I make stuff and have fun doing it. I want to bring my creativity and love for making to you and hopefully give you a great viewing experience.
Komar Project is all about showing you how to make and build things all by yourself. With a little time and lots of hard work you can accomplish anything. The videos you will see on this channel show you my experience in building shop projects, making furniture, and even tool reviews to help you get the job done. Im no expert and I try to make things that I have never done before, and try not to repeat much of it! So, please join us on this awesome Komar experience and see what we can figure out together.
By supporting my partners, you are supporting Komar Project. Go check then out!!!

That's some really black dirt there.
I've always wondered why we keep using steel in rebar. Like I assume it's cost, put its bad for the concrete long-term.
Believing that fiber additive replaces rebar is insanity.
Almost like manufacturer recommendations are there for a reason 🤔
5:09 another thing you can cut with a circular saw: fingers
I hope your video pays for your material costs ! I think saving up for the contractor might be more realistic for me. Or perhaps I can prep my site and prepare my own forms !
You need more friends, took me 7 hours, one day start to finish on a 40x40 slab. Owning a skid steer/backhoe though is kind of a game changer. had 5 friends over, two of which have poured a lot of crete.
More like a project in a repair!
Who'd have thought that you need to mix it first. What a revelation...
I just had a quote today for a 50x60 steel building slab. All in $15-18 per sq foot depending on footing sizes. This did not include sub-grade prep. So $45-50k here in Northern California. Did a 40x60 building 8 years ago (Did forming myself) all in less than $15k including pump truck and finishing crew. Prices were $107 per yard then now $150 or more.
the dry pour is pretty consistent with what I observed happened to a whole bag of concrete that was left out in the rain. It didn't really hold together very well at all.
You really need a mask. Trust me.
Thank you for doing this. First time i heard of dry pour I was stunned that it was recommended to me. sounds easy to do, but imo easy means not great. its like: hey. want some bread? put flour in a bowl, spray some water on it, and stick it in the oven...
Do children have straw in their nest? How does it look now? Any update?
Its almost like an industry that has existed for hundreds of years might have an idea of what they are doing?
In order to produce concrete, limestone CaCO3 passes through ovens in order to eliminate the chemically bound CO2, producing Quicklime CaO. Pouring concrete consists in doing the reversed process by adding water to the lime. For some reason, water only allows to regain the lost CO2 to recreate stone CaCO3 ( CO2 + CaO), i.e. concrete. Uneven, or unsufficient watering explains why this does not work.
Interesting video, but a couple points: 1 If you're bothering with rebar, you need to hold it off the ground. 2 Tyvek, really? The only use for that is if youre putting a vapor barrier on a pre existing structure that didnt have any vapor barrier. Id i were a contractor doing tract homes, i *might* consider it for budget friendly projects. But for my own home? No way.
if you put down 1 inch wet it then at 1 inch wet it, then add the rest of concrete to top. i bet it would be stronger. But never as good as wet pour. Wet pour can be done, in what is called slump. I have saw engineers send a whold truck load of concrete back if it did not pass the 1 inch slump test pouring it into a plastic bucket on the ground.
I only do dry pour for posts other than that it should always be wet pour for slabs. Also I don't think you got it wet enough you really need to soak dry pours.
Why even bother with a dry pour? What motivates such laziness?
The thing with dry pour you have to really soak it ...I mean drown it lol
Excellent comparison 👏 really wanted to know this
You should strip the form and see how long it takes to cure
The chemical reaction of Hydration will not work properly with too much or too little water. "dry pour" is fine for fence posts but i wouldnt do a SOG. It is definitely easier for sure, quick set or not the psi rating will be out if wack at 28days. A compression test will tell for sure
No way
Thank you. You just answered my own question about which method to use for my sidewalk.
where is your mask when cutting that concrete?
Didn't see the rebar when you cut it open
Yeah, for the extra step of mixing concrete, I can’t see why somebody wouldn’t want to do that for the extra benefit of a solid cure
15:19
Now try hot-mixed concrete.
THANK YOU!! IVE BEEN TELLING PEOPLE THIS FOR YEARS....!!!! DRY IS NO WHERE NEAR THE STRENGTH PSI AS A WET POUR!!!
I had a friend enlist a few guys to help him repave his driveway. He saved thousands over hiring a cement contractor.....until after a few years when the concrete started spalling because of improper finishing. Those few guys learned some lessons on how to (not) finish concrete......always good to learn a new skill on 𝙨𝙤𝙢𝙚𝙤𝙣𝙚 𝙚𝙡𝙨𝙚'𝙨 project. L0L.
At 9:15 when you connect 2 pipes using a Y, it looks like your main pipe is perforated. My understanding is that perforated pipes are only used for French drains. Does that mean that you connect your gutter down spout solid pipe to your French drain?
I'm curious that at minute 8:25 you applied a pink product. I'm assuming it was some kind of wood filler, but you didn't comment on that step. Can you share what it was you applied? Did I miss something? I just finished my first window trim on 60 yr old house. I added a step and spread a wood filler on the trim and lightly sanded prior to primer so I wouldn't see the wood grain. Looked silky smooth after painting. Maybe it was what you used at minute 8:25???
I like your willingness to experiment. My daughter’s a lung doctor, “Do you work where there’s any kind of dust produced by power saws or grinders?” is one of her standard questions she asks her patients. It’s a long list.
I've used dry pour a few time and it works well but it was for laying pavers. I find it better than laying them on compacted sand.
It seems that dry pour could still be adequate for some applications, especially if for some reason it's much easier to do. Would it not be suitable for a slab under my propane grill? Seems like its uses may not be many, but it's not use-less. Or did I miss something?
Rule #1 always have mexican do any construction work
I don't know anyone that said it's just as good or better. But for most basic diy stuff it's good enough. Walkways, small sheds, small pads.
Good video. Thanks
Awesome demonstration 👍 thanks
can save some money if you do all the installation work on your own.
It could be that you didn’t water it enough. It’s supposed to be every hour for 8 hours for it to be complete.
Dragged it out way too long. There's a reason why the industry uses wet
Wow…I was building my house foundation as you were step by step , should have watched the video first .
intuitively you can tell that dry packing would not be as strong as properly mixing the concrete. Thanks for confirming my suspicions
I don't see a reason for gravel if in fact it doesn't drain away in somewhat a gravel trench leading away at the lowest point, or else you just made a bowl and filled it with gravel...
Amazing video.. great job
How did u get air out the lines.
