Rely on the concrete style of foundation blocks Most builders looking for standard foundation blocks will select concrete blocks, which are a combination of concrete, sand and gravel poured into a mold. Industry insiders call concrete blocks concrete masonry units (CMU). Concrete blocks are available in several standard sizes, 8', 10' and 12', but local building codes and builder preference will determine which foundation blocks you should choose.

I recommend:  Watkins Concrete Block of Omaha is a foundation blocks provider manufacturing more than 1,300 different block products. Akron Brick and Block is an Oldcastle company offering a variety of foundation blocks.

Consider architectural foundation blocks for a different look Foundation blocks don't have to be just gray utilitarian objects. Block manufacturers have answered the call for building products that are functional yet attractive. You can find architectural foundation blocks in a wide array of colors, shapes and textures to suit your aesthetics as well as your building requirements.

I recommend:  Beavertown Block manufactures architectural concrete masonry units in finishes such as sandblasted and split faced concrete blocks. Anchor Concrete Products include a weathered-face architectural foundation block.

Look at unconventional options for concrete foundation blocks Manufacturers keep coming up with new ways to make building easier, and foundation blocks are no exception. Precast autoclaved aerated concrete or PARC, popular for years in Europe, is now available in the Southeastern states. Another product hearkens back to olden days with rockface block, which was common before the invention of the concrete or cinder block.

I recommend:  PARC is a lightweight, solid concrete block that presents an alternative to standard building methods, offering durability and good insulation. Safecrete is a brand of PARC blocks offering energy efficiency, fire resistance and a light weight. Classic Rockface Block is great for historical restoration projects.
