Standard Masonry Units

Nettleton Concrete has over 60 years of experience producing quality concrete masonry units (CMU). Concrete blocks are manufactured from cement, either dense or lightweight aggregates, and water which is mixed, molded, and cured. These are used extensively for both loadbearing and non-loadbearing walls. Lightweight concrete units have excellent insulating properties against transfer of heat and continue to be an integral part of new construction.

Our CMU consistently meet or exceed ASTM specifications and our customers' expectations.
