KRYSTOL Waterstop System

The Krystol Concrete Waterproofing System is an "in-depth" concrete treatment that is applied to the surface of existing concrete structures. Krystol T1 and Krystol T2 are the first and second coats of this two-coat system. Supplied as a dry powder, Krystol is mixed with water to a slurry and applied to the inner or outer side of the concrete structure with a brush, broom or spray equipment. In the presence of water, the special chemicals in Krystol will react with the concrete and will grow millions of long, needle-shaped crystals deep into the concrete mass. These crystals will 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 is not required to remain intact for the system to be effective. As a result, the Krystol system is extremely durable and will last the lifetime of the concrete.
