Permaquik® 200 Crystalline Waterproofing - 5 Gallon Pail

About this product

Permaquik® 200 Crystalline Waterproofing is a capillary waterproofing formulation of proprietary blends of chemicals, quartz sand and cement. The chemicals contained in the crystalline waterproofing materials require the presence of moisture to set off a chemical reaction from within the matrix of the concrete. When combined with "free lime", these chemicals form long chained complexes, which crystallize and penetrate deeply into the capillaries of the concrete, eliminating the migration of water. Independent tests show penetration up to 2 inches (51 mm) in 28 days. The crystalline process is continuous as long as moisture is present in the concrete, significantly reducing the concrete's natural porosity by filling small voids and cracks caused by shrinkage. The concrete is still able to breathe as the crystalline will lie dormant until moisture reappears and then will reactivate to seal the cause of the leakage. Permaquik® 200 is applied as a slurry coat on vertical interior or exterior (CIP) concrete or (CMU) block structures to create a waterproofing barrier from within the substrate. It can be applied by "broadcasting" the dry powder onto horizontal concrete surfaces at the time of initial set and power- or hand-floating the powder into the green concrete. Once the reaction has taken place and the formulated has crystallized, these coatings are highly resistant to salts (chloride penetration), alkalis and seawater. Because of the density of the crystalline chain, the concrete is able to withstand mildly acidic conditions to provide protection in wastewater treatment plants as well as superior protection against frost damage and may also be used in sealing the joint between new and existing concrete.
