Use this guide to plan and build the base of our barbecue bar
Set the next block in place and push it against the first block so that the joint between them is about 3⁄8 inch. Check the block for level.
Scrape mortar onto the flanges of the laid blocks and set the next course of blocks on top. Start the next row with a corner block or a half block, so the blocks will be stacked one on top of two. Check this row for level and see that the blocks form a straight line. Scrape mortar from the joints as you work.
