A square fire pit can help you enjoy more outdoor time around your patio or backyard. If you decide to build an outdoor fire pit, you may not want anyone getting too close. We’ve got the perfect solution for creating a safe and secure square cinder block fire pit that is also fun to build. You don’t need any special tools or expensive materials; just use what you have in your garage and start building.
A square cinder block fire pit is a great addition to any backyard and requires no tools, fasteners, or wiring. The cinder blocks are one of the most durable materials to use for this project as they can withstand high heat and weather damage.
A cinder block fire pit is one of the easiest projects you’ll ever do. It’s cheap to build, can be done in an afternoon, and will look great in any backyard or patio. I built this square fire pit myself using basic tools you probably already have in your garage to keep things as simple as possible.
No backyard is complete without a fire pit. If you’re looking for a fun and easy DIY project, look no further than this tutorial on how to build a square cinder block fire pit! You’ll need to find gravel, cinder blocks and sand, as well as gather some basic tools like a level, mortar mix, and trowel. Once you’ve assembled all your materials, dig in! This project will take about four hours from start to finish. Anyone can tackle this project with the right tools – don’t let digging concern you! I built my fire pit in one day with no prior experience.
Compile all the materials you will need.
- Compile all the materials you will need.
- Measure and mark a hole for the fire pit to sit in.
- Cut your cinder blocks to size, making sure they are all even with each other and parallel. (Measure twice, cut once)
- Mix concrete according to package instructions—make sure it has time to dry before pouring into your cinder block base.
Research fire pit regulations in your area.
Before you begin building, make sure that you research the local fire pit regulations in your area. This will help to ensure that your cinder block fire pit meets all of the requirements for safety and legality.
You should also check with your neighbors, as many neighborhoods have rules about what type of outdoor structures are allowed on private property. If possible, it’s always a good idea to get them involved early on so that everyone is aware of what’s going on and has an opportunity to provide input and feedback.
You’ll also want to contact your local fire department, who can provide information regarding things like flammable materials regulations or building codes pertaining specifically to square cinder block fire pits (if any). You’ll want them involved at this stage if there’s anything about which they’re not comfortable with or would prefer being addressed differently through additional precautions or features such as grates under metal bars instead of directly over concrete blocks without having enough clearance between them so someone cannot slip into another person’s space while sitting down next door their own home during cold weather months when they really need warmth from outdoors sources like these because it gets really chilly out here late afternoon before sunset begins happening earlier than usual lately due [reason].
Form a base for your fire pit.
- Put your level on top of the cinder blocks and check that they’re all level. If they’re not, use the metal stakes to hold them in place while you move them into an even plane.
- Use your string line to make sure that each side is square with each other, then check again with the level. This will ensure that when you put your fire pit together, it’s going to stay together!
- Dig a hole for each cinder block using a shovel so that it’s deep enough for the base to sit flat.
Prepare the deck for your fire pit.
- Pick up a sledgehammer.
- Make sure the concrete is dry enough to break easily by tapping on it with the hammer to test its strength, then lift up the sledgehammer and swing it down on top of the concrete with force, breaking through into its softer interior.
- Repeat this process until you’ve made an opening deep enough for your fire pit (at least 3 inches).
Make a square with cinder blocks.
The first thing you want to do is make sure your cinder blocks are level and straight. This can be done by using a level and a straight edge. Using the level, make sure each block is perfectly flat and the same height as all of the others before marking where you want to drill your holes. Mark this area with a pencil, then take out your masonry bit and drill holes in each block where they will fit together when assembled. Drill as many holes as possible on all four sides of each block, making sure that they are centered on that side’s edge this will help when hammering them together later.
If you have more than one person available for this part of construction, consider having one person hold up two blocks while another drills holes into them both (you may need an extra set of hands).
Fill the interior of the square with cinder blocks.
- Once you have all the cinder blocks you need, fill the interior of your square with them.
- This can be a little tricky because it’s hard to tell when a cinder block is level unless you are using a leveler (which I didn’t have). The best way I found to make sure that each block was at the same height was by looking at them from above and seeing if they looked like they were sitting on a flat plane. If one side seems lower than another side, use a rubber mallet or some other heavy object to pound it into place until both sides are even with each other.
- Once all your blocks are in place, remove any excess dirt around them so that it looks nice and clean when we come back later for our next step.
Dig a trench around the fire pit area.
The next step is to dig a trench around the fire pit area. The trench needs to be at least 18 inches deep and 1 foot wide. If you have the tools and time, you can dig it even deeper (up to 3 feet) so that there’s less chance of rain water seeping into your cinder blocks.
The best way to dig such an enormous hole is by hand, using a shovel or pickaxe if you have one available. Backhoes—large machines with large blades on them—are also useful for this task, as are bulldozers if you don’t want to do any work at all.
Lay down gravel in the trench to help prevent weeds from growing.
You can use gravel as a way to prevent weeds from growing around your fire pit. Gravel is easy to lay down and remove—if you want, you can change the shape of your fire pit at any time without worrying about ruining it!
If you plan on using your cinder block fire pit for a long time, then using gravel will be worth it in the long run.
You can build a cinder block fire pit.
If you are looking for an alternative to the traditional fire pit, you can build a cinder block square fire pit in your backyard. This is a fun project that won’t break the bank and will give you plenty of opportunities to get creative.
First, let’s talk about what the cinder block square fire pit is: it’s a simple square structure made from cinder blocks and mortar, with a hole cut into one side where you’ll place your wood or charcoal. The term “cinder block” refers to concrete blocks made out of cement and aggregate; these blocks have been around since Roman times (specifically Pompeii). The term “square” refers to the shape of these structures—they’re all four feet wide by four feet tall by four feet deep (or some other combination). It’s important that whatever materials used are sturdy enough so as not to collapse under extreme heat or pressure from burning materials inside them.
Now onto building this awesome backyard accessory.
Final words
Hopefully, you’re now confident in your ability to build a square fire pit entirely out of cinder blocks. Remember to keep the fire pit small and simple at first so that you can learn the basics without burning down your entire backyard (or worse your house). Good luck, and stay safe.
