Nice video. Try using a hoe to mix concrete in wheelbarrow and a square shovel to place concrete.

God, that woodlike sound. 🤢 Leave me with my good ol concrete.

Very interesting. Please use a mask / respirator when doing some of these dusty jops. Concrete dust is not good for lungs !

Always wet pour AC slabs and dry pour bridge footings. Always.

Only the uninformed, the easily fooled and those people who can't or won't read instructions would do dry pour cement. Basically fools and lazy people

Your video is appreciated 👍

Cutting fiberglass without a mask? Not good. Not good at all. Yeah, fiberglass rebar is awesome, but please, PLEASE, always wear a mask! Your lungs will thank you for that, because those fibers do a number on your respiratory tract!

Wild that you made two entire slabs without knowing if one would work AND THEN did an experiment to see if it would hold up. Mad man.

I don't think the dry technique would work in a big project like a driveway, patio etc.

It's actually a concrete placement, not a pour..... 🤓...... 🫣

"You won't believe the results!" Really? I knew the results before I saw them.

You proved it; dry pour is weak vs wet pour.

Your test is flawed. The wet pour gets generous amounts of water, while the dry pour is misted? Mist spray the "wet" pour and it will crumble as well. The dry pour can be vastly improved but you will have to change your technique.

I don't understand what you are trying to prove when you know since time immemorial, cements have to be mixed with water all the time.

Dry pour just seems like the lazy people's way to do it

jesus dude, masks are not expensive and you only get one pair of lungs

I call bull on them taking 8 each.

Has anyone done this and can talk about longevity? I'm curious if the bullnose ever comes off or loose from repeated wear and tear. Thanks!

I think concrete pads on AC units are just for vibration ballast. I also think wet pour concrete with concrete designed for wet pouring is obviously going to do better. It probably has to do with dissolving and redistributing chemicals for the curing reaction. my guess is if you made a finer more homogenized mix it might work but the cost to do that is probably not worth the capital investment to make it happen vs all the existing legacy infrastructure.

I will never pour dry, the trade offs are not worth doing dry. You're not gaining time, money on materials or really anything that makes it worth it. I'll only do wet, period!

the chemistry underlying concretes strength needs the water to work. You are not getting the bonds in a dry pour that you do with a wet pour and that should be obvious to any body. Would you mist a dry cake batter in the oven? No, because that'd be stupid.

Don't you need to go down beneath the freezing depth for the base? I think Chicago has winters. I would also like to see how the dry one behaves after a few winters. I would seal it with something like Potassium Silicate (Waterglass)

Great I just dry poured post for my deck. It’s only 2 steps up on a small deck. Hope it holds

Nice acoustic guitar accompanying the video

Hell of a comparison video my man 🤝🏽 I was thinking of dry pouring but I wanted to know the pros and cons. This gave me a great insight on both. Best video I’ve seen on KZfaq

The dry pour doesnt even seem fully cured.

4:50 a nitpick-- the bubbles aren't from poor mixing, rather you mixed plenty of air in.

👍👍👍

That corex is going to collapse over time. Youre better off using thinwall dwv pipe. Unless of course you like digging out and replacing line every few years... Also, if you get any type of heavy rain, it will bounce off that catch basin negating all that work you did. It would be better to use a downspout adapter to take your pipe directly into the ground, where you can put on a 90° adapter and then a cleanout before you start your run. This way you dont splash half the water onto the ground youre trying to keep dry(and away from your foundation as well) Not sure what you were doing with the stone and cloth unless you were doing a French drain, for which i would recommend a thin layer of stone on top of the cloth to help filter out dirt. And yes, i do this for a living.

I e never done a dry pour, honestly didnt even know it was possible lol😅

I have been wondering about the integrity of dry pours! This is a great test, thanks for doing this!

I may have missed it, how long did it cure. Full cure fir testing is usually 28 days. But at least 3 days to start working with.

Looks like dry pour was really pitted out. I also noticed it appeared he overwatered the top at times. That definitely would have weakened the top layer. Nonetheless dry pour doesn’t seem like a good idea for strong concrete since the biggest killer of concrete is weakened mixture by overwatering.

You can get dry pour only fast setting concrete now, it's called fence and post concrete, it's only for fence post and things like that not slabs. It has coarser sand and more cement in it to make it stronger but it's still not as strong as regular concrete.

I wish I had money.

The same… u can spend less money with dry…. Just don’t use your hammer :p easier and fast with the dry..

I don't know where these kids come up with this stuff. Concrete is literally as easy as building a sand castle. What really surprises me is that manufacturers have failed to recognize the obvious new market created by the easy-mode generation, and none of them are working on a dry-pour solution. It may not be as strong, but if they can develop a mix that's even close they would have first crack at sales. The land of opportunity is knocking, and they have their heads in the -sand- concrete. They should ask Sears how that whole ignore internet, keep printing paper catalogs strategy is going for them.

Get a blade guard retard

Online someone said, “The general rule of thumb for [dry pour] concrete drying is 28 days to dry for every 1 inch of slab thickness.” Hence your four inch concrete should be cured for 120 days.

thank you for this test . i didnot believe its smart to do dry pour cement .

Thank you! That's pretty much exactly how I thought it would go in my head.

I use fleximounts less than 200 (always on sale)for a 4x8 they have three mounts per unit. That holds 600 lbs. 5 years later still solid

Great video

I’ve had so many of those pins shear I think they make them to shear off easier so you buy more , like you had with your auger I use for a tiller grade 8 and shear them all the time lol😂 need like a grade 2000 pin

Just a tip for mixing wet concrete. Try using a regular long handle garden hoe. Total life changer after I seen a brickie use one to mix his mortar. Dry pour can work, but it's best for stuff that won't be seen. Though I've seen someone do some basic stuff like this to decent enough results. Much better than what you achieved.

It's the fact that it just kinda splits and falls apart under pressure instead of coming apart with force.

I'd like to see the shaving cream concrete "Air Crete" mix you see on line. then do the testing...

Ironically, the dry pour looks like more work.

I wonder if you were to set up the dry pour with drip for 24 hours of it would cure better. It seems like dry pour requires more work, to be honest. I didn't see that it was actually less work for you. Finish is the same amount of work, and the cutting process is more involved, with having to come back and wet the pad every 45 mins for two days. Seems more labor intensive to me.

wet pour and be done with it, who wants to hang around and blow time misting? plus the finish is way better And I'd wager much stronger without seeing the results yet youll get better results mixing wet pour with a hoe
