Krystol Plug™

As part of the Krystol Leak Repair System, Krystol Plug is a rapid-setting hydraulic cement product that when mixed with water is used to stop flowing water and repair leaking cracks, holes and joints in concrete.

Krystol Plug sets hard within 2 minutes and has high-compressive strength, which allows it to stop water even under high-hydrostatic pressure. Stopping water flow then allows permanent repair of the leak using Krystol technology.

How it works

Krystol Plug is mixed with water and immediately, and firmly, pressed into a prepared chase to stop flowing water. After stopping the water, Krystol Repair Grout is used to introduce Krystol technology to the leak repair. 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.
