Proven protection for moisture control
in masonry construction

With the longest successful track record of any integral water-repellent, the DRY-BLOCK® System is the most extensively used integral water-repellent admixture system in single-wythe concrete masonry construction.

DRY-BLOCK® System
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.
