AccuCast WP-49 is a silane based liquid water-repellent admixture that is mixed throughout the concrete mix of normal, medium, lightweight concrete block, and ready mixed concrete.

AccuCast WP-49 provides resistance to water penetration by reacting with the cement to form strong water repellency throughout the masonry units and concrete structures within. Saline based chemistry is proven to effectively prevent moisture from penetrating concrete masonry walls and concrete structures.
