Before you build your own fire pit, you need to make sure it is OK that you make your fire pit based on the laws regarding creating structures like this on your property. Once you have the green light to make your fire pit on your residence grounds, the next part is gathering up the necessary supplies. In order to build your own fire pit, you will need to comparison shop and price tools and materials, such as bricks, trowels, cement and shovels.
When you wish to make a fire pit in your background, there are several ways to accomplish this task. Below you will find one set of step-by-step instructions to approaching this fun and exciting do-it-yourself home improvement project.
- Identify where you would like to make your fire pit and insert a wooden rod into the center of this location. To the rod, attach a 10 1/2 -inch string with a can of spray paint at the end. While holding the string tight, spray-paint a circle. Next, connect a 22 1/2-inch string to the same spray can and draw another circle. Using these guidelines, dig a trench that measures 10 inches deep and 12 inches wide.
- Next, place 2 inches of gravel about the trench to create a lining. Tamp the gravel, making it firm to the touch. The gravel will then be covered with concrete that reaches ground level. Using a shovel can eliminate air pockets. Level this area with a piece of 2×4, followed by trowel smoothing. Allow the concrete to harden and then cover it with plastic. This should set for a couple of days with an additional week of open-air curing.
- Once the concrete has cured, use water to create a mist and smooth out the mortar. Next, press a manhole block measuring 6 inches into the mortar, followed by another piece lying flush against the first. Scrap pieces of 2 x 4 can be used to keep the tops of the blocks in an even pattern. Leaving three equidistant 3/4-inch gaps creates air vents within your fire pit.
- Continuing to build your own fire pit, you will dry-lay a second layer of 6-inch manhole blocks over the first. Mortar is not used during this step. The blocks should be positioned so that they are flush with one another. Internal edges of this second layer should line up with the bottom layer. A slight lip will begin to form on the outer edge.
