Dry Blocks

Dry Block is a complete system consisting of 2 liquid polymeric admixtures. One admixture is included into the mix design of the concrete during the manufacture of the CMU; the other, a mortar admixture, is added to the mortar during the mixing process prior to the wall being laid. Dry Block is a long-lasting integral water repellent system that stops the capillary action of moisture wicking through the CMU or mortar. This system prevents the entrance of moisture into the building through the wall. The Dry Block system can be added to any color, shape, size or texture of our Concrete Masonry Units. Please request a current Dry Block qualification certificate prior to specifying. Westbrook Concrete Block has been a certified Dry Block producer since 1989.
