Krystol Repair Grout™
DESCRIPTION
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.
FEATURES & BENEFITS
- Crystalline waterproofing technology
- Simple and easy to use
- Non-shrink crack resistant
- NSF 61 Certified; safe for contact with potable water
- Color matches concrete
RECOMMENDED USES
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.
