Concrete Crisis: How We Saved a Floor Pour Gone Wrong!

[@GenosCP]

I batched concrete back in the day and every morning we would get a small metal pan of sand and another of rock. I would weigh them and then put them on a hot plate, cook all the moisture out of em, then weigh them again. From there you could calculate the % of moisture in the material by volume,and figure it into the batch weights. Made for very accurate batching. This was before all the fancy computers took over and you actually had to still use your brain for such things.. Good vid bud.

Mike , you’re a true professional when there’s a problem you address it with Calm and cool reasoning and come up with a solution…

[@Walkercolt1]

I've worked concrete when I was young and stupid. Just watching your crew makes my back ache!

[@cpdevon]

Good save! And good on you teaching the kid!

[@johnfahey7215]

Good to see the young fella hangin in there, slowly learning the ropes! Hang on to him, Mike, you know as well as I do, guys like him are few and far between! I worked with too many guys, all they wanted to know was, “When’s break? when’s payday? How long do we get for lunch?” AARRGGHH. Sickening! the Old Retired Laborer

[@boompa8267]

An amazing recovery and quick thinking. I love watching the professional's work. Have you ever poured a floor where you didn't even speak to each other it was all telepathy? Wicked good!

[@elconquistador364]

The calm soothing piano interludes threw me because the vibe so contrary to the pace of pouring

[@okgearheads3551]

You are a good teacher Mike! Your years in the trade are greatly appreciated.

[@TurinTuramber]

You and the boys make it look easy. 👍

[@aarongrabowski3775]

We always ordered more mud after a rain. We would run way short when pouring big floors and big walls. If its like a 100 yard you would run way short when all 10 loads are a little short due to wet materials. We also noticed that certain company’s yield’s were on the light side even with dry materials. And you know how bad it sucks having to wait on a balance. It can sometimes really suck. Especially when you run short on a stamped job.

[@andrewfrodo2086]

Great Video. Explaining the trade. Great to see all the young guys learning the trade and keeping those backs straightish

[@waltersantiago6978]

We run a Jonel batch system at our plant. Depending on the plant and how serious the operation is where you get the mud, everything needs to be inspected consistently. There is no room for error when you’re trying to provide the best concrete for our customers. That being said it is possible that sand moisture probes haven’t been calibrated or we have to undergo weigh scales calibrations for our agg, cement and water scales 2x a year in order to ensure batch weights are accurate. To answer why you’re getting rocky mud some days and good mud another, I would say the problem starts with contaminated materials or agg bins. We had a hole form in our con agg bin that would leak into our con sand. We caught it when we got a call from a customer stating that the mud was really rocky. Looking into the problem we found that hole where the material would run off our turn head chute against the wall of the bin. So I guess it is all about communication and having a good company who takes pride in providing the best concrete possible for their customers.

The new type 1L Portland cement is causing headaches. Additional limestone added seems to be causing more separation issues especially if fly ash is added. Nice video!

[@DuyenLe-gn1fi]

Hey brothers! It is beautiful seeing you guys working together peacefully. Love! ❤️ 🙏

[@dannyboy2180]

Mike, very lucky. Great crew!!

[@joelenehopkins1564]

I was a little nervous toward the end but it ended up being perfect! Great job!

[@Yorkie285]

Hats off to your great crew. They are good workers who know their stuff.

[@Austin-fc5gs]

Do you ever do insulation on the bottom as well as between the slab and the stem wall?

[@shawnwood9875]

Good education on the moisture content!

[@PhilPrater]

Another nice job, by you and the crew. You bought a lot of water.

[@SSLaser92436]

What is the large void at the garage end? Seems you would eat up some extra concrete there.

[@philleach6271]

How come you guys leave the re bar on the ground?

[@redryder8834]

Fun fact: Wet gravel or sand is about 800 lbs heavier per yard than dry

[@tedrowland3840]

Very pleasant music and great work and recovering a dilemma!😂

[@elbuggo]

Water/cement ratio - weird that the most important parameter in concrete is so hard to measure. Professor Tyler Ley has a solution with his Phoenix gadget - if interested: _Measuring w/cm in concrete with the Phoenix!_

[@clivehorridge]

A good supplier should be using a drier and batching dry weights, according to the code. That’s what I’m used to, but I’m not in Merica. Good job guys. ❤️🇷🇴

[@DIYDaveT]

Well it turned out absolutely beautiful.

[@DaveNotInCali]

why is the wire laying on the bottom?

[@sholle9588]

Vibrator, Air content for the heating system?

[@roncarter7290]

They are supposed to do cook outs to know the moistures before batching

[@johnypitman2368]

I have a buddy in the biz and he tells me that the concrete supplier now backcharges for taking back extra crete. I never experienced that BS thank goodness. very few flatwork pours can be calculated without a plus- minus of at least 5% so I always ordered extra. Only once did i underestimate the needed concrete and fortunately they got me the extra load on site asap, bottom line is extra concrete is a must. I have seen people throw rocks and such into the footings as they are poured but that is a sure sign of unprofessional ethics

[@elbuggo]

Concrete professor Tyler Ley talks about aggregate moisture correction in his videos _Aggregate Moisture Corrections pt. 1_ and _Aggregate Moisture Corrections Pt2 - Example (with Excel Sheet)_

[@Caribbeansurfbro]

I also work with concrete, I'm down in CR where it's warm in the winter and hot in the summer and we pretty much do it the same way...do you guys have to do all the rebar and stuff or does the builder? We don't we just pour and finish

[@mikahpreston1160]

Almost like you guys did this before.. Looking good

[@mattschoular8844]

Please pass me the concrete stretcher. Nice work Mike

[@The_Aussie_Enquirer]

Reinforcing mesh should not simply sit on the ground when used in concrete slabs. It needs to be placed in the middle or upper third of the slab to ensure it effectively strengthens the concrete. This placement is crucial because it allows the mesh to resist tensile forces that occur as the concrete sets and dries, preventing cracking and structural failures. Typically, supports are used to keep the mesh at the correct height during the concrete pour. Proper positioning of the mesh according to the specifications of the project ensures the structural integrity of the concrete.

[@WombleUK]

Blimey there is some serious gaps/flex under that insulation towards the edge of the slab @7:40 that has to weaken the slab with a decent void underneath it. Especially when that appears the garage floor entrance. Well main thing is you got over the issue & didn't go into panic ranting mode.

[@redryder8834]

Good eye. That’s gonna crack, why would it be designed like that?

[@vernbolstad3956]

A lot of the same problems from spring to fall in wa. For gypcrete.

[@roblamont8756]

That’s tough work 💪🏼

[@paullasko2023]

Wow, that was really close! Are you writing the video descriptions with AI? Sure reads that way.

[@danpaddyandy6150]

Mike ask the batching plant to calibrate the moisture probes in the aggregate bins! This may be the reason why mix is stoney some days?

[@earlmiller6093]

So glad I don’t do that work anymore….. did it for years… hated it…. Still hate it…. Now have my own machine shop… work at home … by myself. Never will hire anyone… a one man shop busy making metal parts…. He’ll of a life!!

[@robertnash2446]

I always worry you will cut the radiant tubing somehow during the pour.

[@lewismescudi1404]

‘High range water reducer’ Aka pissing it up. Good job chairing up the mesh boys

[@calj01]

All of that could have been eliminated with overhead screeds. they make hangers that clip onto the stakes so no nailing. Just slide tha screed down, a tamp person removes them as he goes.

[@jameshines6486]

The concrete in St.Croix. U.S Virgin isla ds is usually mystery mix.

[@matthewbattie1022]

Styrofoam compresses and your subgrade lowers. Add 3 to 5% when pouring on foam.

[@GenosCP]

Incorrect. This is either XPS or prodex, which holds up to 1400 lbs per sq.ft. without compressing. Concrete weighs about 50 lbs per sq.ft. at 4" so it will not change the the yield of the pour.

No rebar chairs?

[@MikeDayConcrete]

No

[@stayready5403]

Great crew but after 40 years of finishing concrete in the Arizona heat where you have 2-2.5 hours to getter done after that first rock hits the ground it’s just way different. We literally have to just haul ass every minute.

[@johndorazio3759]

Wouldn't they just put less water when they mix it up

[@clothedwiththesun]

Tough boys!

[@Anonymous-ff5wr]

I wanted to try the cute method for years my old owner won’t hear of it. As for batching because of wet material it’s all calculated in thats there answer I still don’t believe it

[@mikeduffy4589]

The driver probably got loaded with leftovers. It's all an educated guestimate when the batch man asks what's he got left on. Always make sure to require the weights be on the ticket.

[@redryder8834]

Leftovers on Monday morning?

[@kirkdunn1379]

keep 3 or 4 sacks on the trucks maybe.....

[@ELPeeDubYou]

Driver looks hung over and indifferent 😂

[@robinhood4911]

I am not a specialist in making concrete floors, so my comments may be wrong. In my opinion, the people who poured the concrete did their job well, but I don't think that the others responsible for the effect of this work did it well. As it was noticed, the concrete contained more water than it should, which means the quality of the concrete is poorer. There is a reinforcing wire grid placed on the floor insulation and as you can see, it touches the insulation (there is no distance between them). In this case, the wire reinforcement will only be glued to the lower side of the concrete, and it should be "embedded" in the concrete at a certain height, therefore "spacers" should be placed under the wire grid so that the concrete flows under the reinforcement. In this version, this reinforcement is worthless and only increases the construction cost (time of laying the reinforcement and its purchase cost). In my opinion, the person laying the wire reinforcement should put spacers in the appropriate amount. Currently, there are concretes with added glass fibers and in such cases metal reinforcement is apparently unnecessary. There should be a small barrier between the floor and the walls (e.g. 2 thicknesses of felt) to prevent the concrete from cracking uncontrollably (concrete shrinks and cracks naturally, although the newest types of concrete, maybe, but I'm not sure, don't have this problem). After the concrete has dried (when it is sufficiently hard), the concrete is cut (about 1/3 of its depth) with a saw so that the cracks are in these cuts. Of course, these cuts are later filled with appropriate material. The distance between these cuts should be 4.5 m to 6 m (14 to 20 feet apart). The concrete foundations we see in the video should also have space for cracks (if we want to have control over their sealing), but that's a different topic. All objects emerging from concrete (pipes, manholes...) should be separated from the concrete with plastic foil so that they do not stick to the concrete. After the concrete dries, these gaps are glued using e.g. silicone to seal these places and prevent the passage of gases from the ground to the interior of the house (e.g. radon).

[@simonclare333]

Surely it obvious the rain effects the weight and volume. The lorry can still only take a certain weight. Weather that’s water or material. Come on lol

[@aptpupil]

You're a good boss

Funny to watch as a high rise carpenter. We do raised floors on top of the slabs and many times the floors way the fuck off! Lol Guess they care less for industrial office buildings or there’s not much they can do about it 🤷

[@luismorua859]

When he’s screeding and he has extra concrete on the edge of the screed he can use his feet and pull the concrete inside, that way he doesn’t have to stop screeding. Unless is too much then yeah stop let the helper pull the concrete.

They only do flat work. They don’t do the form work.

Is it at all possible to lower the volume of the clips with the laser level and the trucks reversing? I love binge watching your content but I constantly have to spring for the volume button like a maniac to not wake up my wife or disturb whoever is next to me

[@webworkhere]

[@jimburns2596]

Yeah over our way we usually put any shortcomings on the mixer driver. Because he knows what the sf of the job and how thick the slab is ect. Driver's also pay attention to the moisture in the sand lol. Call the batch guy and question him.

[@Brendannolan1986]

Truck driver had no idea what he was talking about. Typical. He would’ve been hosing it down around the corner to make his truck clean up easier. Classic move

[@mrdavidurquhart]

Driver wouldn't know exactly what batcher gave him if he doesn't have scales. The water reducer they ordered probably reduced the volume in transit and when it was being discharged and worked. The high slump they ordered may have seen more absorption into the ground. I'm just guessing. How good are his calculations and what margin did he over-order? We don't know. You can't wash up right at the form work. In Australia that job would have had a pump. Impressive chute!

[@TrunkyDunks]

As a building inspector, the pour looked pristine. Just don't like the pouring over the standing water and under the foam? that should be pumped out. But over all, with the fiber mix, should be fine.

[@chrisbull2501]

Building inspector happy with reinforcing on the ground!

[@TrunkyDunks]

@chrisbull2501 you don't need chairs on a pour like this. It's a radiant heated internal floor, and it has plenty of reinforcement. I'm sure their mix was strong enough and may have had extra admixtures.

[@chrisbull2501]

You definitely need chairs the mesh is on the ground, keep up the good work mate

[@TrunkyDunks]

@chrisbull2501 you don't, you just lift up the mesh and tie it different. It's literally in the RBC handbook

Those are not “facts”. Wet sand or gravel will always be heavier than dry by about 800 lbs a yard
