Does Xypex add Durability & Protection?
Impermeability against liquids. 50mm thick Xypex treated concrete has withstood hydrostatic pressure equivalent to 405 feet of head pressure. This was the limit of the testing apparatus. Xypex treated concrete is impervious to: water, chlorinated water, diesel, fuels and other petroleum products. As the crystals are a silica, which is a mineral and not an organic product, Xypex significantly increases the chemical resistance of concrete. Numerous tests have shown that Xypex treated concrete is not affected by a wide variety of aggressive chemicals. Xypex protects concrete against chloride attack. The growth of Xypex crystals into the concrete will help protect reinforcing steel by blocking microcracks and capillary pathways used by migrating chloride ions. The concrete becomes impermeable and prevents further entry of chlorides or other chemicals. Normally during the course of spalling repairs to concrete structures, chlorides are still trapped and active within the concrete in areas w
