The DRY-BLOCK System consists of two integral water-repellent admixtures and INFINISEAL® DB, a post-applied water-repellent sealer. DRY-BLOCK Block Admixture is mixed throughout the concrete during manufacture of the masonry unit. DRY-BLOCK Mortar Admixture is added to the mortar on site during mixing. The DRY-BLOCK System -- DRY-BLOCK Block and Mortar Admixtures and INFINISEAL DB Sealer -- provides long lasting resistance to water penetration. The system components are available only through Qualified DRY-BLOCK Producers located throughout North America.
DRY-BLOCK® is a complete system of 2 water-repellent admixtures for concrete masonry construction. One admixture is mixed throughout the concrete during manufacture of the concrete masonry unit (CMU) by a qualified DRY-BLOCK producer; the other, a mortar admixture, is added to the mortar during the mixing process.
During the curing process, the polymeric admixtures within the CMU and mortar become an integral part of the concrete matrix by locking into the CMUs and mortar, providing longlasting resistance to water penetration . In addition, DRY-BLOCK Mortar Admixture enhances the bond between the CMU and mortar, further minimizing areas for water penetration into the wall system.
