What Choices Do I Have With Concrete Blocks?


Concrete Block Sizes and Colors:

Concrete blocks come in a variety of sizes and colors to meet the design requirements of any project. Please visit each concrete block type above to view the available colors and sizes. Custom or special order concrete block orders are run on a per-job basis. Expect a 4 to 6 week lead time. Minimum quantity production order and/or mold fees may be required. Our manufacturing capabilities extend beyond what is listed, so if you need something special, just let us know.


Structural & Non-Structural Concrete Blocks:

Structural concrete blocks conform to ASTM C90, Specification for Load-bearing Masonry Units, Medium Weight. These units also follow the latest editions of ACI 530, and Chapter 21 of both the California Building Code (CBC) and the International Building Code (IBC). To achieve industry standard Medium Weight, RCP Block manufactures its concrete blocks with black volcanic cinders that conform to ASTM C331, Specification for Lightweight Aggregates for Concrete Masonry Units. Different weights and design strengths are available on Special Order. RCP Block & Brick’s non-structural concrete masonry units (CMUs) conform to ASTM C129, Specification for Non-load bearing Concrete Masonry Units.
