Concrete Blocks, a/k/a concrete masonry units, grey blocks or cinder blocks, are one of the most common building materials in the United States. Consisting of basically cement and sand, concrete blocks are strong, durable and fire resistant. The vast majority of architects utilize concrete blocks as the structural material for their commercial and residential building architectural plans. Benefits of using concrete block are its cost effectiveness, durability, low maintenance, and fire resistance.

We produce standard and specialty concrete blocks, ranging in size from 4 to 12 inches in width and 16 or 18 inches in length. Our standard masonry units have an average rating of 3,000 psi compressive strength.
