Penetron
crystalline waterproofing coating
Penetron is a waterproof , spreadable crystal mortar for basement waterproofing , which seals the concrete in depth. It consists of Portland cement, quartz sand and active chemical compounds. When applied to the concrete surface, the active compounds react with the moisture of the concrete, causing a catalytic reaction, which produces insoluble crystals.
Penetron allows water vapor to penetrate through the concrete.
