What are integral water repellents? - I·A

A. Integral water repellents are usually polymeric liquid admixtures incorporated into concrete masonry units during manufacturing to reduce the wicking characteristics of the units. As such, they make masonry materials hydrophobic by limiting the amount of water that can pass through the masonry due to capillary suction (wicking).
