Kryton Krystol Repair Grout™

Krystol Repair Grout™ is a high-performance crystalline waterproofing grout designed to permanently repair leaking cracks, holes, joints, and deteriorating concrete surfaces. As part of the Krystol Leak Repair System, it transforms damaged concrete into a durable, watertight barrier using Kryton’s proprietary Krystol® technology. This technology reacts with water and unhydrated cement particles to form insoluble crystals that seal capillary pores and micro-cracks, ensuring long-term waterproofing—even under hydrostatic pressure.

Engineered with advanced fiber reinforcement and shrinkage-controlling additives, Krystol Repair Grout offers exceptional crack resistance, high bond strength, and durability. It’s ideal for resurfacing rough or spalled concrete, patching honeycombs, sealing tie holes, and waterproofing concrete block walls. Once hardened, it resists rain, foot traffic, and chemical attack, and is certified safe for potable water contact (NSF/ANSI Standard 61).

Krystol Repair Grout can be applied on both the positive and negative sides of water pressure and is suitable for use in wastewater treatment tanks, parking garages, tunnels, and marine structures. By eliminating the need for external membranes, it supports sustainable construction and reduces lifecycle costs.
