Penetron cementitious capillary waterproofing products are formulations consisting of common cement, quartz sand (of special grade) and multiple activating chemicals that provide the most effective permanent concrete waterproofing
Penetron's waterproofing effect is achieved by the reaction of the various chemical components contained in the solution when combined within the concrete matrix. The compound penetrates deep into the capillary tracts of the concrete by pressure of osmosis and forms crystals that completely seal the capillaries and shrinkage cracks to drive out moisture. The process works with or against the pressure of water. In the absence of moisture, Penetron components lie dormant. Should moisture recur at any time, the chemical action and sealing process repeats itself automatically and advances even more deeply into the concrete. Penetron chemicals will continuously seal and reseal due to their chemical nature. Crystalline growth from capillary waterproofing has been measured as deep as nearly 1 meter from the point of application. Penetron® is 100% compatible with concrete, brick, mortar, and stone.
Penetron is recommended for use in any concrete or block structure where it is required to keep water in or out. Penetron should also be applied to concrete or block structures exposed to potential water or chemical attack and thus requiring permanent waterproofing and protection. Its applicability to either the positive side (side exposed to water) or the negative side (side opposite the water) meets all waterproofing requirements.
