If you like to barbecue but do not like the expense of purchasing replacement propane tanks, building your own brick BBQ is a great solution for this problem. A brick BBQ is easy to clean and will add to the value of your home, should you choose to sell it in the future. Building your own brick BBQ is a great weekend project that you can complete on your own and have ready to use by the following weekend.
Shovel out an area in your yard to place your brick BBQ. You may place the BBQ beside your deck, porch or patio for easier access, or set it in a desired location elsewhere in your yard. Wherever you decide to place the BBQ, remember to keep it a safe distance away from your home and make sure the spot is even by using a level.
Determine the height of the BBQ you are building. The height of your BBQ will depend upon where you are placing it. If you are putting it in your yard, build it tall enough for you to cook from comfortably, but if you are building it to sit beside a patio, deck or porch, then you will have to build it tall enough for you to cook from that surface.
Mix up a batch of mortar in a wheelbarrow for easy transport to the site of your brick BBQ. This will also allow you to wash excess mortar away before it has a chance to dry.
Apply mortar to the ground in a one-inch thick layer with a trowel. Apply the mortar in the intended shape of the barbecue. Rectangular and square shapes are easier to find BBQ grill screens for and are easier to place beside a patio, porch or deck, though you can also make a round- or oval-shaped brick BBQ.
Set in the first layer of brick one at a time in the intended shape. You will have to trowel on a bit more mortar at the ends of each brick so that they adhere to the ends of other bricks. Apply more mortar to the tops of the first layer of brick and continue to place one block at a time, layer upon layer until you reach the upper layers.
Lay two blocks in a row that face inward to create a ledge on the opposite sides of the brick BBQ. This ledge will be used to hold the grill screen or rack of the BBQ in place so that it does not fall into the BBQ, and should be located on the row just below the top row. Be sure to do this on the same level on one side of the BBQ as on the other side. Continue to lay the blocks until you have reached the maximum height of the BBQ. Allow the entire structure to dry and cure for a week before use.
Pour concrete into the bottom of a tall brick BBQ so that you have a closer surface upon which to burn your wood or charcoal.
