Crystalline Waterproofing Coating


PENETRON® consists of Portland cement, specially treated quartz sand and a compound of active chemicals. PENETRON® needs only to be mixed with water prior to application. When PENETRON® is applied to a concrete surface the active chemicals react with moisture and the by-products of cement hydration to cause a catalytic reaction which generates an insoluble, crystalline structure. These crystals fill the pores and minor shrinkage cracks in the concrete to prevent any further water ingress (even under pressure). However, the PENETRON® will still allow the passage of vapour through the structure (i.e. the concrete will be able to “breathe”). Even after the concrete has cured, PENETRON® remains dormant in the concrete and will reactivate in the presence of moisture to seal capillary tracts and hairline cracks. In addition to waterproofing the structure, PENETRON® protects concrete against seawater, wastewater, aggressive ground water and many other aggressive chemical solutions. PENETRON® is approved for use in contact with potable water, and is therefore suitable for use in water storage tanks, reservoirs, water treatment plants, etc. PENETRON® is not a decorative material.
