DRY BLOCK

DRY-BLOCK is a complete system of liquid polymeric admixes, one mixed throughout the concrete during manufacture of the block, the other during the preparation of the mortar. As the concrete dries, polymers cross-link becoming permanently "locked" into the units for long lasting resistance to water penetration.
DRY-BLOCK has revolutionized concrete masonry by making it possible to build beautiful split-face rock and concrete block buildings without the worry of wet interior walls. The result? Good looking buildings at a competitive price.

Being an integral part of the block makes all the difference between DRY-BLOCK and conventional surface sealants. Producers choose color that is integral to the block so that it's aesthetic qualities endure without frequent maintenance. The same holds true for DRY-BLOCK which retains it's water repellency without maintenance.

• Only proven integral water repellent system for block and mortar
• Only liquid polymer water repellant that permanently interlocks with the masonry material.
• Only integral water repellant to pass ASTM E 514 Wind Driven Rain Water Permeance with a Class E rating and ASTM E 72 for full wall flexural bond strength.
