Krytonite™ Swelling Waterstop
Krytonite Swelling Waterstop is a hydrophilic synthetic elastomeric rubber waterstop that uses swelling pressure to seal concrete construction joints and penetrations to stop water in the most extreme conditions. Krytonite has superior performance that swells up to 10x its original size and up to 4x more than competing bentonite and rubber swelling waterstops. For use with regular ground water, 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 for construction joints and penetrations.
FEATURES & BENEFITS
- High-performance swelling up to 10x original volume
- 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.

Before using this product, refer to Application Instruction 4.11, 4.15 or 4.16 (as applicable).Basic Application Procedure: Using Krytonite Adhesive, or other approved fastening device, adhere Krytonite Swelling Waterstop at or near the center of the construction joint to clean dry concrete surface. For added long-term protection of the outboard reinforcing steel, apply Krystol Waterstop Treatment to the concrete surface first and adhere Krytonite to the treatment when it is dry. Strip-ends should be tightly butted and not overlapped. Avoid rain or immersion in water as this may cause premature swelling. If premature swelling occurs, dry the Krytonite sufficiently to restore its original dimensions and ensure material is properly affixed to the surface before pouring concrete.
