Penetron Crystalline Waterproofing

Penetron Crystalline Waterproofing


A surface-applied, integral crystalline waterproofing material, PENETRON is used for waterproofing and chemical protection at both above and below ground level.


PENETRON is applied by brush or spray to either the positive or the negative side of the concrete and in the presence of moisture penetrates deeply into the structure. The ensuing chemical reaction fills microcracks, pores and capillaries with an insoluble crystalline formation, which prevents water and water-borne chemicals from entering, even under high hydrostatic pressure. Cracks that develop during the lifetime of the concrete are self-healed by PENETRON, resulting in permanent concrete protection.
