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. When applied to concrete, Krystol chemically reacts with water and un-hydrated cement particles 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. Any moisture introduced over the lifespan of the concrete will initiate crystallization, ensuring permanent waterproofing protection.
How It Works
Use in conjunction with Krystol Plug to repair any leaking crack, joint or other defect in concrete, or by itself to repair spalled or honeycombed concrete.
- Crystalline waterproofing technology

First, stop any flowing water with Krystol Plug. Mix Krystol Repair Grout to a dry putty consistency (approximately 4 parts of powder to 1 part clean water by volume) and pack the keyway. Additional powder may be used to produce a thicker grout suitable for vertical repairs. Protect application from damage by rain, rapid drying or freezing for at least 24 hours.
