Can Cinder Block Be Used For A Fire Pit?
When building a fire pit, the first decision is to choose materials. There are many options, including stone, clay blocks, and marble for the fire pit walls.
While expensive substances like marble and granite are perfect for fireplaces, cinder blocks are a budget-friendly alternative. Clay is far better than other brick-type materials when it comes to maintaining the integrity of the fireplace due to its lengthy presence in fires.
Cinder blocks are also easy to move and work with, making them perfect for DIY jobs. With a variety of block sizes available, they can create any number of shapes for fire pits.
A temporary fire pit can easily turn into a permanent one by using cinder blocks and mortar. The materials needed for this project are readily available at any home improvement store, making the process easy for anyone who wants to give it a try in their backyard.
Are Cinder Blocks Heat Resistant?
Choosing the right materials is essential when constructing a fire pit. To prevent it from crumbling under high heat, ensure that you use bricks about which have been rated for their ability to withstand extreme temperatures.
A cinder block is a porous material, which means it holds and releases oxygen without interruption. This allows the fire to be fueled with fuel without the danger of an explosion or overheating.
Dense materials like concrete blocks aren’t suitable for a project like this, so make sure you find some clay-based fire-rated blocks to ensure the best durability, safety, and resistance.
Tips Building Cinder Block Fire Pit
When building a fire pit out of cinder blocks, there are many factors to consider. The first is the ground site, which must be carefully chosen to ensure it’s not flammable for safety.
And then you decide whether it’s a temporary/permanent fire pit as they have different approaches. The permanent fire pit needs adhesive, which will ensure that its construction is solid.
You also have to consider your backyard space and the shape of the fire pit you desire. If you have a small backyard, around one will be more efficient than a square, or an in-ground fire pit is safer as it has less chance of moving.
So, take the time to carefully consider where you want to build your fire pit and what materials you will need before breaking ground.
Building A Cinder Block Fire Pit
Building a block fire pit is an easy project for DIYers. There are many benefits to building one; they’re affordable, offer years of low maintenance, and allow you to do the things you love with people you care about.
Find out whether building a fire pit is legal in your area, as well as what the applicable fees are and how to prepare for them.
To build the cinder block fire pit, find an appropriate spot for it. This should be at a distance from any plants or structures next to your patio and away from any surfaces that can catch on fire, such as vinyl sidings or wood.
The area chosen for the fire pit must be close to a high-pressure water source, such as a garden hose. This will allow quick access in case of an emergency.
Mark Measurements And Dig Fire Pit
Build a fire pit with a diameter of four feet; this is the average size for residential fire pits. Use any paint that matches your garden’s design to draw the circle in an appropriate spot.
You may also use a shovel for this task, and it will be less time-consuming, but the cut can take longer to create. When you’re done marking out your desired space, take a shovel and dig six inches along that line.
Lay First Layer Of Cinder Blocks
Laying the cinder blocks starts with digging a circular hole in the ground. The hole should be slightly angled outwards, and the holes need to face upwards, with gaps facing up (like you would find on store shelves). With your shovel, push all of the cinder blocks tightly into place so they are flat against one another at once spot.
Lay Second Layer
To form the second tier of blocks, position a line of smaller cinder blocks on top of the preceding row. Each hole in this block should align with its counterpart from the first tier, meaning that they are above one another and across from one another.
To ensure your cinder block pit is set up correctly, check the alignment and make sure there are no gaps between any of the blocks. The first two rows of cinder blocks will always be mandatory; however, you may add more rows if you so choose.
Consolidate Outer Layer
The cinderblocks will need to be filled in with some dirt, and the soil’s surface should be worked onto it before you prepare your mortar. For this, you’ll need a trowel that is covered completely by fresh cement.
Push the rebar through the blocks so that only four inches of the length protrudes and hammer it if necessary. Fill any remaining spaces with mortar mix, allowing your fire pit to dry overnight.
Consolidate Inner Layer And Finish Up
The next day, cover the inside surface of the fire pit with pea gravel. Fill in around half of some lava rock. Place a layer of cinder blocks over this cemented area and secure them with mortar. After waiting about a day for it to dry, place wire mesh over the top or light a fire grate on top to finish off your project!
