Water is a common enemy to all construction materials. DRY-BLOCK keeps the block dry and offers piece of mind to the owner. A polymeric integral water repellant is mixed into the concrete mixture during manufacturing of the block. An additive is also added at to the mortar at the site by the mason. DRY-BLOCK offers long lasting resistance to water penetration.
How Does It Work?
The DRY-BLOCK® System has been successfully used for over 15 years to provide moisture control of concrete masonry walls. It is the only complete integral system on the market to address the moisture reduction of both CMU and mortar. The DRY-BLOCK® System consists of two separate liquid polymeric admixtures. DRY-BLOCK® Block Admixture is mixed throughout the concrete during manufacturing of the CMU, and DRY-BLOCK® Mortar Admixture is mixed into the mortar. During the curing process, the polymeric admixtures within the CMU and mortar become an integral part of the cement matrix. They become locked into the CMUs and mortar to provide long lasting resistance to water penetration.
