Hydrotite CJ Waterstop

Hydrotite CJ is a high performance waterstop for concrete construction joints that require long-lasting, high-performance protection against water ingress, for hydrostatic pressures of up to 0.5 MPa (50 metre head of water). Hydrotite is a highly effective and reliable waterstop system consisting of a composite hydrophilic and non-hydrophilic rubber strip. It expands at a controlled rate on contact with moisture to provide a 100% watertight seal.
Once in place, Hydrotite provides triple protection against water ingress by:
  • Creating an immediate compressed seal between adjacent concrete joint surfaces due to the natural elasticity of the rubber
  • Expanding through hydrophilic reaction to create a secondary watertight compression seal that compensates for any shrinkage or joint movement
  • Maintaining hydrophilic properties to protect against further water infiltration in the event of future structural movement

Why use Pozament Hydrotite CJ?

Hydrotite CJ is used as a waterstop in concrete construction joints requiring long lasting, high-performance protection against hydrostatic pressures up to 0.5 MPa (50 metre head of water).
Hydrotite CJ waterstop is flexible and easily worked around corners, angled joints and curves to a minimum 60mm radius. This makes it easy to install even on complex shapes, without the need for specialist tools or fixings.
Hydrotite CJ is a composite strip of blue hydrophilic (water absorbing) and black non-hydrophilic rubber. On contact with water, the hydrophilic rubber expands to seal gaps and prevent further water ingress in precast and cast-in-situ joints. The dark blue hydrophilic rubber turns light blue as it absorbs water, giving a clear visual indicator of any premature expansion.
