sizes and profiles to suit the form-tie system. Once installed, CJ Form-Tie Waterstops form a continuous barrier, making it ideal for preventing water penetration or egress.

1. FORM-TIE CONDUIT SPACER HOLE
2. FORM-TIE RODS
a. Thoroughly clean the outside surface of the form-tie rod, free of any dust, debris & foreign matter.
b. Place the CJ Form-Tie Ring over the outside face of the form-tie rod and slide it along to approximately the middle section.
c. A minimum concrete cover of 75mm from any outside edge of the concrete to the CJ Form-Tie Ring should be followed.
d. Check and make sure that the CJ Form-Tie Ring has a tight and secure fit around the sleeve or rod. If it is loose, then a smaller diameter ring should be used.
e. The CJ Form-Tie Ring is now ready for the concrete to be placed.
The above profile types are standard and custom profiles are available upon request to suit the form-tie system to be used. Selecting the profile type is dependent upon the type of form-tie system being used and if needed, please consult CJSA for further information.
