Things You'll Need

Instructions

1

Locate a relatively flat area in your yard and mark out a 40-inch by 56-inch area with marking paint. This will serve as your foundation for the fire pit.
2

Dig a six-inch deep hole inside the marking paint lines. Use a level and a rake to flatten the ground inside the hole.
3

Spread out two-inches of river gravel and tamp it down with a tamper. Make sure the gravel remains flat. This gives you a solid drainage system for your concrete base.
4

Mix Quickrete with water consistent with the packaging instructions and pour the moisture over the gravel. Make it approximately two-inches thick.
5

Line the outside edge of the concrete block with concrete blocks. Position them so the holes in the blocks face up and place the ends of the blocks together.
6

Drive a 5-foot piece of rebar into the ground in the center of the hole in each block. Use a sledgehammer to drive the rebar. When completed, make sure the rebar extends slightly less than two feet above the first row of blocks.
7

Fill the holes in each block with dirt and then place a 1-inch layer of mortar on top of the blocks with a trowel.
8

Add a second row of blocks onto the first row and stagger them to create an interlacing pattern of blocks. Fill those blocks with dirt and add a 1-inch layer of mortar on top with a trowel.
9

Place four pieces of rebar across the 40-inch span of pit. Space them evenly apart from each other. Sink the rebar into the mortar and then smooth the mortar over the ends of the rebar with the trowel.
10

Place a third and final row of blocks on top of the second row. Again, stagger the blocks to create an interlocking pattern.
11

Fill the blocks with dirt and place a 1-inch layer of mortar over the blocks with a trowel. Allow at least 24-hours curing time before using the pit.
