Krystol Waterstop System

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.

Product Benefits

• Flexible and easy to install using Krytonite Adhesive
• 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
• High-performance swelling – even in contaminated water

 

World of applications 

Use Kryton’s joint waterproofing system to waterproof and protect:

• Static concrete-to-concrete joints where there is any concern regarding water penetration
• Preplanned and unintended shotcrete cold joints

Krytonite Swelling Waterstop is the ultimate solution for waterproofing concrete construction joints. Krytonite is used instead of conventional swelling waterstops, or as part of the Krystol Waterstop System (KWS). Through its unique synthetic rubber technology, Krytonite swells up to 4 times more than ordinary rubber or bentonite swelling waterstops, and produces enough swelling pressure to withstand extreme hydrostatic pressure - even when exposed to salt water or when used in chloride or sulfate contaminated soils. Despite its extraordinary swelling ability, Krytonite is specially engineered so that swelling action occurs after concrete has gained sufficient strength. This controlled swelling eliminates the risk of cracks or voids in the concrete that may occur if swelling was uncontrolled. Krytonite is easy to install and its innovative trapezoid shape resists dislodgement during concrete or shotcrete installation. Its unique shape also allows better consolidation of the concrete around the waterstop, while the bright yellow color makes for easy inspection. Krytonite provides confidence that your projects jointing system will be waterproof for the life of the concrete.

What makes krytonite better?• proven water stopping performance to 0.8 mpa(8 bar)• forms to contours found in the concrete• quick and easy installation• innovative trapezoid shape resists dislodgement,And allows better concrete consolidation• controlled swelling allows for concrete strengthDevelopment• bright yellow color makes inspection easy• when used in conjunction with krystol internalMembrane (kim), and as part of kryton’s single,Dual or triple protection krystol waterstopSystem (kws), krytonite provides the ultimateCombination of immediate and long-termWaterproofing Bentonite waterstop
Bentonite-based hydrophilic waterstops are madeFrom clay and have a capacity for expansion ofJust 1 or 2 times their original volume. Due to their
