It’s an intelligent, self-sealing waterproofing system that transforms porous concrete into a permanent, water-resistant barrier. The Krystol Concrete Waterproofing System™ uses advanced integral crystalline waterproofing technology to provide a powerful, guaranteed defence against water damage and the corrosion of steel reinforcements. When combined with water and concrete, Krystol™ reacts with unhydrated cement particles to form millions of needle-like crystals. Over a period of weeks and months, these crystals grow, filling the naturally occurring pores and voids in concrete, and permanently blocking the pathways for water and waterborne contaminants.

Later, if cracks form due to settling or shrinkage, incoming water triggers the crystallization process and additional crystals begin to grow, filling cracks and ensuring that the structure’s waterproofing barrier is maintained and protected.

By eliminating the need for external waterproofing membranes, the Krystol Concrete Waterproofing System saves construction time and costs. It provides maximum flexibility and can be used any time before, during or after the construction process. Unlike external waterproofing membranes, Krystol will not deteriorate. It lasts the lifetime of the concrete structure.

The Krystol Concrete Waterproofing System is ideal for pre-cast, shotcrete and cast-in-place applications. It’s suitable for a diverse range of products, including above ground and below-grade parking facilities, bridges, dams, tunnels, basements and foundations, wastewater, sewage and water treatment tanks, swimming pools and hot tubs.

Krystol technology has been used successfully for over 30 years in 40 Countries to 35 years. And it’s guaranteed for your peace of mind. Whether you’re building a new structure, upgrading an existing one or repairing cracks, the Krystol Concrete Waterproofing System helps build quality, reliability, durability and cost-effectiveness right into the concrete.
