First, location, location, location! Start by picking a safe and level spot in your yard. Make sure it’s away from trees, overhanging branches, fences, or anything else that could catch fire. Also, double-check that it’s not near kids' play areas or high-traffic spaces.

Measure out space to ensure it fits the size of your fire pit. Mark the edges with a stick and string line so you have a visual guide for where your blocks will go.

Remove any grass or debris from the area. You will need to clear a space that is roughly 50 inches by 42 inches. This should give you enough space to lay your fire resistant blocks.

Using the flathead shovel, remove any grass, rocks, or debris from the spot.

Lay your first layer of concrete blocks directly on level ground, forming a rectangle. Place 3 blocks flat along two sides and 2 blocks on each of the shorter sides. Make sure the blocks fit tightly together and sit evenly. Adjust the ground underneath as needed to keep everything level.

On the shorter sides where you placed 2 blocks, stand 3 concrete blocks upright on their sides. On the longer sides with 3 blocks, stand 2 blocks upright, leaving a gap on each end to allow air to flow through.

Next, add a second layer of flat concrete blocks using the same pattern as the first. Place 3 blocks along the longer sides and 2 along the shorter sides, making sure they align neatly with the layer below. Keep everything tight and level as you go.

Now that everything is placed the way you want it, apply a layer of mortar mix to the bottom sides of each concrete block that will be standing upright. Carefully set each upright block onto the bottom layer, pressing it firmly into place so it sticks. Make sure each one is aligned properly and stands level—adjust as needed before the mortar begins to set.

Next, apply another layer of mortar mix to the tops of the upright concrete blocks. Then, carefully place your final layer of flat blocks on top, following the same rectangular layout as before. Press each block firmly into the mortar to secure it in place, making sure everything stays level and aligned as you complete the top layer.

Let the mortar set according to the package instructions before using the fire pit.

Grab a few chairs, your firewood, and you’re ready for your first backyard fire!
