Krystol Cementitious Crystalline Waterstop Treatment

Krystol Waterstop Treatment™

Krystol Waterstop Treatment is a specially formulated compound containing integral crystalline waterproofing.

Krystol Waterstop Treatment™ is a cementitious crystalline slurry that is applied to horizontal and vertical construction joints to provide additional waterproofing protection, and protect rebar from corrosion.

Krystol Waterstop Treatment™ is used in conjunction with Krystol Waterstop Grout and/or Krytonite, as part of the Krystol Waterstop System, wherever water penetration through static concrete-to-concrete joints is a concern. Krystol Waterstop Treatment™ can also be used by itself as a dampproofing treatment.

How It Works

Krystol Waterstop Treatment™ 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.
