Krystol Repair Grout™

A crystalline concrete waterproofing product that stops the flow of water to permanently repair leaking cracks, holes, and joints in concrete and to resurface and waterproof defective, damaged, or deteriorating concrete.

How It Works

As part of the Krystol Leak Repair System, Krystol Repair Grout is a crystalline concrete waterproofing product that stops the flow of water to permanently repair leaking cracks, holes and joints in concrete, and can also be used to resurface and waterproof defective, damaged or deteriorating concrete. The grout employs advanced fiber technology and shrinkage controlling additives to prevent cracking.

Krystol Repair Grout contains Krystol technology. Krystol technology reacts with moisture to form insoluble needle-shaped crystals that fill capillary pores and micro-cracks in the concrete and block the pathways for water and waterborne contaminants. Unlike other crystalline solutions that react with free lime that eventually depletes over time, Krystol chemically reacts with water and unhydrated cement particles. Any moisture introduced over the lifespan of the concrete will initiate crystallization, ensuring permanent waterproofing and watertightness protection.

Why Krystol Repair Grout

Proven Over 50 Years

Krystol, introduced over 50 years ago as the first crystallization technology, has proven its efficacy through the enduring longevity of the structures where it was used.

Permanent Reactive Technology

Resistant to rain and foot traffic once hardened. Any moisture introduced over the lifespan of the concrete will initiate crystallization, ensuring permanent protection.

Safe

Safe for contact with potable water and certified to NSF/ANSI Standard 61.

Versatile

Krystol Repair Grout is easy to apply, and crack and shrink resistance. It can be used as part of the Krystol Leak Repair System to permanently repair concrete cracks and leaks for existing construction projects.

Sustainable

By making the concrete itself the waterproof barrier, Krystol technology can reduce the need for additional materials and processes associated with external waterproofing or watertightness methods. This can result in more sustainable concrete over its lifecycle.
