List of Cinder Block Fire Pit Ideas
1. Simplistic Pit
You don’t have to build a complicated fire pit to achieve a unique design. A fire pit can be simplistic, yet elegant. If you want to build a temporary cinder block pit that’s simple and beautiful, this pit design template is for you.
This design idea will allow you to easily build a spacious circular cinder block fireplace on a stone gravel floor. With this kind of floor, you can chuck firewood into the fire without issues.
– Required Tools
You need some fireproof cinder blocks, paver/gravel, shovel, marking paint, mallet, a long piece of wood, and a landscape adhesive. If you have old cinder blocks lying around somewhere, ensure it is porous. Porous cinder blocks allow airflow; if they aren’t, the blocks’ heat-resistant level will drastically reduce, and an explosion could ensue.
– Building Process
The first step is to check if fire pits are legal in your area. If they are, decide where you would like to install them. Make sure the place is about 20 feet away from overhanging trees to prevent accidental fire outbreak.
Mark the circle with marking paint and dig up around the marked area a few inches in depth. Ensure the center circle is leveled. Use a long piece of wood to ensure this.
Next is to pour the paver base into the center circle and put the blocks in the dug hole. Hit the blocks with a rubber mallet to help them settle into the ground. Apply landscape adhesive on each block to allow the next layer of blocks to stay in place.
Once the blocks have been set down, fill the fire pit with granite rocks to allow drainage if it rains. This is also done to prevent weeds from growing. However, you must wait for a few days for the adhesive to dry before using.
2. Round Fire Pits
Round fire pits are beautiful and a popular choice due to their sense of hospitality. Building this fire pit is quite easy, but we recommend building it on a gravel pad and creating a comfy space for sitting.
A couple of Adirondack chairs placed around the fireplace with surrounding lights will be a fantastic addition. Another option is building it on grass. You can use metal wires and plywood to solidify the concrete. Turn your winter night into a magical scene with this pit design!
– Required Tools
You need a gravel pad, which can be optional too, cinder blocks, marking paint, metal wires, and lava rocks. You can use plywood in place of metal wires.
– Building Process
First, choose the site and draw a ring on the ground. Then, you must tamp the ground and place a gravel pad on it. Alternatively, you can discard the pad and build on grass.
Make sure that you arrange the first layer of blocks in a ring so that each corner touches the other. The holes should face skyward to allow air. However, remember to use metal wires or plywood to solidify the blocks, which is an important step. Then, you must add more layers to reach the desired level, as you would pour lava rocks inside.
3. In-ground Block Fire
The in-ground cinder block fire pit is ideal for those who want a low-profile cinder block fire pit. It is simplistic in design but requires some effort to dig into the soil to the desired level to install the cinder blocks. The advantage of doing this is that the wind won’t be able to sway the flames at will.
– Required Tools
Building this fire pit requires gravel, cinder blocks, and adhesive gum. In addition, you also need a shovel to dig the soil.
– Building Process
Dig out three to four inches of soil and fill the center of the soil with gravel, after which you must level it up and lay the first row of cinder blocks.
Next is to add more layers until you attain the desired height. They should be positioned in a straddled way. Finally, once the height has been reached, you must seal the blocks with mortar and allow them to cure for some days before use.
