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.
