CJ FORM-TIE WATERSTOP

• 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.

Water retaining structures:

• Water Tanks
• Reservoirs
• Dams
• Water Treatment Plants
• Sewage Treatment Plants
• Swimming Pools
• Bund WallsWater excluding structures:

Water excluding structures :

• Basements
• Underground car parks
• Tunnels
• Stations & Subways
• Retaining Walls
• Pits & Manholes

Note : The product’s design and performance, its intended use, installation and final confirmation and approval for use, must be provided by the project’s Design Engineer and Project Manager.

• Due to the expansive forces of the hydrophilic rubber compound, CJ Form-Tie Rings need to be installed with a minimum concrete cover of 75mm from any outside edge.
• Increase concrete cover when using lightweight or low strength concrete.
• Expansion rate can vary in potable water and salt water environments.

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 place.

• Exposure & Water Immersion Expansion in Potable Water
• Exposure & Hydrostatic Head Pressure (cyclic wet & dry) in Potable Water
• Water Immersion Expansion in Salt Water (In-house)

The Form-Tie Waterstop shall be CJ Form-Tie Waterstop (State profile number required) as supplied by CORKJOINT. The Form-Tie Waterstop shall be produced from Chloroprene Rubber and compounded with special hydrophilic polymers to be able to achieve a minimum expansion capability of 200% in potable water and a minimum of 150% expansion in salt water. The Form-Tie Waterstop must be able to withstand a hydrostatic water head pressure of not less than 5 Bar and an independent laboratory test report must be provided to prove the product material type, the water immersion expansion percentage and the hydrostatic water head pressure capabilities.

In confined spaces or in still air conditions, the use of a ventilation fan or suitable respirator should be used, and the advice and approval of the Site Safety Supervisor is essential. For further information or advice on health and safety precautions, safe handling, storage and correct disposal of products, please refer to the most recent product Safety Data Sheet (SDS)  which is available upon request.
