At Genest, we have been in the business of manufacturing concrete blocks for over 90 years and have made it our mission to source the best possible materials to exceed industry specifications. As a result, Genest’s high-quality CMUs have become one of today’s most trusted and widely specified block by leading architects, engineers and commercial masons.

Genest has been using less cement in concrete block production than most producers since 1985, and after years of experience and development, we are proud to introduce G-mix®. This low carbon formula uses up to 55% recycled content and half of the cement traditionally used to produce concrete blocks while exceeding ASTM C90 specification requirements. You can be confident that when you specify from Genest, you will have a low carbon footprint for your project.

We built our reputation for quality and consistency one block at a time, and we understand the importance of these factors to our customers. To ensure strict quality control, we select only the finest ingredients: sand, stone, aggregates, color pigments and cement. Our production process uses a computerized mix design and automated production process to maintain consistency. Once complete, our experienced production team inspects each block to ensure it meets today’s strict architectural demands.

Genest Concrete’s Architectural CMUs are available in a large variety of colors, shapes and sizes. Blocks can be produced with textures such as Split Face, Ground Face, Polished, Shot Blasted, Brushed, Split Ribbed, and Blended Color finishes to add to the look and feel of the building. Ask about custom shapes, sizes and colors for endless possibilities.
