Colorado Best Block is a manufacturer and distributor of concrete masonry units, or CMU, which are large concrete blocks made from cast concrete. They include aggregates such as scoria, expanded shale, pumice, sand, and fine gravel. The ratios of these aggregates can be manipulated to achieve a variety of standard colors, custom colors, and densities. Due to the demanding and diverse market, our concrete masonry units are manufactured to meet the strength, fire rating, and acoustical expectations of the National Concrete Masonry Association and may be designed for use as both structural and finish walls for a variety of commercial and residential applications.

There are two main product lines: Standard Block Products and Architectural Block Products, which are both regularly tested for load-bearing capacity, temperature fluctuation, and material consistency. The Standard Block Products are smooth and come in a variety of sizes for your building needs. Architectural Block Products are also offered in a variety of sizes and have different surface finishes or textures including Split Face, Ground Face, and Scored block, which make them ideal for any aesthetic design! In addition to block, Boral offers a selection of Masonry Accessories and products to complete your whole masonry project.
