Self made fire pits can complement accessories gathered from home improvement stores. However there is nothing like constructing it in the original way. You can use plain landscaping blocks or stones. A few decide to use concrete blocks. Although this tends to get deteriorated with heat, however worth using as changing them is not costly. Drainage is an important part of domestic fire pits. You can dig a 3 4 inch hole 24 inches. Then fill it with gravel. This hole requires to be dug right in the bottom center of the pit. It is supposed to work like a sump and let the water drain. You have to dry stack the stone first. The dry stacking is as well useful for replacing cracked or broken stones. A few opt to cement the courses by laying cement on exterior half. This is considered useful for shielding the cement from high temperature.
Here are a few other things required here, retaining wall blocks, steel pit ring with tabs, metal grate, sand and gravel. Ring and grate are necessary things when constructing a fire pit at home. This can be found at home improvement stores or near garden stores. At times it is easy to buy these online. The width of the wall blocks used here can be 12 inches wide, 4 inches high and 8 inches deep. Put a substantial amount of sand and gravel in the pit.
Dig a hole at this moment. This hole is supposed to be 2 feet wider than the fire pit. Dig the hole around 7 feet diagonal to the fire pit. The hole is supposed to be round. To make it so, mark the circle. Dig out 1 foot of soil. Then dig for four inches of gravel plus four inches of sand. That layer is required to be compressed flat, next work with the base course of blocks. It has to be laid down and you have to level it carefully. The space out of the blocks has to be filled; you can fill it with gravel. The first course will be more or less buried this way; this in turn will strengthen the stone base.
Now you have to focus on laying more helpings of stone. At this point you will draw on the steel ring. The ring should keep the grill intact. This is done to confirm that each of the helpings is round with precise diameter. The ring has to be made vertical to each other and to the ground surface. If you notice that the center of your pit is roughly 36 inches in diameter you will recognize you did well. At this point you can overlap the stone layers. In each of the helpings, you are supposed to leave 3 4 openings between stones. The openings are planned to let air to flow in and help the fire burn.
Given that by now the entire job is finished, it is now time to lay the last helping of stone. Ahead of the final helping is laid; the steel ring has to be placed in the spot. As a standard guides, a fire pit constructed this way can have 7 layers. Your pit constructed this way is supposed to be 24 inches high. For better results from your fire, you can take out a layer or two.
