Krytonite™ Swelling Waterstop

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

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

Application Instruction 4v2

How it works

Krytonite Swelling Waterstop is adhered using Krytonite Adhesive at or near the center of the construction joint to the clean, dry, concrete surface. For added long-term protection of the outboard reinforcing steel, apply Krystol Waterstop Treatment to the concrete surface first and then adhere Krytonite to the treatment. Once this is completed, pour the concrete over on the Krytonite making it part of the concrete structure.

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