Dry Block
A Dry Block is a hollow CMU designed for moisture-resistant construction, making it ideal for projects where water absorption and durability are critical. Dry Block CMUs are widely used in institutional, residential, and commercial settings where moisture control and long-lasting performance are a priority. Visually, dry block CMUs resemble standard concrete blocks, but they have a dense, less permeable surface feel, offering added protection against water intrusion.
