Hello, I am having some issues figuring out how to get my block crawl space to work with brick. For example, first layer is the footer, followed by 3 rows of 8 inch block, with a row of 4 inch block. This allows for about 3 5/8 inch for the brick to sit on. However, I cannot figure out how to do this with my options. I have no problem with the footer and 8 inch block, but how do I get the last row for 4 inch block with brick? Is there a catalog somewhere to download 4 inch block to allow for brick? Thank you, Jeff S. O.
