About Concrete Masonry

Concrete Masonry is one of the most versatile building products available because of the wide variety of appearances that can be achieved using concrete masonry units. 

Typically, concrete masonry units have a nominal face dimension of 8” x 16”, available in nominal thicknesses of 4”, 6”, 8”, 10” and 12”.  Certain concrete masonry sizes and shapes are considered standard, while others are popular only in certain regions. Please contact your closest LEE Building Products location for more detailed information on available and custom units.

Standard Specifications for Loadbearing Concrete Masonry Units, ASTM C 90 is the most frequently referenced standard for concrete masonry units.  Please refer to our RESOURCE section for additional technical information.


Why Hi-Performance?​

Hi-Performance CMU from Lee Building Products offer advantages for everyone. The owner benefits from the highest quality CMU which gives the building the highest fire, seismic, and sound absorption ratings while also reducing the energy usage of the facility.

The mason contractor is able to benefit from the efficiency of installing the units which allows them to move through the job more quickly and allow the building to be occupied much sooner.  Meeting or exceeding all ASTM C90 specifications, Lee Building Products would be happy to help you learn more about our Hi-Performance CMU and find out if it is the right direction for your next project.
