Clayton Block Co., Inc. is one of America's largest manufacturers of gray common units - building blocks. Manufactured under the strictest guidelines, in conformance with ASTM C90, "Standard Specification for Load-Bearing Concrete Masonry Units," Clayton Block supplies the building industry with normal weight, lightweight and 100% lightweight masonry units.

In addition to meeting minimum net compressive strength under ASTM C90 of 1900 psi, Clayton Block has the capability to manufacture high strength units. With our state-of-the-art manufacturing facilities, we continually assess the building industry's needs to meet the demands of today's construction practices.

The need for fire resistance, mold and mildew resistance, sustainability and the ability to meet or exceed requirements for LEED® construction materials are all met with Clayton's masonry products.

In addition to manufacturing concrete masonry units, Clayton Block can supply all the peripheral materials for your project -- anchors and ties, cements, mortars, insulation, and moisture control products, to name a few.

Contact your local Sales Representative or Bob Klee, Technical Director of Clayton Block, to assess your masonry requirements.
