Foundation blocks are the starting point for many buildings. When used correctly, foundation blocks add strength to the entire structure. A foundation using foundation blocks can be a slab, crawlspace, basement or a combination. Whether or not you can have a basement under the structure depends on the water table and soil conditions.

There are several different kinds of foundation blocks from which to choose, including concrete blocks, architectural masonry units and new innovations. When you're looking for foundation blocks information, a good starting place is your local builders' supplier or foundation blocks provider or manufacturer. They can help you find foundation blocks, give you current prices and product availability and help you estimate your project needs.

When you're evaluating foundation blocks information, consider the following ideas.

1. Weigh the pros and cons of standard foundation blocks versus other foundation block products before you make your decision.

2. Allow a salesperson from the builder's supply to help you decide what product will be best for your project.

3. Get current prices on a foundation blocks list before you place your order.

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.
