Krytonite™ Swelling Waterstop

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.

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.
