- How to build a concrete smokeless fire pit the absolute easiest way possible. No woodworking or concrete skills required. I built the first DIY smokeless fire pit 3 years ago but I want a concrete version for my fire pit patio I'm about to pour. I'm building this fire pit with pink xps foam board to keep it simple so anyone can do it. I love the way this smokeless fire pit turned out and once I stain it and get the fire pit patio poured I'll love it even more! You can stop the smoke and have a fire pit that lasts forever.

That steel fire ring? That is a consumable item in firepits. Might take 2-3 years but you eventually will have a nice rusty ring of burned iron. LOVE the video and this just gave me plenty of concrete ideas for my country home. Thanks.
I LOVE when people don't edit out their mistakes. It gives me more confidence as a DIYer. It's great to know that can be a normal part of the process.
Just showed this video to the wife. She just sighed and walked away. Still, I didn't hear an explicit "no", so looks like I've a project for the summer, boys!
Thanks again, Haxman
😂 Woohoo!
Indifference sounds like a lady yes to me, lol It's not like they don't know how to say no, lol 😆
It's definitely a yes. Also, it's better to ask for forgiveness than permission....
Indifference is how I know my lady is happy. 😆 good luck on the project.
So relatable haha
I worked in construction in the 80s and I recall an on-site engineer that always watched as we poured concrete. I asked him why? He made sure the concrete workers vibrated the mix properly. There's not a lot of strength in bubbles was his reasoning. I've always remembered that.
And at the same time you don’t want to vibrate too much. Separates the aggregate.
@austinatkins408 true speaking, I have seen some bad segregation from over-vibrating the slurry. End up with severe honeycombing on the lower portion of the pour.
You can also use a short piece of rebar to "rod" the concrete mixture and consolidate it to get the air bubbles up to the surface. Similar to "rodding" a test cylinder.
Nowadays we just order it pre-vibrated from the batch plant. Problem solved!
@jaws8817 that's been shown to not be as effective as in situ vibration, bit still better than not
Your wife snorting at your mistake - GOLD! I oft hear that same snort from my wife. It encourages us to do better.
Imagine the real estate agent if you guys ever sold your house. "Sir, why is there 13 smokeless fire pits on the property?"
"i just don't think it was realistic that they could've cremated that many bodies in that much time, ig I'm a skeptic"
Because 14 would be RIDICULOUS!
Find another real estate agent, 13 isn't a logical basis for superstition.
a dog walks into a telegraph office to send a message. the person there asks the dog what they want their message to say. the dog goes "woof woof woof woof woof woof woof woof woof" the person working there says to the dog "that's only 9 words, did you want to include 1 more word? it would be free" the dog replies "no that wouldn't make any sense"
Just turn them into raised garden beds
I like how you do not edit out your mistakes. Humanizes you to the viewer. Great job on the pit!
I appreciate that!
For real. I learn on my own and do my projects on my own. When I see someone successfully completing projects while breaking parts and buying tools which don't get used. I genuinely feel like less of a failure.
The diy smokeless fire pit got me to subscribe 3 years ago. Still watching today. 😂
That's awesome! Thank you! 😁
same for me
Yep....that was the hook 🪝
same for me too! I built that one then, maybe I'll have to build this one too...
Same here
The perfect amount of humor to keep me engaged, the unedited mistakes, the narration explaining the process, and the logic behind decisions made all helped me thoroughly enjoy this video and subscribe for more in the future.
Well said!
I agree! And subscribed
I worked at a rehab facility that thought it would be awesome to take a commercial 6' concrete planter and turn it into a firepit for the residents to have bonfires around during their nightly check-ins. It was pretty awesome for the first few nights, but on the third or fourth night they used it, the damn thing exploded and sent cinders, sharp chunks of concrete, and burning wood flying everywhere. Turns out that, even with proper agitation, concrete is still a very porous substance. Air expands when heated, which could turn your fire pit into a time bomb. This becomes even more likely with repeated heating and cooling. It's why refractories tend to be built with ceramic substrates and not concrete.
I probably wasn't supposed to laugh but the visualizations of the fire pit exploding got me good. Hopefully no one was injured!
@@dustintravis8791 It was pretty hilarious, probably because no one was injured. Just singed clothes and a story to tell.
This one will probably do okay because of the airflow between the metal and concrete keeping the concrete cool.
But yeah, concrete also soaks up water, and when water turns to steam, you get ker-blewy.
The bursting isn't primarily about the bubbles. When concrete hardens, much of the water you mixed it with is chemically bound into the new crystals that are formed. The concrete can be bone dry years later, but that water remains part of it. When it gets very hot, it changes chemically, and the water is freed up. The trouble is, it's inside concrete, so it cant expand, and thus it can get extremely hot without becoming steam. But when the solid matrix cracks, it suddenly releases all that pressure at once and bang.

I was NOT prepared for that part lmao
You sir, are the man! I have been planning to build 3 gas fire pits in my backyard (yep, that is a long story) your instruction, expertise and ahem humor will turn my dream into a reality! Thank you. I have subscribed. Yours is the first you tube thing that I have ever subscribed to, only took me 63 years. (Hope I did it right). Iam a BIG FAN. Most respectfully, mike USN ret.
The all thread not to be confused with the all spark because that makes a transformer come back to life is one of the reasons I watch this channel
What other uses can all thread be used for?
Thank for not editing your mistakes. It’s so much more educating. Great Video; a project I’d like to tackle one day. (Ironically I did edit this comment 😅)
Yeah seriously

That mud mixer looks awesome! They really need to get them in every Home Depot rental location.
I'll just wait for harbor freight (china) to knock one off and make it affordable for a homeowner with projects.
Im 28 and its happening… these are the things i like to watch and do in my free time😭😭
I did a smokeless fire pit conversion to an already existing pit at a house I bought a few years ago. Did almost the same exact thing you did, I just didn’t have to build the walls. Used a galvanized ring, drilled the holes and set it in the middle with a gap for the outer chamber. Then did the capstones using the same technique, just used melamine board for my form instead of foam board. I only made one form and used it for four pours to give me 4 capstones. Used a bit of old motor oil for my release agent, and added coloring to match the existing walls of the pit that had been already done with landscape blocks. Color matching was the toughest part of the project! It turned out great and works awesome. If I had done the whole thing from scratch, I would have just made the whole thing a bit smaller. Having a 3’ diameter inner ring means you need to make big fires (as you mentioned) and it takes a little while to heat up for the smokeless effect to occur. That’s probably why the commercial ones are fairly small as well.
You earned a subscriber, as your rolling storage system has been on my list of stuff as well, just instead of strut channel and trolleys, I had planned to utilize barn door track and rollers instead. Like minds think alike, and I look forward to watching your other builds instead of filming any of my own, lol.
Awesome for hotter climates. I like a firepit for warmth when it's cool and that's always been my issue with the smokeless pits because there's very little radiant heat if you're siting beside it. Cool none the less!
I like how you didn't pretend this went super smoothly and flawlessly. Im more apt to follow and maybe try this with your honesty. Thank you!
I’ve found a better way of vibrating the bubbles out. Attach a piece of pvc pipe on an oscillating tool. Screw it on an old blade. Stick it into the cement and turn the tool on high. Works better than the reciprocating saw.
Rotary hammer drill on hammer mode works great too !
Or better yet just use your wife’s dido 😂

Sonatubes work great too man. Get a 3' and 4' sonatube and cut whatever height you want. We use them all the time on firepits. We actually take fire brick and ratchet strap them to the inside piece and the concrete locks it all in once concrete is poured.
Way more expensive than foam
@jellman101 not if you do a bunch of them and cut them to whatever height you want. We do quite a few custom firepits and as with most companies labor is our biggest expense. You can't really mess up sonatubes they are done, kick it off, strap your fire brick to inside, pour and you're done other than carving or rock work. Every company is different. If you don't have many employees and don't do many of these in a year then you're 100% right
Anyone else blown away that Edddie Vedder is so handy? Haha, that's a compliment. Great entertainment factor and great work!
i've been following you for 3 years. wow! already!
I was here for your first smokeless fire pit and here I am today for your second fire pit
Thanks!
Concrete does not hold up well to high heat. If you don't believe me. Take a torch to it and I hope you have your PPE on. With that said this might work because it doesn't let the concrete to get that hot (unlike standard fire pit). I will stay tuned for the results.
I made a video about this actually on the first pit. The sides are protected by the fire ring. The top doesn’t get hot enough to be affected. As long as you don’t light a fire right after a huge rainfall there are no issues. I deliberately tried to crack the original pit I built with heat and couldn’t do it. You are correct about heat and concrete. If you made a fire directly on concrete that would be a problem.
@@HAXMAN Hey mate, I've seen concrete explode, The fire was actually lit on the slab, it really does go off...!! I'm pretty sure you can get concrete that's better suited to heat...
@@HAXMAN Why not just get castable refractory cement and avoid the problem altogether?
Heat rises
@codycampbell2607 in high-school yeah it does but in the real world it conducts and convects w surfaces.
Quote " Probably one of my favourite tools I've gotten Over the past serval years" Seconds early, haxman wife was helping. Honestly thought he meant his wife. haha She is trooper for being that support hats off!
Love that you don't edit out your mistakes, definitely subscribing. Wife made the mistake of giving me the clear to do whatever I wanted to the backyard...so this is definitely in the cards haha
Awesomeness. I am a former concrete worker, and this is great idea
Not sure if it was mentioned, but rock salt is a great way to add texture. Just sprinkle a little in the form sparingly, and it dissolves later. It can also be added when finishing a sidewalk, just sprinkle some on the concrete before it sets up too hard, and trowel it into the surface. Great video.
It's also absolutely horrible for the durability of the concrete
@@benholler1389 It's only bad for the concrete if you constantly let salt into the the pores through freeze and thaw cycles. So your comment is partially correct. The salt used for this texture technique is rinsed out as soon as the concrete is hard enough to handle a spray nozzle, and is used sparingly for a random texture. My parents have 40 year old walk ways that I helped my dad pour as a little kid, using the rock salt method, that still look like new to this day. Granted, I'm not a fan of textured concrete... I prefer a broom pass so light that you can hardly tell it was done.
I knew it - when you didn’t show the application of your release agent, you forgot it 😂 God bless you and your wife! What a trip. Gonna show this to my husband. We move from the burbs to 3 acres in a few months. Smokeless fire pit is gonna be ideal this holiday season! 😁
Congratulations on the move!
Nice project. I love all the smoke it makes.
Also it was fun to watch you as you virtually have no idea what you are doing.
I had to chuckle. A true DIY’er! Stuff happens, but the goal doesn’t change. I’m sure there will never be those who critique the build, but I’m one to applaud the perseverance. This is a short but sweet vid and I’m going to add this to my list of what I need to do this year. My original fire pit was made from those big box pavers, and while it took a couple hours to build, it looks like…well, let’s just say it looks like a big box build. Many have them. I want different. I need to remember to keep that seed oil handy for my release agent! Very good job.
One of the easiest and stupidly brilliant pseudo concrete vibrators I'd ever seen whipped together was an oscillating cutter with a pipe strapped to it. Sink the pipe with it on, goes in like hot butter. I wish I'd come up with that one! I've also picked up an industrial vibrating head for various projects that can be had for like $35 and use metal worm clamps to put all kinds of things under Serious vibrational power. I have one mounted to a stainless thermos with 1,000 5/8ths ball bearings in it for grinding hard media into powder.
Murphy's Soap in the huge jugs also works great as a release agent for molding, and you can let it dry and build up layers if you want, or just slather it on and pour. Last time I bought it I believe was 2022 and it was $6 at the hardware store.
The only thing I'd address would be drainage, particularly in areas with more clay in the soil than average. You can use PEX tubing and cast them directly into the concrete and run them wherever convenient or pull it after the concrete cures and shrinks off the surface some. It helps a lot with premature rusting of the inner ring so runoff doesn't pool up in the bottom.
I'm definitely going to borrow that all-thread trick next time though. So we're even. 😉
Can you explain a bit more about exactly how you'd attach the pipe to the sawzall to use it as a concrete vibrator? I can't seem to figure out what you mean 😅

I appreciate your SUCCESS/FAILURE, your SORROW/JOY, and that you are showing this along the way to the really sharp projects that you do. It has a better feel than the slick productions that have the viewers feeling unworthy! I am working on my smoosh technique - to be gentle.
I like mixing my cement a bit wet when I pour. It's a lot easier to work the voids out of the concrete when doing something like this. Great video man! Thanks.
I love that you show screw ups and all… all in all quite impressive!!! Stay blessed love the end results !
"Y'all better redneckorize!" I don't watch enough of your videos, but I'm going to fix that, haha. Great video man. Very inspiring.
I love it. Can't believe it's been 3 years already. I've always called those tape measures as sewing tapes', but I think they are actually called "Tailors tape" because if you google search that name a butt-ton of results come up.
Thanks!
Yeah, my mom called them seamstress tapes
Thank you for sharing!
Translation: "whenever" = "when" for 95% of it uses. Thats for us northerners. Thank you for coming to my TED Talk. Love you HAXMAN!
I've never before seen a calculator display fractions, only decimals. Fascinating.
Google "Construction Master". I've had them for over 15 years. Now they have an app too.
Construction master pro. Honestly, if you use it well on a job once, it will have paid for itself. They have an app too.
My son is 59 years old. You remind me of him. I love your sense of humor.😊
Concrete teaches you lessons. Great effort
If you type in your diameter in inches on the construction master calculator and hit the circle button it will give you the circumference as well. Built in short cuts. Invaluable tool that keeps me efficient on the job site. Love your work.
I like how you routinely mix your concrete too dry, despite knowing better.
I too enjoy underfilling my tractor tires, waiting too long to mow the lawn, and under-buying lumber for my next project.
Great build. The end cracked me up with you trying to find a place to store those 'disposable' molds!!! The struggle is real. 😄😄😄
Also...THANKS for leaving the bloopers in...they are what make your channel so relatable. Most you tubers would have easily edited out the bloopers and disguised the real world challenges.
Mighty fine!!! God Bless!!!
This is an awesome upgrade.
Ok, Ill admit it, I laughed out loud with the "then it hit me joke"
7:45 - I call those schneider’s tape (Schneider is Yiddish for tailor, so tailor’s tape if you prefer English)
I figured it had something to do with sewing.
I like this method. Even though it's a lot of work using concrete to make the form, the end result speaks for itself.
Great idea. Looks Awesome!
Yet again haxmeister , fantastic video my wife and I love watching and I think the baby liked it too 😀. Looks like you need a storage shed 😉 new vid!! ❤
Thanks Alex! I need a whole new shop. 😂

I know my 5 little girls would love this. Looks simple enough and my wife will think I am the superman. Nice work man.
Thanks Jacob!
A thing of Beauty !!
amazing work!!!!
Live, learn, and then get duct tape.
After watching this video I will spend $200 and pick up a smokeless fire pit on Amazon. Take it out of the box and done.
Thats why no one will remember your name
And that pretty much sums up the problems in the world today
🤣
The 200 dollar ones on Amazon are like 25 inches. You and a buddy gonna have a blast burning the sticks from the back yard I guess...
@mickym.6711 I cut all my firewood to 20 inches... all the big stuff I burn in an open fire pit.
GREAT video! Thanks for taking the time to provide so much detail.
Thanks Love it, my mental handicap brother loves fire pits, with supervision of course, and I love smokeless wood gasification stuff
PLEASE wear a respirator when you play with concrete!!! Concrete dust is silica...which is glass...which means you're breathing tiny shards of glass. Silicosis is a very real thing!! It's a great project, and you've inspired me to build something similar...but please be safe when dealing with concrete. It will kill you, slowly and painfully!
This is about the dumbest thing I have read. The basic kn95 mask doesn’t protect you from silicosis. Silica itself is used to make glass, concrete and similar products and that’s what you don’t want to breathe in.
@@barretisaacs7718 that's why I said a respirator, not a mask.
I've been mixing mortar for 10 years now. I've been breathing it in nearly every day. I've always wondered if it's damaged my lungs and also if that's why running is so hard to breathe after a while. What do you think?
If the silica doesn't kill you, the poisonous gas from heating the galvanized metal will.
You're using the word "whenever" incorrectly sir. Whenever refers to at least a plural, you keep using it in the singular with specific instances.
Thanks queer
Cool video, thanks for posting

No gloves, masks, or glasses. I love it 🤘
A nice use of a technique used for constructing insulated foundations.

Kids purchased their first homes this year and this would be perfect for our short but sweet Alaskan summers! Now to track down a workable solution for the inner ring, without having to fully fabricate it. Enjoyed the vid HAXMAN! :)
that's admirable
That is sweet! Well done!
There's not a better feeling that you make this and enjoy it! I love that feeling of accomplishment!

Awesome. I’m not great at a lot of things but I may be able to get this done. Can’t wait.
Great job.
Machinist tip. Use WD-40 on your drill bits to make it easier to drill and extend the life of your bits. Especially the step bits. Thanks for the 2 videos. I wanted to build your last pit ,but I like this one better.
Wd is too thin of a lube use a light weight motor oil
Three years ago!? Time flies as a haxmaniac!
Thats awsome... im amazing at showing what not to do... actually its one of my strongest points...
Dude, that was impressive.
One fantastic project. I have seen a video where the man cut a 2 foot 1/2 inch pvc pipe and duct taped to the reciprocated saw and stocked into the concrete form for smother finish. Well done
love your stuff, thank you!
HAXMAN you're a natural!
You got my like and sub as soon as you said you're "showing" us what not to do. Thanks
It’s nice to see that even if you have seemingly no clue what you’re doing, you can still put up a nice fire pit.
Dude is definitely keeping it real. Subscribed.
Okay a couple of comments. I built one just like the video three years ago. It worked exactly as you indicated it would in your video. So very good! Now, the cap plates on ours broke the first time we fired up the pit. This was three days after they were poured. The water still trapped in the hardened, but uncured concrete, caused them to forcefully pop and break. So let that concrete fully cure before applying the heat. Secondly, As I said, it worked exactly as you said it would. What you didn't mention was that it consumes copious amount of fuel. In my estimation 3 to 4 times as much fuel. I had to take it out simply because I could not afford to feed it. It is a proven method for getting a hot fire that consumes its own smoke. The problem is I am not using this fire to forge metal. I'm not even using it for heat. A little fire and some friends; that's all that's needed. So you might mention the fuel consumption issues when you promote these smokeless fire pits.
glad to have found your channel. thanks for the insight, going to do this at my home. !
I saw you were doing it backwards..... glad you caught it before it dried. This is pretty cool. I will probably make one myself. Also, as a math teacher, glad you are using all that math my kids whine they will NEVER use! lol
Thank bro
