Krytonite Swelling Waterstop 51mm x 20mm x 10M 5rl/cs



_Krystol Plug

Krytonite Swelling Waterstop is a synthetic rubber waterstop that uses swelling pressure to seal concrete construction joints and stop water.

Krytonite has superior swelling pressure and performance that stops water better than bentonite and competing swelling waterstops. It is suitable for use with regular ground water as well as salt and sulfate contaminated water. Krytonite is extremely durable and will not deteriorate over time. It can be used by itself as a single protection waterstop, or with other components of the Krystol Waterstop System as a double or triple protection option for construction joints.


  • High-performance swelling – even in contaminated water
  • Flexible and easy to install
  • Resistant to high hydrostatic pressure
  • Extremely durable – will not deteriorate even with repeated wetting and drying cycles
  • Innovative trapezoid shape resists dislodgement and allows better concrete consolidation
  • Controlled swelling allows for concrete strength development in advance of swelling pressure


Use Krytonite Swelling Waterstop to permanently waterproof horizontal or vertical construction joints, pipe penetrations, between precast elements and other concrete joints. Not for use at expansion joints. Suitable for use in sewage and containment structures. May be used in areas with chloride or sulfate contaminated soils and in contact with sea water. Use in conjunction with Krystol Waterstop Treatment or as a replacement for bentonite strips.
