I love all of these very positive comments. It's interesting to see the clash of high tech equipment and a guy in a bowling shirt and flip-flops running the riding trowel machine with a laser level.
This video is sadly propaganda. No company in China would spend money on this equipment. Construction companies in China are incentivized to spend as little as possible when building anything. That's why all their builds collapse after a few years or just never even have anyone occupy it. Just a good way to build a lot and artificially boost a countries GDP.
Like you, I’ve done quite a bit of work with “concrete” floors - both finishing off floors that others have laid (badly) and to our barn conversion. I’ve seen and used the rotary trowel machines but never seen the ride on version but I can see it’s just sensible for those large areas. For the barn conversion, we were thinking of having a concrete floor with inclusions; almost like a terrazzo style but it worked out cheaper to have a normal substrate and large tiles on top. For that job, we had an area 30m x 12m x 0.3m and it took many loads from the concrete mixer lorry. We were told that steel fibre is okay but the best reinforcement was a plastic. These were helical shapes perhaps 5cm long made out of recycled material. The idea, we were told, was that the helical shape provided a much better bond than just straight fibres of anything. Is that right? Who knows? It’s been down 5 years and, in the portion not yet tiled, the cracks are extremely small. In terms of the quality of work shown, it is extremely high. However, it is obviously being used as a showcase for this company’s work and therefore, it wasn’t a case of cost-effectiveness but rather just get the best possible result regardless of cost.
@@theofarmmanager267 I guess putting so much effort in only makes sense for very defined application like special laboratories where they have to minimize any toleranze, or high precision machine work, where the ground and machine also have to be as level as possible. But it's still quite impressive how far we come from just pouring concrete in.
Problem is its like glass so bloody slippy for fork trucks and loaders. they tried it in a local potatoe shed and had to rough it up after the first year
@@TheRealHusk nice try but actually at the very end of the video, when there is absolutely zero water in the floor, it reflects pretty well. But you probably didn’t watch you sour dusty guy
@@borbebular9482 There absolutely is water at the end look closely you can see one of the pillars on the left side has a dry splotch of concrete next to it
I helped a friend install comslab which are long span metal forms to lay your concrete floor on second levels and above on a new hotel going up in Detroit, It was pretty cool to watch the final outcome. At least these guys have a floor already to walk on, we had to build the floor by walking on beams.

It's quite common for quick welds that the welder just looks away with eyes closed. Not that it's a good idea due to sunburn. Any unprotected skin gets sunburned if you weld like that for a whole day.
i worked in a modern research facility and some of the halls were just epoxy painted concrete and if you shuffled your feet along you could feel and see the humps and lumps in the floor
@@geoken2 honestly uneven floors are hard that’s why there’s a sub trade within it that come in and lay self leveling on high rise/condos . To make life easier for hardwood guys . Now tilt ups l/commercial are a lot easier to level as it’s poured in panels so it’s less stressful for guys
@@merlinious01 Concrete pairs well with steel, as it undergoes a reaction with it. The steel will form a thin film similar to how aluminum will oxidize. Also, have you ever tried working with glass fibers? Horrendous. The steel is less rigid (more ductile) than the glass, and will not break from compression or shear stresses, while the glass probably would. Another reason that steel is paired with concrete is that at any normal temperature, the thermal expansion of the two products is so similar that they remain bonded. Would probably not matter on the scale of the fibers, as they are only an inch or two long. We do use fiberglass reinforced fibers though. It is very common around here, and it reduces cracking. Typically we only use steel fibers on high wear concrete, like the lining of machinery where it is subject to high speed dust, or on shop floors where mining equipment is worked on. Also some bridges.
@@hosmerhomeboy Thank you for the explanation, and it makes sense. I hadn't considered thermal expansion coefficients, nor the ductility. I used to work in the plastics industry, specifically making injection molds. It is not uncommon for plastic parts to be reinforced (impregnated) with either glass fiber or glass beads. Beads for shock absorption, fibers for stiffness. Both are more expensive because the glass wears out the mold far faster as it works as an abrasive. I had a feeling that I had heard that glass fiber was used in concrete sometimes, so didn't think the question would be too stupid.
@@thezoomguys385 Pardon my ignorance, but why would it be significantly better indoors? Isn't the air basically the same in terms of oxygen concentration? The concrete I've seen seems pretty porous, as if it can allow some water to enter. If moisture can seep in, couldn't the air?
I love the difference in welding posture that you can observe between Chinese welders and North American welders. Chinese welders in the field have that classic deep squat with flat foot and North American welders hunch over with asscrack exposed. Similarities can be seen too, like: Guy holding the work who doesnt really want to be there and safety squints.
I found it interesting they laid plastic down. We have found it problematic having the plastic as it seems to cause issues with the drying process. We see a lot of surface cracking all over. You can see this cracking at 3:46
Waterproofing? I'm not sure where this is geographically, but where I live the water table is only a couple of feet down and water comes up through the concrete in the houses. We had carpet in one room without a water barrier under it and when I put one of those plastic chair mats down, so I could roll an office chair on the carpet, it got very wet and moldy underneath very quick from the water coming up through the concrete foundation.
The plastic vapor barrier in that scenario would be a pain making the concrete difficult to work. An accelerator. then topping off with that powdered topping. This all looks like a headache. Water not being able to go down because of the plastic. But wanting to walk on right away to power trowel. It looks like it was beginning to set up when they were top coating it. But cold joints would be a big pain for having to get so close to top coat
This music sounds like they are overcoming adversity and doing something truly heroic. Is this the same soundtrack they use when they go check the mail too?
He ain’t the only one. Had a laser screed do a job in 1999 that had a very experienced crew. Lots of 10 year Muckers and 20 year supervisors. Curb and gutter crews would show up at 7 order 20 yards at 10 and another at 2. All without a single form set. We had 3/16” birdbaths at worst. We had a million dollar saw on one end of the slab and truss fabrication tables on the other end.
I have done a lot of that professionally, I grew up in the trade. The rick sanchez perfect level bit is one of my favorite pieces of comedy EVER. Cracks me up every time.
Can we take 1 second to talk about the dudes pants @2:29? What the hell happened? This is a baller precision master piece.... and on the day they're filming, he shows up with the most a hybrid of jeans/cut offs!?!
Having worked in construction, what are you gonna do when faced with that guy? You NEED him. Muds settting. NOW. he can wear what he wants. Also, dress acumen does not correlate with workmanship. perception of workmanship, yes. But I'd almost argue that the best and fastest crews I've seen are a bit worse for wear. Concrete destroys your clothing, and working it is demanding, and HOT. So you wear junk, and it gets wrecked. An extra hole keeps you a bit cooler. Ofc, on industrial sites with codes for that, they pay through the ass to buy everyone new clothes constantly.
Yeah TBH the amount of people and variety of tools and equipment screams "we don't really know how to do this so we'll try just about everything in the DIY store's catalogue".
@@TheNefastor doesnt it also scream "we have a flourishing economy and endless orders for huge warehouses/factories, so its totally worth it to invest on good equipment for all facets of the job." ?
@@Mr30friends dude, it's a hangar. All countries in the world have them, even the most backwater third world countries. What are you putting in yours ? The country of Taiwan fills theirs with world-leading microchip manufacturing lines no one in China comes close to matching.

Also, you really need to understand that your "flourishing industry" impresses no one. When you built that olympic ski jump ramp in an industrial wasteland, you may have thought it made China look advanced, but everyone around the world wondered why you did something so weird, ugly and frankly stupid. You're still acting as if the industrial revolution was yesterday. Maybe for you it was. Everywhere else, it's mundane. You really need to wake up.
Now add a bunch of plumbing and electrical protrusions, and a bunch of rows of anchor bolts and hold downs and structural steel blockouts, and see how all that new tech works out.
No in-slab reinforcing and no indication of fiber in the mix. They cut the joints way too deep and too far apart. Might be a flat floor - can't wait for the curling to start with all that plastic directly under the slab.
curl up at the edges, then crack at the low point when the edge comes back down. Gonna be not a lot of fun for someone. But hey, they had 40 or so people with shiny hats and clip boards, there must be quality, right?
What BS, it's clearly shown to be reinforced with steel fiber. It's not because we buy the cheapest stuff from china that they are inept at everything, they are perfectly capable of good concrete work.
No rebar or welded wire? If anything, rebar and welded wire is more important than metal fibers considering the fibers won't hold it together as much as rebar and the wire. If you do the rebar, wire, and the fibers, then it will be really strong (still depending on your drymix/portland ratio of course.)
Pretty sure they knew what they were doing did you see the amount of engineers and people planning out you think they would skip on something like that if it was important
@@dmeyer6994 they were showing off their equipment. that's what they were doing. If there were rebar, the equipment would have ruined it and we would not have this nice ad to watch. Engineers/ shiny hats standing around has little bearing on the workmanship. I very much doubt those were engineers, as almost any structural would not have signed off on building even a garage slab with no reinforcement. What they did was create a super smooth, hard slab that is neither superflat, nor strong. It will certainly crack and come apart unless the sub base is some sort of perfection. I will say the finishers looked to be fairly skilled with their tools, but you don't create a super flat slab by setting your screed with a string. It is done with massive machines using a laser to guide them, and NO ONE walks upon it after the machines have passed. This was a sales video. Most real projects would have conduit, thickenings, elevation changes, anchor bolts, and drains to get in the way of the machines, thus making them look ponderous and inefficient for large portions of the slab.
@@dmeyer6994 I mean it’s good for “flexibility strength” but I’ll then ask you this. Does concrete flex? Not as much considering it’s a solid object that is made up of lots of smaller pieces that’s just held together by a bonding agent. That’s why rebar is the best considering it holds the whole thing together with larger pieces of metal that doesn’t flex as much as little fibers that aren’t connected to each other.
I would look at the overlap between fibers, if there is enough in there that each fiber is adhered to two or three others, the net effect could give it adequate tensile strength. What type of steel was not mentioned, but some variety of stainless I'd guess, budget was no object on this project obviously. As to flexing in concrete, it does not flex. It breaks, the addition of rebar or steel mesh increases the force that must be applied to cause it to break.
Don't not why they don't float straight after they level to avoid walking back over and filling boot holes again, seems to void the work of the levelling machine.
Actually the leveling machine has two jobs. One is to level, but to also push the drymix down to form a stronger bond and allowing the top to become smooth in the process.
@@jordankapeliela yeah whatever,we use a levelling machine and never walk back over creating more work, good for you.,we got quad ride on's, these guy's only have treble's, amateurs
It'll fuck up sooner than that. no rebar, so unless the sub base is some sort of perfect material, and the floor is never subjected to any large loads, it's gonna fuck right up.
With 30 years in the industry, I'm sorry to say there is still multiple errors here. Structural steel is paramount. Regardless of how many fibres you put in, there is nothing stopping it from cracking and coming loose over time. Too much emphasis and relying on machines, particularly placing. If your guys cannot pull a screed, forget it. Here in Australia, we operate on a + or - 3mm tolerance envelope. Over 25 sq mtrs. So you can get your screeding flat accordingly. And once you start machining your slab, stay off the bloody thing, your putting holes everywhere and it's way more work to fill them up. And if that was what I would assume a Master Plate powder or iron filings being layed on top, you need to compact that in with an old school Kelly float, one big 15mm steel plate , then your pan, then your combination blades, then finishing blades. Those ride ons are fun btw, Razorback produce the best concrete finishing machines....imo. Absolutely no shade tho, just something to consider.
surprised no one else noticed the lack of rebar, or the thin floor. Must be a show room or something, because if it is a shop floor around here, it is typically a lot thicker, with multiple layers of bar, and thickenings/ pads cast in where machinery is to be placed. I mean, if you're going to operate equipment on it, 8" with 15mm rebar is a lot more normal. Last crane shop I built had 16 inches of concrete with a double mat of 15mm on 1' centers, plus a third mat in some areas. Tirepads for haul trucks run up to 3 feet thick with 2- 4 matts in them of 25- 35 mm rebar. But that's the extreme. Usually a garage would be 4-6 inches thick with 10-15 mm on a 2' spacing or less. I've found the 10 mm on a 2' spacing will crack and fail a lot of the time, depending on the sub grade. But I'm just a concrete repairman/ finisher / cribber / demolisher. What do I know?
I must have a knowledge deficit. Is the floor “flat” as in level or simply smooth and shiny? I don’t see some sort of leveling that extends between the machines doing the laying and smoothing. Something along the lines of a laser keeping the machines at a constant height. Floors look wonderful, but the last time I saw such an effort, it was to keep the floors smooth and perfectly level, such that a 5 story fork lift could feed racks without danger of falling over.
Some hard hat wearing people were also riding the trowel machines, so.....and how do you know who's more senior at the job? Or maybe you saw what you wanted to see?
@@TAllyn-qr3io Lol, so when you're caught saying things about a video you had obviously skipped through, your defense mechanism involved (A) pretending you didn't mean it, and (B) pivoting from the embarrassment that was yours alone to a nebulous discussion of PC. Impressive, if only you'll learn how to use parentheses, that would be peachy.
The builders want to show the quality and professionalism of the construction. details make a difference! Judging from the dress of the staff and the quality of the staff, whoever believes is unlucky
I'm a lime putty plasterer and I would love to have a motorised float, they look like a lot of fun but totally impractical for me to have because I rarely do floor screeding and ceiling work. What's the cost of one please GWB?
I work for a company that does that kind of work and man making them floors look like that takes a long time. Usually we start at 2 in the morning and them guys in those riding machines are on them till 5 in the afternoon. Specialy in the cold. I'm on the pour crew so we use the screed which is a cool machine but man this kind of work sucks.

curl up at the edges, then crack at the low point when the edge comes back down. Gonna be not a lot of fun for someone. But hey, they had 40 or so people with shiny hats and clip boards, there must be quality, right?
What BS, it's clearly shown to be reinforced with steel fiber. It's not because we buy the cheapest stuff from china that they are inept at everything, they are perfectly capable of good concrete work.
All I can see is Morty stepping off that and saying "Reality is a lie!"
No rebar or welded wire? If anything, rebar and welded wire is more important than metal fibers considering the fibers won't hold it together as much as rebar and the wire. If you do the rebar, wire, and the fibers, then it will be really strong (still depending on your drymix/portland ratio of course.)
Pretty sure they knew what they were doing did you see the amount of engineers and people planning out you think they would skip on something like that if it was important
@@dmeyer6994 they were showing off their equipment. that's what they were doing. If there were rebar, the equipment would have ruined it and we would not have this nice ad to watch. Engineers/ shiny hats standing around has little bearing on the workmanship. I very much doubt those were engineers, as almost any structural would not have signed off on building even a garage slab with no reinforcement.
What they did was create a super smooth, hard slab that is neither superflat, nor strong. It will certainly crack and come apart unless the sub base is some sort of perfection.
I will say the finishers looked to be fairly skilled with their tools, but you don't create a super flat slab by setting your screed with a string. It is done with massive machines using a laser to guide them, and NO ONE walks upon it after the machines have passed.
This was a sales video. Most real projects would have conduit, thickenings, elevation changes, anchor bolts, and drains to get in the way of the machines, thus making them look ponderous and inefficient for large portions of the slab.
@@dmeyer6994 I mean it’s good for “flexibility strength” but I’ll then ask you this. Does concrete flex? Not as much considering it’s a solid object that is made up of lots of smaller pieces that’s just held together by a bonding agent. That’s why rebar is the best considering it holds the whole thing together with larger pieces of metal that doesn’t flex as much as little fibers that aren’t connected to each other.
I would look at the overlap between fibers, if there is enough in there that each fiber is adhered to two or three others, the net effect could give it adequate tensile strength. What type of steel was not mentioned, but some variety of stainless I'd guess, budget was no object on this project obviously.
As to flexing in concrete, it does not flex. It breaks, the addition of rebar or steel mesh increases the force that must be applied to cause it to break.
Don't not why they don't float straight after they level to avoid walking back over and filling boot holes again, seems to void the work of the levelling machine.
Actually the leveling machine has two jobs. One is to level, but to also push the drymix down to form a stronger bond and allowing the top to become smooth in the process.
@@jordankapeliela yeah whatever,we use a levelling machine and never walk back over creating more work, good for you.,we got quad ride on's, these guy's only have treble's, amateurs
the light shining across the floor tells it all. they all look flat until you hit them with low angle light
The Italians have been doing this work since the time of Rome.
is this the same kind of flat when morty experienced perfect level?
Was going to say that if I ever step on this floor, my mind would probably need to be blown.
Only to have that warehouse sit unused for years before deciding to tear it down.
It'll fuck up sooner than that. no rebar, so unless the sub base is some sort of perfect material, and the floor is never subjected to any large loads, it's gonna fuck right up.
@@hosmerhomeboy it has steel fiber in the mix. No rebar needed.
@@chrisestill8825 someone who paid attention. 👍
Wounderful job
I’m sure they pilfered this technology. Probably from the US.
Very very nice.
I am proud of you.
I dabble in precision, Morty...
And then a cat walks across it when your not looking
But the cat would know when to use _you're_ instead of "your".
How I feel when I put my hair clippers on the shortest setting.
With 30 years in the industry, I'm sorry to say there is still multiple errors here.
Structural steel is paramount. Regardless of how many fibres you put in, there is nothing stopping it from cracking and coming loose over time.
Too much emphasis and relying on machines, particularly placing. If your guys cannot pull a screed, forget it.
Here in Australia, we operate on a + or - 3mm tolerance envelope. Over 25 sq mtrs. So you can get your screeding flat accordingly.
And once you start machining your slab, stay off the bloody thing, your putting holes everywhere and it's way more work to fill them up.
And if that was what I would assume a Master Plate powder or iron filings being layed on top, you need to compact that in with an old school Kelly float, one big 15mm steel plate , then your pan, then your combination blades, then finishing blades.
Those ride ons are fun btw, Razorback produce the best concrete finishing machines....imo.
Absolutely no shade tho, just something to consider.
3mm over 25sqmtrs , wow.... This is amazing
@@phantomz1617 I'm so sorry, I forgot to add + or - 3mm..sorry my mistake.
surprised no one else noticed the lack of rebar, or the thin floor. Must be a show room or something, because if it is a shop floor around here, it is typically a lot thicker, with multiple layers of bar, and thickenings/ pads cast in where machinery is to be placed.
I mean, if you're going to operate equipment on it, 8" with 15mm rebar is a lot more normal. Last crane shop I built had 16 inches of concrete with a double mat of 15mm on 1' centers, plus a third mat in some areas. Tirepads for haul trucks run up to 3 feet thick with 2- 4 matts in them of 25- 35 mm rebar. But that's the extreme.
Usually a garage would be 4-6 inches thick with 10-15 mm on a 2' spacing or less. I've found the 10 mm on a 2' spacing will crack and fail a lot of the time, depending on the sub grade.
But I'm just a concrete repairman/ finisher / cribber / demolisher. What do I know?
@@Harold_Flite + or - 3 mm is still pretty good. I'm hard pressed to do any better than that.
@Yuck Foutube nice
'
love that flat smooooth cement / concrete...
but when get fully completey dry then later will be crack apart
I must have a knowledge deficit. Is the floor “flat” as in level or simply smooth and shiny? I don’t see some sort of leveling that extends between the machines doing the laying and smoothing. Something along the lines of a laser keeping the machines at a constant height. Floors look wonderful, but the last time I saw such an effort, it was to keep the floors smooth and perfectly level, such that a 5 story fork lift could feed racks without danger of falling over.
Imagine riding a skateboard with like 100 duro wheels on this. You’d never slow down.
Rick Sanchez would be proud.
I noticed (the guy not wearing a hard hat), that the senior workers get to ride the “cool-as-shit” riding trowel machines and newbies are on foot. 😀
Some hard hat wearing people were also riding the trowel machines, so.....and how do you know who's more senior at the job? Or maybe you saw what you wanted to see?
@@aaabbb-py5xd sarcasm man! Can’t people tell when someone is being a smartass anymore? Shit, this is a PC world. 😏
@@TAllyn-qr3io Lol, so when you're caught saying things about a video you had obviously skipped through, your defense mechanism involved (A) pretending you didn't mean it, and (B) pivoting from the embarrassment that was yours alone to a nebulous discussion of PC. Impressive, if only you'll learn how to use parentheses, that would be peachy.

1:44 its like watching construction in america one person working and 60 standing with shovels.
You gotta love construction.
That looked way more labor intensive than it should have been....
I had my new shop floor power troweled (polished) a wood shop for easy sweeping, so frickin slippery when wet it isn't funny lol, but still worth it.
The builders want to show the quality and professionalism of the construction. details make a difference! Judging from the dress of the staff and the quality of the staff, whoever believes is unlucky
I'm a lime putty plasterer and I would love to have a motorised float, they look like a lot of fun but totally impractical for me to have because I rarely do floor screeding and ceiling work. What's the cost of one please GWB?
Rick Sanchez: "True Level."
Certainly impressive!
Is this used in building semiconductor fab ?
Yes, not potato sheds.
Amazing they did all that in just over 4min. A country who built a full size hospital in 6 days.
Wow Great work
Why isn't there more women working here!! Equal work equal pay!!
Goya has buildings with floors like this in south Florida….
More and more concrete jungle. Probably an Amazon warehouse that will be populated and automated with robots.
А вот интересно, оплата труда у этих людей достойная?
Do regulations exist in China yet?
wow beautiful work!
Can't go on the concrete Gokart.
Why live?
Some of that work looks like it would be fun to do.
*I'm FLOORED!*
I work for a company that does that kind of work and man making them floors look like that takes a long time. Usually we start at 2 in the morning and them guys in those riding machines are on them till 5 in the afternoon. Specialy in the cold. I'm on the pour crew so we use the screed which is a cool machine but man this kind of work sucks.
Nice safety standards lol
Love the music.
2:28 someone buy this poor kid a new pair of jeans!
