“CMU” stands for concrete masonry unit — a standardized, precast rectangular block used in several construction applications. Construction in any form requires reliable, durable and cost-effective materials. In addition to fulfilling these requirements, CMUs are easy to install and provide a flexible option for design and construction.

Concrete masonry units are a great alternative to traditional brick or stone. They are also known as CMUs, and they are manufactured from cement and other ingredients to form a solid, durable block. CMUs are used to create walls and floors in both residential and commercial structures.
