Your descriptions are perfect. You explain the mechanisms behind what is happening, not just how you do it. And that’s the hardest thing to find on UA-cam. Thanks!!!
It really is a worry to see big influencers who know it’s a bad idea, go ahead and make dry pour concrete videos just to get views. Even worse, people who know nothing about concrete watch these dry pour concrete videos then go make dry pour concrete videos of their own. Personally, I unsubscribe from their channel because I might end up learning the wrong advice about something I’m not familiar with. Lucky for me I know a thing or two about concrete, and was able to see that dry pour concrete is actually a stupid idea. However, your explanation was excellent because I was unable to articulate my thoughts about the matter into words. Anyway, glad you got away from that concrete cannon. I would never put my hand up for that job.
As a concrete professional of 25 years I wish I could like this video multiple times. This dry pour fad has to stop. People are left with an inferior, ugly product which won’t perform or last as long as a wet pour. I get it, mixing pouring and finishing concrete is intimidating for a non professional. Also it’s expensive to have someone else do it. But we do it this way because it has been proven to yield the best results, predictably. Like anything in life you get out what you put in. Don’t be lazy.
Years ago, I drove a cement mixer. There's a chemical reaction during mixing that you can actually see, hear, and feel. You can't achieve this if you dry pour. Take this mans advice and DON'T dry pour.
With my background in engineering (not civil engineering) I trust that you know what you're talking about. The attraction to dry pour is for people who don't have 10 years experience pouring concrete timing everything (everything including cleaning tools before the concrete hardens on them), and timing the set to achieve a reasonable finish all without having to buy/store a bunch of large tools in the garage. For my application of several 3x6 ft stepping stones in south central Texas, I do not want a smooth finish like you're talking about. I want a finish that will grip my feet or shoes. If you could address how to get 14 cubic feet of concrete mixed and poured with only a 5-gallon bucket and a garden trowel, I think you would be more effective making your point.
I would rent a concrete mixer from home depot for $35 for the day and mix and pour them all, finishing with a damp sponge float to achieve the texture you are looking for. Quite an easy day of work, and I am pretty confident it could be done faster (and easier) than dry pouring, and the results would be undoubtedly superior with a traditional concrete pour versus the new easy method that people are trying.
I agree that water can and does compromise concrete over time but what stumps me is how do swimming pools last so long while they are constantly submerged in water. I believe that pool plaster is a cement product isn't it? Can you explain this?
I am a swimming pool specialist, so I can tell you that the interior surface of concrete pools is made from dense plaster which is water resistant due to the hard trowel finish and fine mateirals the mix is comprised of. And still that is not waterproof, water does pass through, and over about 10 years time the surface will become rough and porous requiring a new plaster interior surface. The maintenance of the interior surface (also the use of waterproofing systems, ideally) protect the substrate concrete shell from damage from water erosion over time.
Hi I once did a dry poor mixing my concrete rather than the pre mixed bags used in most videos then added water then mixed it with a rake technically a wet poor but without the cost of a cement lorry ,about 3mt by 2mt 5" thick with rebar, it never cracked and had a 450kg milling machine on top ,i,m thinking of doing a 60 mt2 slab the same way as funds are in short supply
You said water going through concrete erode it. Would water going through aircrete erode it as well? I have seen very porous aircrete that water just runs through it like a sieve, any though?
Yes, as water passes through some of the cement component will wash away. It takes, years, even decades, but this is how concrete erodes and the more water it is exposed to the faster the erosion will happen
@@creatingconcrete So aircrete is not as good as everyone thinks it is then right. The bubbles would make it more porous and the lack of sand, there would be no backbone as so to speak to hold it together any water and it would fail fairly quickly yes - no?
No one is claiming that dry poured concrete is AS good or AS strong as wet mix, but maybe it's strong enough for many around-the-home and garden projects. I am not going to last 50 years, I certainly don't care of my concrete does. The professionally poured concrete driveway and sidewalk done 35 years before I bought my house had cracks all over. Also, for people like me who don't have a mixer, wheelbarrow, or other tools and just need a 4 x 6 slab in my inaccessible backyard, it's become difficult to find a contractor (in my area of the Midwest, anyway) willing to even give an estimate, most don't want the job. If they do, it's expensive and will be delivered on their time schedule, whether it's a good time for me to have it done or not. I understand that-- with the investment in their equipment, the big jobs are their livelihood. But that's why dry pour has a place in the world of concrete. YOU would never do it, that's obvious, but it misses the point. Thanks
Yes, as an experienced concrete contractor I would not do it. If you have a small job, then just rent the proper tools for the day from Home Depot and mix whatever you need. For the mixer rental, rental of their van to tow it even plus materials to build the pad would still be under $100 so I do not see value in doing all this work to build something inferior where the actual proper course of action is also easily available.
We all know that "dry pour" would probably hold up for some time with minor, non-load bearing tasks around the house. We also know that no inspector in a civilized country would ever sign-off on "dry pour", which is very telling. I think it comes down to how much pride do you take in your work. As an analogy, if you're repairing a broken wire in the engine compartment of a car, you could use a wirenut and electric tape, or twist the wires together and gob it with RTV. That's the equivalent of "dry pour". Or you could solder the wires together and use heat-shrink for a proper repair, that would be equivalent to premixing. To us that care about workmanship, it's actually very satisfying to know that the work will potentially long outlive us.

Hmmm, don't beat around the bush...is dry pour good or not? haha :)
you place concrete you do not pour it
you pour a glass of water but you place concrete
That may be so, but this method of mixing and placing concrete is commonly referred to as "dry pour" not "dry placed".
