Now take two cores each and share the compressive strength results in 28 days.

Cutting corners is always faster. It’s the end result that suffers.

*Structural integrity has left the chat*

For a dry pour, wouldn’t it be an advantage to wet the soil first. So the concrete can pull water from the bottom too. I think I would have also mist sprayed after first bag. Then added second.

My father is a stone mason. Has been for decades. He said the biggest problem is that you now have no way to know if the bottom is getting any water. He said it’s like when you make cake mix. You don’t just keep adding wet ingredients to the top or the top is gonna get soggy and the bottom’s gonna stay dry. You’re likely gonna have a firm top but a crumbly bottom. No one’s saying you should experiment, but there’s a reason cement is thoroughly mixed. If it takes you 19 to fully mix a wet mixture (which is a long damn time in his eyes), imagine what NOT doing that is gonna lead to with your dry mix.

As a man who has been watching youtube shorts for 2 hours while sitting on the toilet, i have no idea what I'm talking about

I've done both. The dry-pour is great for little jobs like pavers, very light duty slabs, etc. However, mixing is the most reliable (and sturdy) because you know it's getting the correct moisture at all levels - especially if the thickness is higher.

I dry poured a 12x12 slab for my little shop, 4 inches thick, was religious about watering and actually kept it wet under plastic for 3 days. Slab has no issues and doesn’t have a crack 3 years later. I used zero reinforcement. Also worth noting, I live in the Deep South. Risk of hard freeze is minimal and I don’t run heavy equipment on it. That said, I have a 125 Gallon Aquaponics system on it and an ATV. It’s holding up perfect

I work in the cement industry in a laboratory. We test the compressive and flexural strengths, as well as the tensile adhesion of our cement products. I've never tested a prism from a 'dry pour' method. I imagine it's terrible but I'd love to try it and get some numbers.

When you mix concrete properly with water it consolidates the mixture to be more dense, and it will definitely be stronger.

I truly don't understand why people resist innovation so much. I'm sure the company tested it a bunch before sending it to the market.

Never did a slab but it sure works on fence posts

“Bite the rebar, I’m going in dry.”

Don't travel down to view the Titanic in this man's submersible.

I just watched this video and don't know nothing about wet concrete but my opinion is that you follow the instructions thoroughly because the manufacturer engineers already did all the years of R & D in the product and after years of development they know what's best👌

I was told from inspector there is nothing wrong with dry pour as long as it’s not structural. If you are doing dry pour saturate the ground first, and go in layers-concrete, spray,concrete, spray etc.. top layer do as this guy did

Wet isn't faster bro, it's the right way that's important

It’s faster in the long run. On a dry pour you’re gonna have to come back to it several times. The traditional way, you lay it and it does all the work for you.

Ive done dry pour multiple times. Just depends on what your doing it for. If its nothing crazy, you got good dirt and its not structural you should be fine.

thanks for showing the result and verifying how the faster method turned out just as sturdy as the mix method. and how you didn't have to spray it multiple times

I wouldn't try dry-pouring a slab, but it works great for setting fence posts where I give zero shits about the resulting PSI strength.

Yeah, the wet mix might have taken you longer to pour, but once poured, leveled and smoothed, you were done. For your work shop, you clearly stated you had to return for several days after to add water to the surface of your slab. That time adds to the job as well. With the mixed concrete, you know that water has evenly saturated the concrete all the way through, once the top hardens on your dry poor, wetting it down a few days after doesn’t guarantee water will make it down to any unsaturated powder below the surface.

You conveniently left the literal hours of hosing down the dry pour that still remains lol😂

With a wet pour its all activated evenly. With a dry pour the top layer activates first and the concrete underneath takes longer. To see which is faster you need to see which is totally solid first! The water doesn't dry out as such, it bonds with the mix!

I think the issue is with how you're measuring the time. You're counting the time you're actively doing something, everyone else is counting the time until you don't have to do anything. The wet pour takes 30 minutes. The dry takes hours.

There is what is called a slump test. It one of the the parameters it tests for is water content in the concrete. It's why concrete isn't poured dry on high rise and is mixed with water. Your dry mix may be faster, but when you add up how many times you have to replace that slab because it broke up, I think mixing with water will win out in the end

I like dry pour concrete because I don't have to mess up any buckets, wagons, totes, containers, etc. It's also quicker. When my sister and I needed to get a mailbox up, dry pour set in 30 minutes after a little portion of water. 🎉

19 minutes, and he was working FAST! Dry concrete in the middle is the problem.

The one you mixed will be dry and solid way before the dry pour. Thats how it is faster

Short answer: No. No it isn't.

The spraying takes at least 1.5 each subsequent spraying because want to soak the top, which has hardened. Said took 10 more sprays=15 min. + the initial 3 = 18. Saved 1 min ONCE at the hose each time, but you arent accounting for 10 MORE DAYS OF IT ON YOUR TO-DO LIST, mindshare, etc. saved a min, extended project time by over a week. So overall, the cost is more.

My dad would mix it as he went, but he would still MIX it

When it comes to concrete, do not cut corners. Do it the right way and it will outlive you

If your way was better or preferred, rest assured that it would have been printed on the bag! If the strength of your concrete surpasses the factory methods, I would be extremely surprised. Faster is not always better!

Man discovers cutting corners saves time

It’s just concrete folks… relax. The man is building a simple platform 💅🏼

Listen, I’ve tried both. And used both for different reasons. One time a client asked for “semi-removable”stepping stones in her pathway. So we did the dry concrete and sprayed water on top. This was strong on the top and sides for the most part, however the center was not as strong as the ones we had premixed. It came up easier than the ones we premixed too. I would assume that the top solidifies and dries before the center/bottom has a chance to get decently wet and stick to the other powder particles

Just so you know, your dry pour is loose and powdery underneath. I do this for a living.😂

I build a fence with dry concrete. Posts are leveled and straight in minutes. Tamped. Build fence in a day. Moisture in ground sets concrete. Done in a day

The only people upset is the people who have been charging people for something that we can be doing ourselves

The dry pour is definitely faster but it unfortunately isn’t as strong and suffers from air holes making parts of the slab weak, this happens as the cement drys and is the reason for the wet mix being the more common method as this minimises it. Like most things in life the easy way usually isn’t the best way.

Don’t know why you got me scrolling down all these comments but the fact you acknowledge each one shows a very respectful, caring and humble person. All the best my man much love

19 minutes start to finish vs 7 hours of coming back and spraying

Please keep doing this because people like you keep me in business lol

My dad built a fence and poured dry concrete in the hole and sprayed it. The fence stayed there until we tore it down almost 20 years later. But when we pulled the posts up, they were separated from the concrete and the bottoms were basically clean. The 2 posts my brother poured where he actually mixed it were stuck solid. The dry method is probably great if you aren't putting any stress on your pads, but I wouldn't trust it to hammer an anvil on man. I hope it works out for you though bro

From my experience with many slabs of concrete the people who are objecting to this dry pour bullcrap are absolutely correct.

The wet pour takes less time cause once you set it it's over, dry pour you have to keep coming back and spraying the concrete ever so often, so your tied to it till finished. That time still counts ! Not just the mixing time .

It's just like leaving the concrete bag outside. When it rains, it gets wet and hardens.

dry pour is good for things like post hole maybe a rarely used slab.. You lose out on degrees of strength in dry vs wet.

Wet is stronger, because the water causes the concrete to become solid. It literally becomes part of the concrete.

It'll never be the same as mixing it. Concrete is supposed to dry from the inside out. Hence the cream on the top. Without that heat it won't be the same... I've done dry pours on posts and when you pull them out they aren't even half as strong as if you did it correctly and you did it to a 4" slab. No bueno. Not at my house that I plan on having last my whole life.

You said in the original video that you sprayed it 10 times. Make sure you add that time into the equation. Then test the samples and see which slab is stronger, higher quality concrete. Factor that in as well.

This ladies and gentlemen is a case study for the dunning kruger effect😂💀💀

I am a concrete man. The only thing I dry pour is fence post footings. I still add the amount of water it tells you on the bag. Then rod it. Wet pour with rebar is the best.

If you do something, doesn't matter what it is. Do it right, the first time so you won't have to come back and do it a 2nd.

I lay carpet and tiles down before the framing goes up. Saves cutting around things.

Contractors hate these videos.

Mixer is 75 dollars at harbor freight. Mixes two bags in 2 minutes or less. Pour and done

Large and small aggregate and sand should be completely covered with the portland cement paste to form a continuous matrix. Wet mixing is the best way of assuring this. BTW, concrete needs at least 21 to 28 day moist cure to reach optimal strength. Don't let it dry. Once set, keep it moist as long as you can.

I think the water will not pinitrat down far enough. So, the concrete slab will only be the very top layer. You can flip them over to check this out. The one you mixed the water will be solid.

I've never done concrete but I'm thinking the dry. If you're using the mist setting which won't disturb how perfectly flat it is. The mist is not going to get several inches deep into that concrete to fully cure all that stuff into. Basically rock. It's going to have the top solidify on top of a bunch of powder is what I'm thinking the complaint is

Concrete laborers pockets becoming lighter 😆

You forgot the multiple hours after the fact you having to keep wetting it all day 😂

It's common sense A proper wet mix is always going to be the best You know it I'm your heart❤

Comparing the dry pour to the wet pour. Wet pour will last longer

I saw the pressure test on both of them and, wet is definitely better than dry. I thought about doing a dry pour but why not have the real strength of wet concrete.

Im a building and welding inspector. Ive tested, casted and broken tens of thousands of concrete cores (cylinders). The dry way if perfectly fine for the applications here. Quick crete is literally designed to hydrate throughout with minimal mixing and minimal hydration. Because its mostly concrete fines and not much if any super hydrators (fly ash, porous aggregates, coarse sands, etc.) Thats why post hole concrete works. "Add post. Add dry bag. Add water. And enjoy". Its cement hydration ratio is so low because its not meant to hold up a tower, for yard slabs its totally acceptable. Hence why there are no building codes for it as long as its a non structural or non post tensioned slab or load bearing. Using add mixtures such as plastacizer, water reducer, transmission fluid (air). Has little to no effect because the average batching for concrete, is meant for large, structural and load bearing pours. Thats why they use concrete trucks and pumps or conveyers, not 20 guys carrying 50lb bags of quickcrete. Cmon now guys, common sense here lol

What was the compressive strength from a cube test, and cost per m3? I imagine that the conventional wet mix with appropriate aggregate and vibration would win.

It's not based on speed, it's based on quality of the finished product

I think the dry one might be faster but weaker while the wet one takes longer, but he’s stronger

Been pouring concrete for over 40 years. Now I find out I've been doing it wrong the whole time. These do it yourself homeowners are really smart.

Concrete pad on wood mulch, thanks for testing that so I don't have to.

CONCRETE SETS UP 80% HARDER IF IT'S KEPT WET FOR DAYS. BOTTOM SIDES TOP SEALED. IT SETS BECAUSE OF A REACTION WHILE WET, NOT DRYING OUT. IT WILL SET UNDER WATER.

I built some ghetto retaining walls in the same spirit. Take entire bags of concrete and stack them up. Water them down and let rain do the rest. In a few weeks with nearly zero effort and no tools, you've got a workable structure. Probably not the best strength and certainly not professional. But it is simple and I don't care what the neighbors think. Good at ya! Work with what you have.

There's a lot of reasons why they make concrete the way they do. Hope you win the prize someday.

The speed issue is in how long till it is usable IMO. The wet pour will have most of its strength by day 7. The dry pour will probably take nearly a month and probably won't get as strong permanently. I have never seen test data for it though. The quality will be hard to control too as you don't know how wet the inside gets. That makes testing it difficult

I have tried telling people that dry poor is better and gives a stronger concrete but they think they know better and they don’t know crap

The dry pour might be initially quicker but don't forget to add the time it takes to go back and re wet it.

You should be soaking the ground first. It will draw much of the needed moisture from the surrounding soil. This method works especially well in areas that get frequent rainfall. If you’re in an arid area, I would recommend a wet pour. Also, this is for a slab that won’t have heavy objects in it… like a picnic area or possibly a shed.

We have always done the dry concrete for years. Never had a problem. Dogs didn't care. Cats didn't care. Cows didn't care nor did the hens or ducks.

Im pretty sure rain over the next few months is gonna make the dry pour strong ASF

Dang, you should start a concrete company pouring powder foundations. Hacked the whole system lol

❤ the MODEL A in the back ground.

I'm sure the standard pour had a better result than the dry pour

I prefer the efficient way not the lazy way

That's how they built the Hoover dam. Saved time, lots of cash

It depends on what you need the slab for. If this is for a path, or to hold a landscaping feature it should work fine, but if you are consistently moving anything over a few hundred lbs on it the dry pour is going to crack way sooner than the wet mix.

As a person who lives in a Super humid climate, I have seen many a solid bag of Quickset. They seem prone to breaking,but that might be the rounded shape doesn't support itself. Interested to see your testing rubric and results.

PSA: Please wear gloves when messing with concrete so you dont get burns (High pH), poisoned (Too much absorbed into blood through skin and inhalation), or have an allergic reaction.

You are so right! Saving time is way more important then quality! 👌🏻🤦🏻‍♂️

Bet if you knock it open you'll find powdered cement. Might set completely in a year depending on how much rain you get. Would you suppose that would cause an irregular lift at the bottom core?

It's your place , as long as it worked and your happy

Bro been doing concrete 22 yrs..no way it's as strong...

We can save 99% of the water this way but we have to leave these boards on the entire time.

You forgot the part where it takes hours because you have to keep going back out every half hour to re-wet it. With the wet pour, it takes twenty minutes and the job is done. You can go shopping for some flannel jackets, new boots, a new shotgun, take your ol lady to a movie, go fishing with the fellas, go hunting with the kids. Hell my point is you don't have to sit there all day going back and forth every half hour to re-wet it. I live by a simple ol school motto "if it's not broke then don't fix it".

As soon as he starting using his bare hands I knew he didn't have a clue what he was talking about

Dry set/pour works better when working on pitched areas, other than that, and fence post holes, it mainly just provides a lot more work time, and the ability to make a flat surface on a pitch.

Dry pour is not as strong same as if it’s too wet once wet then dries there will be tiny air voids if it’s mixed wet but not too wet when it dries there is no tiny bubble voids. Try it and cut it with a diamond saw and see the internal structure but look close they will look the same from a distance

All I know is that when I stored 8 bags of concrete for 6 months, in the original paper bags in my completely dry shipping container, it turned into completely solid concrete that I had to bust up with a sledge hammer. It was completely 100% hard as a rock!
