How To Build A Square Fire Pit With Concrete Blocks

A fire pit is a great way to enjoy your backyard with friends and family. we show you how to build a square concrete block fire pit. We used 95 lbs of cement blocks and 390 lbs of sand to create this concrete block and mortar fire pit with an exposed stone design that is perfect for smaller spaces. Constructing a square fire pit has numerous benefits over circular or round designs because it consumes less space and creates more seating.

Concrete Fire Pit Block is a square or rectangular shaped fire pit that works well with the same concept of building a round or circular one, but in this case, it is made up of concrete blocks. It also features a metal grate for you to use when putting wood on it so that it will not fall or burn up easily. What you’ll need: Square fire pit, rebar, liquid concrete retainer, tape measure, leveler, shovel and the following materials: 16″ concrete blocks or bricks.

We love spending time in our backyard, but it felt a bit incomplete for us. There was one area where nothing but weeds grew no matter how hard we tried to change that. So we decided to build a fire pit there and make the space usable, inviting, and fun for our family in the process. The great thing about using concrete blocks is that they’re inexpensive and easy to use even if you’ve never worked with concrete before. In fact, since they are so easy to work with, it’s a wonderful project for even beginners DIYers. If you’re worried about making mistakes or not being able to complete your project, fear not. We’ll walk you through every step of this simple project so that you can enjoy your own fire pit in no time at all.

Excavate a square hole, about six to eight inches deep.

It’s time to excavate a square hole, about six to eight inches deep. This depends on how big a fire you want to have and how many people are sitting around it. You don’t want the fire pit to be any deeper than that, as it could put out your flame or cause smoke inhalation.

To make sure you’ve dug the right size hole, use a measuring tape and measure out two feet in every direction from where you’ll be placing your concrete blocks (so four total measurements). Use these measurements as guides when digging so that your final pit is just right.

Lay a perimeter of about two courses of concrete blocks around the hole — half-length pieces on the outer edge.

Lay a perimeter of about two courses of concrete blocks around the hole — half-length pieces on the outer edge. (The size of your fire pit will determine how many courses you need.) The blocks should be placed with their flat side facing out, with a 2-inch gap between them.

Lay the next course of blocks by cutting a whole block in quarters, to change direction.

Lay the next course of blocks by cutting a whole block in quarters, to change direction. The blocks are laid on the ground until you reach the height you want for your fire pit.

To lay these blocks, cut each one into four pieces: two short sides and two long sides.

Once you have created a circular base, break up each whole block into quarters and use these pieces as spacers.

  • Fill in any gaps with smaller pieces if needed.

As you work your way up, keep creating a circular shape until you have reached the top.

As you work your way up, keep creating a circular shape until you have reached the top. For example, if you are building your fire pit with four concrete blocks, then once you have created the first block and built it to the height that is comfortable for sitting on or around, start connecting another one vertically off of this one. Repeat this process until you reach the top of the fire pit wall.

When connecting each new piece of concrete block to an existing one, make sure that there is enough space between them so that when they dry out and harden completely (which can take as long as two days), they will stay together without crumbling or falling apart. To do this, place a small amount of mortar in between each connection point before affixing them together using screws or bolts at each corner point where two pieces meet.

Once all layers are connected together and filled in with mortar wherever needed for structural integrity, allow everything to dry completely which may take anywhere from 16 hours to 48 hours depending on how much water was used during mixing.

Remove the spacers, fill in any gaps with smaller pieces if needed, and you’re done.

Now that you have your square fire pit ready to go, you’re probably wondering how to use it. The best thing about these fire pits is that they’re so simple and easy to build! Once you’ve laid out all of the blocks and secured them with concrete, there really isn’t much else for you to do except enjoy its warm glow at night.

Because these are made from concrete blocks instead of stone or brick, there’s no need for mortar between each block. This means that even if a piece breaks off over time (which rarely happens), it won’t damage any other pieces as long as they aren’t too close together in the first place.

If there are some gaps between certain stones around the edge of your square fire pit or if some smaller pebbles have fallen out during construction—which can happen if one side of a block has been cut slightly differently than another—feel free just fill them back in with smaller stones or pieces until everything looks nice again.

Creating a fire pit can be easy with concrete blocks.

Creating a fire pit can be easy with concrete blocks. Concrete blocks are durable, affordable, and versatile. They can be used in many applications including building a raised bed or creating a beautiful outdoor fire pit.

There are many benefits to using concrete blocks instead of traditional brick or stone materials for your outdoor projects:

  • Concrete is easy to work with because it’s lightweight and doesn’t require heavy machinery like bricks do. You can easily lift the block by hand and move it where you want it without any extra help from tools unless you need to cut through multiple layers of concrete at once (more on that later).
  • Concrete is durable because it’s made from cement mixed with water-resistant additives such as sand or gravel which makes them less likely to crack than other materials when exposed extremely cold temperatures during winter months such as snowfall or frostbite from being left out overnight before use during summer months where heat waves causes condensation inside storage containers containing food items stored within them causing mold growth around containers’ rims resulting in health hazards associated with eating those foods contaminated with mold spores; especially if those foods have been sitting inside those containers too long without refrigeration during hot weather periods (which should always be avoided due their effects on human body).

Final words

If you want to build a fire pit, concrete blocks are the perfect material for the job. They’re easy to work with and can be found at most home improvement stores. Plus, this project doesn’t require any special tools or skills: just follow these simple steps and you’ll be able to create an attractive DIY feature that will enhance your outdoor space.
