Krystol® Technology Kryton’s line of concrete waterproofing products use a unique and proprietary blend of Krystol chemicals. Krystol is based on principles that are very similar to the processes that occur during the hydration and hardening of concrete. When cement particles are mixed with water, a chemical reaction occurs where the calcium silicates in cement combine with water to form new compounds. The new compounds are calcium silicate hydrate (CSH) and calcium hydroxide. The CSH forms as an amorphous microcrystalline structure, extending outward from the individual cement particles and...

THE MOST EFFECTIVE CONCRETE WATERPROOFING SYSTEM IN THE WORLD. Only Kryton protects concrete permanently. Our revolutionary self-sealing technology and comprehensive support system transform concrete into an ever-vigilant, waterproof barrier. Short term, you’ll shave weeks off construction schedules, cut waterproofing costs by up to 40% and maximize your building footprint. Long term you’ll avoid leaks, discoloration and costly callbacks. All of which explains how we can offer an industry leading 25-year warranty. And how nearly 40-year-old Kryton projects are as dry today as when they were first...

Krystol Internal Membrane™ (KIM)® Krystol Internal Membrane or KIM is an integral crystalline concrete waterproofing admixture. When combined with water, KIM’s proprietary chemicals react to form millions of needle-like crystals. These crystals grow and fill the capillary pores and micro-cracks in the concrete, blocking the flow of water. As time passes and stresses form new cracks, any incoming moisture causes the crystals to reactivate – ensuring continuous waterproofing over the years. KIM is used in place of externally applied surface membranes to protect against moisture transmission, chemical...

Permeability Reducing Admixtures The most recent version of ACI 212.3R-10: Report on Chemical Admixtures for Concrete includes a new chapter specifically about permeability reducing admixtures (PRA). PRAs can be divided into two categories: • PRAN – Permeability Reducing Admixture for Non-Hydrostatic Conditions • PRAH – Permeability Reducing Admixture for Hydrostatic Conditions Previous (Informal) Waterproofing Admixture Current (Formal) Permeability Reducing Admixture Hydrostatic Conditions (PRAH) Damproofing Admixture Permeability Reducing Admixture Non-Hydrostatic Conditions (PRAN) Notes*...

KRYSTOL INTERNAL MEMBRANE Concrete Waterproofing Admixture compared to other technologies KIM Concrete Waterproofing Admixture Water Repelling Admixtures Densifying Admixtures & Water Reducers Surface-Applied Membranes & Bentonite Resists high hydrostatic pressure Yes. Proven up to 140 m (460 ft) of head pressure. No, but will resist water penetration at low pressures. Possibly, but provides no protection at joint and crack locations. Easily compromised by a single puncture or imperfect seam. Shortens construction schedule These products come included in the concrete when it is placed. There...

Krystol Broadcast™ Krystol Broadcast is a crystalline waterproofing treatment for concrete flatwork that is applied dry to the fresh concrete surface and troweled into the concrete during the final finishing. Krystol Broadcast features a unique fugitive dye that highlights where the powder hits the concrete to ensure uniform distribution. The proprietary Krystol chemicals penetrate deeply into the concrete mass protecting it against water access. Krystol Broadcast Packaging 25 kg (55 lbs) resealable pails • Permanently waterproofs the concrete • Withstands extreme hydrostatic pressure • Protects...

Krystol T1® & T2® Waterproofing System Concrete Waterproofing for existing Construction Krystol T1 & T2 System is an “in-depth” concrete treatment that is applied as a slurry, spray or dry-pack to the surface of existing concrete structures. In the presence of water, the special chemicals in Krystol will react with the concrete to grow millions of long, needle-shaped crystals deep into the concrete mass. These crystals permanently block and prevent the passage of water through capillary pores, micro-cracks and joints. The concrete itself becomes the waterproof layer and the surface treatment...

Krystol Mortar Admixture (KMA)™ Krystol Mortar Admixture is specially formulated to provide long-term protection in cementitious mortar by reducing both permeability and absorption. Building Mortar and Concrete Masonry Units maintenance and repair costs can be significantly decreased by improving durability and by preserving the original appearance. It contains Kryton’s unique and proven Krystol technology to simplify installation and provide superior performance such as the ability to self-seal minor cracks and withstand water under pressure. Krystol Mortar Admixture • Lowers upfront building...

Krystol® Waterstop System Using Kryton’s proven integral crystalline waterproofing technology, the Krystol Waterstop Construction Joints System forms an impenetrable, watertight seal at all joints. Comprised of two products, Krystol Waterstop Grout and Krystol Waterstop Treatment, the Krystol Waterstop System succeeds where others fall short. For maximum results, Krystol Waterstop Treatment and Grout should be used together. By applying the Grout in a triangle-shaped strip, allowing it to cure and then using a layer of Krystol Waterstop Treatment, the Krystol technology immediately goes to work...
