A masonry barbecue can be a great freestanding backyard feature or the cornerstone of an entire outdoor kitchen in your garden or patio. Before you make a masonry barbecue it is important to follow a few guidelines. First, carefully select a location for your barbecue. Ideally, a masonry barbecue should be built in a place where there is plenty of ventilation. Also, the barbecue should be in a location that has maximum shelter from wind, dust, and dirt. Usually, a patio is ideal for making an outdoor masonry barbecue, although you'll want to be sure it is clear of any flammable materials such as trees, clotheslines, and the patio roof. Next, make a concrete foundation and mark a clear parameter for the masonry barbecue. You also may need to consult your local building codes and get the necessary permits before you begin construction. Here’s what you need to do next to build your own masonry barbecue.
Step 1 - Lay the Foundation
The first step to a strong and sturdy barbecue is a strong foundation. First, set a parameter for your barbecue. Then dig a 6-inch deep hole in the parameter for the concrete footing. Right next to it, make a round hole for the chimney. Allow this hole to be at least 6 inches larger than the diameter of the drain pipe. Mix the concrete and pour the mixture into the barbecue pit. Make sure that the sides of the footing are packed in properly and are even. Once you have added the concrete, allow the footing to dry out. Cure it for the next seven days before building the rest of the structure.
Step 2 - Set Up the Drain Pipe
Set up the drain pipe in the hole that you have dug for the chimney. You can also drill holes in the drain pipe to add a rebar so that you can later hang meat on it for curing. This will be convenient when you are using the barbecue for grilling meats.
Step 3 - Make the Chimney
Take a few fire resistant bricks, and using the masonry saw, cut out bevels in the bricks. Now lay these bricks around the drainpipe. The bricks should be lined up properly around the pipe’s curve. Use the mortar to fix them into place and your chimney should be ready.
Step 4 - Fire Pit
The fire pit has to be laid next to the chimney, on top of the concrete foundation. If you are planning to make a round fire pit, you will have to use the masonry saw and make bevels in the fireproof bricks. Lay at least five rows of bricks on top of each other. At this point, you can choose to have a metal top for your chimney. Measure the top diameter for your round chimney and cut a metal piece of the same measurements. If you can do it, get a handle welded onto the cover.
