Xypex is a unique chemical treatment for waterproofing and protection of concrete. The active chemicals react with moisture of fresh concrete causing a catalytic reaction which generates a non-soluble crystalline formation of dendritic fibres within the pores and capillary tracts of the concrete. Thus the concrete becomes permanently sealed against the penetration of water or liquids from any direction
