The Krystol Leak Repair System is a permanent crystalline waterproofing solution used for repairing leaking cracks, holes and joints found in concrete. It reliably stops high water flow, even under high-hydrostatic pressure, and outperforms injection systems. Repairing leaks is a simple 3-step process that involves preparing a chase by chiseling into the concrete, stopping flowing water with Krystol Plug, and then filling the chase flush to the surface with Krystol Repair Grout.

After completing the leak repair, the Krystol T1 Concrete Waterproofing will protect the entire structure against the continued ingress of water and further concrete deterioration, as well as reduce the likelihood of further leaks developing in the structure.

How it Works

The Krystol Leak Repair System 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.
