Hydrotite CJ (for Construction Joints)

Hydrotite CJ has been developed as an effective, simple and economical sealing material for site formed construction joints based on the proven effectiveness of Hydrotite.

Hydrotite CJ-0725 is the most popular format and is commonly used to provide a high-performance waterstop in large concrete structures. Other Hydrotite CJ profiles are available for construction joints that have larger coverage requirements.

Hydrotite CJ waterstops boast unique triple-action water-sealing performance. Industry test results demonstrate that, after contact with water, the contact surface pressure exerted by Hydrotite CJ increases gradually over a 10 day period.

 Hydrotite CJ Waterstop – Key Unique Properties

  • The natural elasticity of the rubber creates an immediate compressed seal between adjacent surfaces during the construction process
  • Hydrophilic reaction after contact with water creates a secondary expansion – providing a compression seal that compensates for any shrinkage or joint movement, hereby maintaining a water-tight seal
  • High performance Hydrotite products have residual expansion capabilities, to maintain the integrity of the compression seal integrity against any potential water infiltration caused by future structural movement.

Features of Hydrotite CJ

  • Expands up to 5 times original size after contact with water
  • Hydrophilic polymers provide controlled expansion of the chloroprene rubber following contact with water
  • No risk of premature expansion, thanks to a Delay-Action Coating
  • Delay-Action Coating allows the concrete to gain strength prior to expansion of Hydrotite strips, preventing cracking in green concrete
  • Co-extruded design regulates expansion across the joint (instead of along path of least resistance)
  • Co-extruded design ensures that higher contact surface pressure is achieved for sustained high water-sealing performance
  • Good resistance to bacteria and common chemicals

Application of Hydrotite CJ

  • Quick, easy and economical to install
  • Does not require complicated split forming
  • Flexible waterstop profiles can be applied in a gradual curve to maintain a continuous waterstop between a floor joint and a wall joint
