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, and a minimum quantity production order 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.


Green Concrete Blocks with Recycled Material:

RCP Block & Brick has third party certification by the ICC-ES for recycled content in our concrete masonry units. This shows that when specified to meet USGBC LEED, CHPS, or Cal Green, RCP Block & Brick manufactures a concrete block that will conform to the post-consumer recycled content per ICC SAVE: VAR 1003. Minimum quantity production order may be required.
