Not only does charcoal grilling make food taste better, grilling out is often a focal point for outdoor gatherings for friends and family during the warmer months. Also, building your own charcoal barbecue will save money, and give you the satisfaction of knowing that you built your grill by hand. When building a charcoal barbecue, it's important to place it on the corner of a patio to ensure a solid base. All it takes to complete the project is a sunny weekend.
Measure the desired area, using a measuring tape. The footer should be a 4-by-8-foot rectangle and 6 inches deep. Use chalk to mark the measurements.
Mix the fibre-reinforced concrete mix and make the footer. Put down the concrete mix within the 4-by-8-foot rectangular measurements. The concrete forms the base of the barbecue.
Draw an outline of the barbecue with the chalk once the footer--or base--has dried. It's important to leave 2 inches open all around the footer. Begin to lay down your bricks within this outline. Dry-lay the first two courses of the bricks to ensure that the pattern you are using will work.
Prepare the mortar mix and begin to build the barbecue at the corners. Add mortar to the base to bond the first set of bricks to the footer. Build the bricks up four courses high, filling in from corner to corner.
Spread a thin layer of gravel inside the bricks, followed by a 4-inch-thick slab of the concrete mix. While adding the concrete, use a hand level to keep the rows of brick level, as well as the wall. If you have used too much mortar, chip off the excess with a trowel.
Insert 4-inch lengths of rebar in the fresh mortar joints. This rebar will support the rectangular grill grate you will add once the charcoal barbecue is completed.
Add bricks to finish the charcoal barbecue, at least 4 courses high. This will act as a "backsplash" or back wall of the grill.
