Simple explanation: the concrete finishers added water to the top of the slab because the concrete set up too fast. The cream layer they created with the surface water didn’t bond with the set concrete below. You will probably have a lot of other areas popping off soon.
sometimes too much air entrainment can cause issues like bubbling as the concrete is troweled, if it was tearing when machine troweled generally a slight misting of water can work, the other thing, is applying a curing and sealing compound immediately after finishing is completed, low slump mix with a water reducer will give workability and maintain strength. Lots of variables!
Did they use any curing agent or anything out of a pump sprayer? Most of the time they use the wrong one and this is what happens, potato chip surface peels right off...however.....using this technique is great when removing the surface peels creating great adhesion for a cold joint installation. just saying , also did they use a super trowel?
Tommy Francis highly doubt it was air entrainment. By the looks of it the warm windy day made it set up too quick for them to keep up with it with 3 walk behind trowels and they had to splash water on the surface to work up a paste to get a finish on it.
Being in the heavy highway construction project management field and working for one of the largest international civil engineering firms I can tell you this is from placing additional water on top of the concrete surface while finishing it. This is the reason you’re contractor is so willing to saw cut this section out and re-pour it. Additional water segregates the cement from the sand causing a weak area in the surface called spalling. It happens from time to time and the other part of the slab looks good. He was right in doweling the slab to the existing slab but where is the wire mesh / rebar? The entire slab should of had wire mesh or rebar in it. You may have used fiber mesh but with that size slab and having equipment weight on it, they should have installed heavy duty wire mesh at the minimum. The finish work looks great and I wish you all the luck with the project. 🇺🇸
I agree with Dennis Concrete is my life. No sense issuing blame, honestly, this happens quite often, pump operator could have added too much water, the plant could have messed up that truck's batch the contractor could have, u know. Mistakes happen and yes, you do have yourself an A+ contractor. A good honest contractor is like gold you hang on to em, congrats on the mega shop! I'm Impressed!
It is not from water, it is from over working the slab, air is trapped below the surface and causes the paste to peel off. Been finishing concrete 21 years, it is a finishing error.
Somebody either messed up and gave you Fly-ash or slag cement instead of portland cement! Or a driver blew a load into the wrong silo! So if I'm right, you'll still have problems later because he didn't get it all it would be a whole load or multiple loads. I hope it was just a load and he figured out where it was so you don't have to deal with it again. Might want to save some of what he tore out just incase you need a sample.
Yep, $70k was way too much, especially without rebar. I was quoted on a 30 foot x 30 foot slab 6 inches thick with rebar for a little over 8 thousand bucks
I have no idea with prices on concrete but everything is 5 times as expensive is it was four years ago. I’m not saying that isn’t a high price but that could be a factor.
I was a concrete tech for years in the NW for years and addressed many such issues. First, a question. You mentioned "a frosty morning." Is it possible that the surface froze within the first few days after being poured? That'll do it. Excessive water finished into the surface...either bleed water or added water while finishing will also affect surface strength and bond. Suggestion...take a chain and drag it over the entire surface. A bonded surface sounds hard and steely. A delaminated surface sounds hollow. This will help you find other problem areas. Sorry to say, this was a placement problem and not a supply issue. I hope the problem is not affecting a majority of the surface. Good luck.
I would agree, he needs to run a chain over the entire floor. It is posit was an add mixture problem and only affected one load. In any case he needs to know if it is the entire floor or just one area.
@@fredr6381 not likely unless there was alot of air in that yard. I guess it could be possible with the other issue the old concrete causes by itself. I would really be concerned about the rest of the floor. If it were mine I would at least do the chain but would probably get a pressure washer out as well.
Reminds me of Freezing on the top are using to much Calcium and it setting up to fast in Cold Weather , You will have more to flake later , It could be a year from now , Not sure how deep it is however the best and costliest Way to fix is to pour 4'' on top of that above freezing temps and Seal it for slow curing ,
While anyone and everyone should appreciate the contractor standing by their work, those are literally the exact problems I was talking about in the pour video that could have been avoided. Maybe they will get lucky and have a ticket from the batch plant showing they screwed something up at batching, but overall, spalling like this is indicative of them adding too much water on site to make it easier to place, in conjunction with bad mix design. Unless you had a bad freeze the night or two after it was placed, which can cause surface issues before it's cured, this shouldn't happen. People accept it because they are used to seeing it. But keep in mind, I have placed thousands of yards of concrete for civil and substation, failures like this are not an option, so they did not happen. Yeah, forms blew out, concrete got spider cracking on stupid hot days if cure wasn't applied in time, but these issues will likely not be limited to just that section of the slab.
John....Main thing is that Wray's Concrete stood by their work...you can point fingers in every direction...but as long as he stood by his work...I'm happy as a clam
@@StoneyRidgeFarmer that's the key, provided it's rectified in a manner you approve of. Granted the best problems are those that are caught and fixed before the finished product.
@@StoneyRidgeFarmer While that's commendable, if it is from adding too much water on site, the rest of the concrete will fail prematurely as well. Adding too much water to save manual labor is unacceptable and these companies need to be held to a high standard, or else everyone else will get shoddy work as well.
@@lifeIsTemporaryHere I'll guarantee that's playing into it. Another thing is, I'm not one to believe in coincidences, so if this just so happened when a camera was on them, how much crap happens when the camera isn't on them, that doesn't get exposed. Another thing is, how many customers wouldn't even have said anything and just let it go. I watch another RUclips channel and he just moved into one part of a several bay metal building his buddy had put up. Within a couple months of it being up, you can see cracks all over in the concrete and he's never addressed it, or got it fixed, so apparently they're just letting it slide. Probably a half million dollar building and it's already falling apart a couple months into it. People are so used to getting piss poor work, they don't even say anything anymore, most of the time.
Your vid title seemed to be a complaint about a HORRIBLE contractor. Glad you got a good one! I feel the same way about my mechanic. My AC was blowing hot and cold. I brought my truck in to a shop chain, they told me my ac compressor was shot, $800 to replace. Nope, not in my budget. Few months later I took it to a Local, 1 shop business, told him, AC blowing hot/cold. Did not tell him about the other shop. He took at look at it, told me to come look at it. There was a loose connection, he plugged it in, ice cold ac, no problems. He did not even charge me for it. He has been my Mechanic for 15 years. A good, honest businessman is worth many times his weight in gold, hold on and never let go of them :)
Too much water applied on-site bc they didn't quite have enough concrete, or too cold and it wasn't covered, so the surface froze. That's what happened at my brother's house build. For all those praising the contractor, it helps when your customer has 640k followers on YT. Influence brings out the better in people.
Sorry this happened. I had a shop built 45x100 and the whole slab delaminated. I had to hire lawyers to get it fixed as the contractor wouldn’t stand by his work. Blamed it on the concrete and the concrete company said it was contractor error. I have infloor heat. They ended up pouring another 5 inches on top of the existing 5 inches. Ended up with 10” of concrete. Good luck looking good.
Yes it took a long time for the initial heat as the concrete was poured in November. It took three weeks to get it up to temperature but once it was up to temperature my boiler didn’t run very much. Lost power for 3 days once and only lost 5 degrees in the winter.
Entrained air at the batch plant could be your culprit. You can’t do a hard steel trowel finish on air entrained concrete. It will delaminate every time. Make sure they didn’t divert a truck that was batched for a wall or sidewalk pour. You need entrained air in a wall or exterior concrete that will be a broom finish.
I had a driveway do the same thing happen and mine was due to a bad batch of crete. It turned out the company that made the crete screwed up and it took me 2 yrs but I did get a new slab poured. But like I said mine was from a bad batch and I wasn't the only customer with the problem.
I was worried when I saw there was NO rebar web n the slab! Like John Doe says, it appeared the pour did not go well and in a timely manner. Over worked top surface, concrete that set off too fast- everything was wrong, no matter how good you think the contractor is. The slab is underengineered; there will probably be problems forever with this slab.
He is saying the lack of rebar web is an additional issue you may have down the road along with other things that may have gone wrong during the pour. The flaking as most have said was water added and/or overworking to try and save the pour.
@@StoneyRidgeFarmer that not what he said.. "I was worried when I saw there was NO rebar web n the slab!" like everyone he start watch for the train reck. why it spalling he said "Like John Doe says, it appeared the pour did not go well and in a timely manner. Over worked top surface, concrete that set off too fast- everything was wrong, no matter how good you think the contractor is. The slab is underengineered; there will probably be problems forever with this slab." it hurt me when went back watch the pour of this pad.
You don't need us to tell you the issue. Just go back and look at the slump for this placement as opposed to the others. I'll avoid making predictions but the durability may be similar throughout the other parts of the slab. Regardless, wish you the best on the remainder of the build and here's to no more spalls, cheers!
I was a contractor for many years and always stood behind my work it’s just the right thing to do. It pays off doing so because people love to tell others of a good experience they had with a contractor. Unfortunately there are a few bad so called contractors out there giving good people a bad name. Nice to see an honest person.
Those older toyota 4x4s with the 4 banger motor and 5 speed are perfect farm and hunting trucks and beats side by sides in comfort As a concrete inspector in past I ran into that issue and ended up being bad sealer sprayed on it which affected the curing.
SRF totally lucky as hell! As said, a man's true value is done by a contractor's action... nothing better than completing a job as promised. Truly a rare item to experience in today's time and age! Thanks for the background, leading to understanding the reason why... paid his time to truly show his face values, a bankable item!
lol...I'm not sure about luck...but I do understand that I have an expectation of my contractor and he has high expectations of himself...pays to get the best..not the cheapest for sure!
We've had a lot of concrete poured on our farm in the last two years and each prep and pour was different than the other. Seems to be no standard in the industry. Good that Ray will redo it, but I feel like you are going to battle this delam issue throughout the life of this building as other areas pop up. Sucks man, because concrete ain't cheap but it is permanent, so you have to live with that. Hope they install the building correctly.....
Without rebar or wire I think your going to have problems keeping the sections of floor level if the concrete cracks in the joints and settles.That is one of the reasons it is put in there to hold the concrete together if it cracks.. Up north here, it is required for that size pad. Your concrete contractor might be good but I think he messed up on the call not to use it.
@@kevincostello4991 McDonald's drive thru is not a structural slab, this is. This slab will have a heavy steel super structure built on top of it with forces pushing and pulling in all directions.
That’s an unmixed lump of Portland cement that didn’t get mixed by the delivery truck. A problem not anyone’s fault except happens somewhere in the supply trail of the Portland cement. A common example is old bags of cement in Home Depot. You cut open, moisture got in and there’s a grapefruit sized lump that won’t break up. Same here.
Wow, this is great that Wray's is standing by their work and supporting a veteran-owned business is awesome. Interesting to watch the whole process come together!
Dang Josh, sorry to see this..at least they are standing behind it...dont know if I could live with it, feel like there is more delam coming...think I'd have to ask them about a full rip out and re-pour, huge I know, but man just thinking potential what if's down the road. Hang in there, your great attitude is an example for many.
Nice to see integrity in a man. It might have to do with being in the service, but more likely the way he was brought up. In the end his name is on the finished product. If it is unsatisfactory, that's his name..... Josh, thanks for taking us on this journey.
My in laws built a brand new house. 6 months later they had foul smelling water puddles in basement. Turns out the sewer lateral was put in wrong and backed up. Needless to say, insurance got involved and everything had to be ripped up
I thought, by the title of this video, it was going to be a negative video where the contractor didn't back their work. I am so glad for you Josh, that I misunderstood the title and these folks backed their work. This is refreshing to see!
The leaves are off of the trees. It looks cold there. And the temperatures go down at night. I read one guys post saying that there wasn't any rebar. In the long run; it will eventually all fail without the rebar.
Too much cream on the top or Butter, Its caused by too much water left on the top. Like you said water pocket with concrete butter. Thats cool he's fixing it
Glad you had someone that cared about the work they did and the workmanship they did we had a 30 by 50 put up and they put the concrete in and cut it in 10 foot squares and it was supposed have wire in it but after 6 months the hole 10 foot slabs started heaving and moving up and down I called the contractor and he told me for the money we paid we got exactly what we ordered they never did nothing about it we ate the money so very glad you are getting a good concert floor love your channel ❤
I would say a combination of too much water in the mix and over working concrete to try to get a perfect Finnish. It is just something that happens sometimes!! But if your contractor is Making it right you hired the right guy!
Hi this is Tom Haus from Concrete with a Hauses one of my viewers asked me to watch your video and give a comment. After watching the video and saw it was power troweled.I feel there is too much air in the concrete there should be low air or no air when power trailing a floor. The surface will start the blister and delaminate exactly what you are showing us. A simple test is to take a golf ball and walk around the slab bouncing it and listen for that hollow sound under the surface of the concrete you’ll know when you hear it. A better test would be a petrographic test unfortunately there about $800-$1200.if you could check with the supplier to see what type of air entrainment was in the concrete that would tell you a lot.if I’m any help that’s my intention if you would like to talk further email the office
Tom, you're saying they basically burned the surface by power troweling ??? Tom, do you think that it could be the plants fault for adding to much fly-ash ???
We had a large amount of concrete poured that had issues with spalling. The issue was the plant ran the batches wet that summer and we had intense heat. The two factors caused the cream to come to the top, and the water evaporated out leaving an uneven cure. That resulted in the top chipping off and exposing the rough aggregate underneath.
We built a Garage Bigger then this and the floor did the same thing. It was not the contractors fault that did this it was the mix got messed up at the plant. If you take a test of the concrete and send it in every time you pour, this will allow you to know ( if there is a problem) where in the process it is. We had to take out the floor and the Plant footed the bill and made it right.
hi there i found it really does no mater weather it is . a contractor or my self . when something big (or small) goes wrong or happens it seems to take a bit of your heart . been there to many times , it just makes a new plan start . looks like you worked threw it well . hope for smoother sailing john
just had a 25 x 40 pad run for a shop with a 10ftout for a breezeway between another shed my rebar is about 3 ft apart wire tied and i am Not planing on putting heavy equipment on it !! I too am concerend that if didnt see full rebar runs across the cut out areas!!! my slab cost me 7500 just to give an idea of the costs of concrete!!!
your pad won't be in a climate controlled shop though? Frost heave would be the only concern...but we have footings and we have rebar in several places
I had to plane 1/2" off a slab in a court house. The concrete looked the same. If you hit it with a hammer It would sound hollow. I was told they burned the concrete with the power trowel. Running the planner over the entire second floor.
You should take a small hammer and gently tap on that slab in a grid pattern. Anywhere the surface is separating will sound very different from solid concrete. You can even drag a rod across it and listen. It will make a kind of ssssssskskskskssss sound when you hit a loose spot.
Just what I was thinking. Bro. Larry couldn’t afford to have those 640,000 subscribers know he didn’t make it right. He’s probably an honest guy either way.
Larry looks like a Marine. I'm proud that he has my last name. Josh, I am an Air Force Vet also. I was a 46150 Munitions Specialist. Served on Okinawa 1948-59. Veterans helping Veterans, it don't get any better Woooooo!!!
I though that that pour was too Big Josh, I think it should have been done in small section. I'm glad they came back for you. Good thing you have this a You Tube Channel. I think the cream as they call it had too much water and maybe they did not work it enough. I would have installed fiberglass strains to the mix and rebar and heavy wire, Josh. I you park heavy equipment in there over time you might get more cracks. I had a Cement company use fly ash in there mix and it caused spalling. They use fly ash as a filler added to the concrete.
Water cement ratio , I’m guessing it was pumped and often if the pump plugs or to much fall aggregates separate along with the water . There’s a 100 ways to screw up a slab and I’ve done 101
I agree with u josh s. Looks like they got a little behind finishing it and if they did squirt water on the surface when they were finishing creates a bad bond at the top quarter inch or so.
A friend who was an electrical contractor always says to double your price do half of the work but to make damn sure you did great work because people will forget high price a whole lot faster than they will shoddy work.
That is always a problem with power floating just run a wide float over when it just going off and that will do over working concrete it can go wrong top contractor standing by his work nice one he is a keeper:))
That's a Marine for ya. We take pride in everything we do and have integrity. Instilled in us the day you get to Paris Island for the rest of your life. . Semper Fi Larry👍
Good Day, I used to own my own business as a Concrete Contractor for 17 years, & gave it up after the 08’ economy down fall, but still dabble in it ever so often, actually getting ready to build my own Shop not as big as the mega shop, but congrats on the new building, but as far as my experience is that those flaky areas thru out the slab is caused by to much air in the mud as an interior mix. What was it the contractor told you?
I wish that he would learn the difference between another and any other. It's a misleading title but for how many times he repeats it in the dialogue I really wonder if he understands the difference in meanings. That could lead to some pretty poor miscommunication situations.
the cap was burned. I've seen this several times by overworking the finish. I bet they put on the power trowel at least 3 time ( or the ride on) . also looks like they used the pans on the bottom and this will seperate the cap as well. Spraying on extra water after the concrete was set will do this. I won't let a power trowel on three time I prefer a wacky trowel.
To me it looks like the blistering on the concrete is caused buy Power trolling air entrained concrete you have to be careful how you power troll air entrained concrete to avoid blistering that's my opinion
It looks like it froze. Did they cover with blankets? I still think that 70k was a little pricy to form and pour but like I commented before I don’t know the prices in your area. Awesome that they stood behind there work. I’m a general contractor started in concrete and Red Iron buildings. That’s someone who backs there work.
Yup! $70K was way over priced for a concrete slab with no rebar. I did a 25'x28' 6" slab with rebar, that was about $6.5K last year. $70K would be a great deal if it includes the cost of the pad & building.
Several different reasons this could have happened.. from the mixture at the plant to added water etc… main thing is like you said he made it right!… also possibility of it cracking in different places off of the expansion joints.. another common problem.. good contractor though for coming back and making it right!
Hi josh to much air in the mix my neighbor has a new slab 50 x 60 the whole slab did that. concrete won't do a thing about it. then I plowed the slab this winter and I was plowing the whole top layer off
Another thing that can cause this problem is if they tried to finish it too early- before the bleed water came off. On a large slab, you can get different sections that cure faster than others, and some that set up more slowly. Anything that will cause excess water on the surface of the slab will weaken the mix there and cause spalling later.
Dammm... Crazy, I was looking for the follow-up on this pour, and here it is in my feed. Glad you have a solid guy, tho. I do see problems without having rebar in that big of a pour. I recommend you get some independent tests done and see if this is a plant problem. Also, going forward on pours of this size you should have a test company on-site checking each truck. Definitely add the rebar. We would of used #4 or #5 12 inches on center. Good Luck
@@StoneyRidgeFarmer no you're right, but 19 years ago when I joined the military, it was just expected that you do the best you can and going above and beyond was the norm.

Hi Josh, I’m no expert in concrete but if it was me, I would be concerned that other areas of the concrete might rear its ugly head with spalling. I would hate for your building erector to put up the building and then shortly afterwards, you notice more spalling in other areas.
More like , “Contracters don’t want to work too hard troweling a slab, so spray some more water on it.” Or, “Hey driver, put 100 gallons of water in it.”

Thats from using water to finish cement. They weekend the mix and it got cold. They should have should used chemicals instead of water. Then they should have used heaters and cover with concrete blankets
I would say too much sir in the mix ...then it peels when troweyed..than you put water on while trowling and it doesn't bond...then the frosty and freezing cause this isdue
Local machine shop was getting a new CNC horizontal mill and the 3’ thick footing that was 10’ below grade had to be busted up and re poured with an excavator in the middle of their shop because when the tech came to install the machine he dropped a leveling pad and didn’t like the way it sounded when it hit the concrete. Sure enough when they cored and tested the sample the concrete was not the right grade. Concrete contractor replaced it all on his dime.
if concrete mix didn't have "air entrainment" added to mix prior to pouring this will sometimes happen to surface if water lays on it and it freezes. Adding low air in the batch helps with this here in ohio till winter is over. But hard to get a nice slick finish with air added to mix. It likes to peel finish as they are finishing slab if they stop the trowel machine for a second. Nice they backed up their work! Slab looked great
I have worked with several contractors.I have had my share of seeing bad work . I we’ll do my own work b4 I pay someone else to do it .I’m building my own log house now and it’s taken way to long to get it all done but at least I know it we’ll be right

@@StoneyRidgeFarmer that's the key, provided it's rectified in a manner you approve of.
Granted the best problems are those that are caught and fixed before the finished product.
@@StoneyRidgeFarmer While that's commendable, if it is from adding too much water on site, the rest of the concrete will fail prematurely as well. Adding too much water to save manual labor is unacceptable and these companies need to be held to a high standard, or else everyone else will get shoddy work as well.
It would be nice to see if this is his practice or just for those with 650k followers. I really want to think he’s like this with all his customers.
@@lifeIsTemporaryHere I'll guarantee that's playing into it. Another thing is, I'm not one to believe in coincidences, so if this just so happened when a camera was on them, how much crap happens when the camera isn't on them, that doesn't get exposed. Another thing is, how many customers wouldn't even have said anything and just let it go.
I watch another RUclips channel and he just moved into one part of a several bay metal building his buddy had put up. Within a couple months of it being up, you can see cracks all over in the concrete and he's never addressed it, or got it fixed, so apparently they're just letting it slide. Probably a half million dollar building and it's already falling apart a couple months into it. People are so used to getting piss poor work, they don't even say anything anymore, most of the time.
A better looking mix coming out of the truck this time than the first pour. Not as wet as the first.
@@haroldphipps3457 The less water in the mix, the stronger the 'crete. The crete has voids where the water was when it dries.
Your vid title seemed to be a complaint about a HORRIBLE contractor. Glad you got a good one!
I feel the same way about my mechanic. My AC was blowing hot and cold. I brought my truck in to a shop chain, they told me my ac compressor was shot, $800 to replace. Nope, not in my budget. Few months later I took it to a Local, 1 shop business, told him, AC blowing hot/cold. Did not tell him about the other shop. He took at look at it, told me to come look at it. There was a loose connection, he plugged it in, ice cold ac, no problems. He did not even charge me for it. He has been my Mechanic for 15 years.
A good, honest businessman is worth many times his weight in gold, hold on and never let go of them :)
Too much water applied on-site bc they didn't quite have enough concrete, or too cold and it wasn't covered, so the surface froze. That's what happened at my brother's house build. For all those praising the contractor, it helps when your customer has 640k followers on YT. Influence brings out the better in people.
Sorry this happened. I had a shop built 45x100 and the whole slab delaminated. I had to hire lawyers to get it fixed as the contractor wouldn’t stand by his work. Blamed it on the concrete and the concrete company said it was contractor error. I have infloor heat. They ended up pouring another 5 inches on top of the existing 5 inches. Ended up with 10” of concrete. Good luck looking good.
So your lines have to heat twice the mass I guess. Does the heat work OK?
@@tomjones4318 my thoughts as well
Yes it took a long time for the initial heat as the concrete was poured in November. It took three weeks to get it up to temperature but once it was up to temperature my boiler didn’t run very much. Lost power for 3 days once and only lost 5 degrees in the winter.
Entrained air at the batch plant could be your culprit. You can’t do a hard steel trowel finish on air entrained concrete. It will delaminate every time. Make sure they didn’t divert a truck that was batched for a wall or sidewalk pour. You need entrained air in a wall or exterior concrete that will be a broom finish.
Andrew Camarata would've poured that slab by himself and saved 68 grand 😂😂
💯
😆🤣👍
No doubt about that. That man is a genius
And put zero relief joints or cuts.
@@MustObeyTheRules right, he woulda poured it in there that's about it lol
I had a driveway do the same thing happen and mine was due to a bad batch of crete. It turned out the company that made the crete screwed up and it took me 2 yrs but I did get a new slab poured. But like I said mine was from a bad batch and I wasn't the only customer with the problem.
If that was the problem it would have been all of the 90+ yards so try again!!
I was worried when I saw there was NO rebar web n the slab! Like John Doe says, it appeared the pour did not go well and in a timely manner. Over worked top surface, concrete that set off too fast- everything was wrong, no matter how good you think the contractor is. The slab is underengineered; there will probably be problems forever with this slab.
If he runs a chain across it I guarantee it sounds hollow. It was not finished properly
my my....you guys sure can tell alot from the couch cushion lol....no rebar most certainly didn't cause flaking
He is saying the lack of rebar web is an additional issue you may have down the road along with other things that may have gone wrong during the pour. The flaking as most have said was water added and/or overworking to try and save the pour.
@@StoneyRidgeFarmer concrete is a science. People aren't just guessing in comments they are correct
@@StoneyRidgeFarmer that not what he said.. "I was worried when I saw there was NO rebar web n the slab!" like everyone he start watch for the train reck. why it spalling he said "Like John Doe says, it appeared the pour did not go well and in a timely manner. Over worked top surface, concrete that set off too fast- everything was wrong, no matter how good you think the contractor is. The slab is underengineered; there will probably be problems forever with this slab." it hurt me when went back watch the pour of this pad.
You don't need us to tell you the issue. Just go back and look at the slump for this placement as opposed to the others. I'll avoid making predictions but the durability may be similar throughout the other parts of the slab. Regardless, wish you the best on the remainder of the build and here's to no more spalls, cheers!
I was a contractor for many years and always stood behind my work it’s just the right thing to do. It pays off doing so because people love to tell others of a good experience they had with a contractor. Unfortunately there are a few bad so called contractors out there giving good people a bad name. Nice to see an honest person.
Those older toyota 4x4s with the 4 banger motor and 5 speed are perfect farm and hunting trucks and beats side by sides in comfort
As a concrete inspector in past I ran into that issue and ended up being bad sealer sprayed on it which affected the curing.
SRF totally lucky as hell!
As said, a man's true value is done by a contractor's action... nothing better than completing a job as promised.
Truly a rare item to experience in today's time and age!
Thanks for the background, leading to understanding the reason why... paid his time to truly show his face values, a bankable item!
lol...I'm not sure about luck...but I do understand that I have an expectation of my contractor and he has high expectations of himself...pays to get the best..not the cheapest for sure!
We've had a lot of concrete poured on our farm in the last two years and each prep and pour was different than the other. Seems to be no standard in the industry. Good that Ray will redo it, but I feel like you are going to battle this delam issue throughout the life of this building as other areas pop up. Sucks man, because concrete ain't cheap but it is permanent, so you have to live with that. Hope they install the building correctly.....
Without rebar or wire I think your going to have problems keeping the sections of floor level if the concrete cracks in the joints and settles.That is one of the reasons it is put in there to hold the concrete together if it cracks.. Up north here, it is required for that size pad. Your concrete contractor might be good but I think he messed up on the call not to use it.

That’s an unmixed lump of Portland cement that didn’t get mixed by the delivery truck. A problem not anyone’s fault except happens somewhere in the supply trail of the Portland cement. A common example is old bags of cement in Home Depot. You cut open, moisture got in and there’s a grapefruit sized lump that won’t break up. Same here.
Love to hear good/positive accounts about contractors with integrity.
Wow, this is great that Wray's is standing by their work and supporting a veteran-owned business is awesome. Interesting to watch the whole process come together!
Dang Josh, sorry to see this..at least they are standing behind it...dont know if I could live with it, feel like there is more delam coming...think I'd have to ask them about a full rip out and re-pour, huge I know, but man just thinking potential what if's down the road. Hang in there, your great attitude is an example for many.
Larry rocks! Concrete got too wet. Puddled upon finishing.
Nice to see integrity in a man. It might have to do with being in the service, but more likely the way he was brought up. In the end his name is on the finished product. If it is unsatisfactory, that's his name.....
Josh, thanks for taking us on this journey.
My in laws built a brand new house. 6 months later they had foul smelling water puddles in basement. Turns out the sewer lateral was put in wrong and backed up. Needless to say, insurance got involved and everything had to be ripped up
Drag a log chain on the surface to find other surfaces the sound will be different sound of hollow
Semper Fi Larry! We need more folks like you. Thank you for you service.
Integrity says it all, good for you and the company for doing the right thing.
I thought, by the title of this video, it was going to be a negative video where the contractor didn't back their work. I am so glad for you Josh, that I misunderstood the title and these folks backed their work. This is refreshing to see!
Trowel in bleed water causes scaling. Worse yet if you had frost/freezing.
I had that issue before.
It was blamed on the air entrained concrete and that concrete should have been ordered without air entrained
I was a concrete truck driver for 13 years, it was too wet
A stand up guy right there. You picked a good one Josh! Wooooo!
The leaves are off of the trees. It looks cold there. And the temperatures go down at night. I read one guys post saying that there wasn't any rebar. In the long run; it will eventually all fail without the rebar.
i drove a crete truck for over 3yrs and never saw that happen
Ouch... After reading through the comments I hope what they are reflecting isn't true, would be heartbreaking. Good luck.
Too much cream on the top or Butter, Its caused by too much water left on the top. Like you said water pocket with concrete butter. Thats cool he's fixing it
Hello 👋
Glad you had someone that cared about the work they did and the workmanship they did we had a 30 by 50 put up and they put the concrete in and cut it in 10 foot squares and it was supposed have wire in it but after 6 months the hole 10 foot slabs started heaving and moving up and down I called the contractor and he told me for the money we paid we got exactly what we ordered they never did nothing about it we ate the money so very glad you are getting a good concert floor love your channel ❤
Good thing he stands behind his work.
I would say a combination of too much water in the mix and over working concrete to try to get a perfect Finnish. It is just something that happens sometimes!! But if your contractor is Making it right you hired the right guy!
Over troweling can cause that to happen, brings up to much of the finer materials and causes separation.
Hi this is Tom Haus from Concrete with a Hauses one of my viewers asked me to watch your video and give a comment. After watching the video and saw it was power troweled.I feel there is too much air in the concrete there should be low air or no air when power trailing a floor. The surface will start the blister and delaminate exactly what you are showing us. A simple test is to take a golf ball and walk around the slab bouncing it and listen for that hollow sound under the surface of the concrete you’ll know when you hear it. A better test would be a petrographic test unfortunately there about $800-$1200.if you could check with the supplier to see what type of air entrainment was in the concrete that would tell you a lot.if I’m any help that’s my intention if you would like to talk further email the office
great tip thanks buddy!
Tom, you're saying they basically burned the surface by power troweling ??? Tom, do you think that it could be the plants fault for adding to much fly-ash ???
We had a large amount of concrete poured that had issues with spalling. The issue was the plant ran the batches wet that summer and we had intense heat. The two factors caused the cream to come to the top, and the water evaporated out leaving an uneven cure. That resulted in the top chipping off and exposing the rough aggregate underneath.
We built a Garage Bigger then this and the floor did the same thing. It was not the contractors fault that did this it was the mix got messed up at the plant. If you take a test of the concrete and send it in every time you pour, this will allow you to know ( if there is a problem) where in the process it is. We had to take out the floor and the Plant footed the bill and made it right.
hi there i found it really does no mater weather it is . a contractor or my self . when something big (or small) goes wrong or happens it seems to take a bit of your heart . been there to many times , it just makes a new plan start . looks like you worked threw it well . hope for smoother sailing john
Cutting concrete with no water and no mask, love to see it
just had a 25 x 40 pad run for a shop with a 10ftout for a breezeway between another shed my rebar is about 3 ft apart wire tied and i am Not planing on putting heavy equipment on it !! I too am concerend that if didnt see full rebar runs across the cut out areas!!! my slab cost me 7500 just to give an idea of the costs of concrete!!!
your pad won't be in a climate controlled shop though? Frost heave would be the only concern...but we have footings and we have rebar in several places
Open air slab vs basement slab is a huge difference. You need the right weather for the next few days.
I had to plane 1/2" off a slab in a court house. The concrete looked the same. If you hit it with a hammer It would sound hollow. I was told they burned the concrete with the power trowel. Running the planner over the entire second floor.
There is no substitute for quality and the man who stands behind it. Onward!
You should take a small hammer and gently tap on that slab in a grid pattern. Anywhere the surface is separating will sound very different from solid concrete. You can even drag a rod across it and listen. It will make a kind of ssssssskskskskssss sound when you hit a loose spot.
Never underestimate the power of having a RUclips channel 💪👊
Just what I was thinking. Bro. Larry couldn’t afford to have those 640,000 subscribers know he didn’t make it right. He’s probably an honest guy either way.
Larry looks like a Marine. I'm proud that he has my last name. Josh, I am an Air Force Vet also. I was a 46150 Munitions Specialist. Served on Okinawa 1948-59. Veterans helping Veterans, it don't get any better Woooooo!!!
It's cool...some veterans are slime bags too..def don't use past service as a judgment of character lol.
I've have yet to meet a concrete guy I was too impressed with.
I though that that pour was too Big Josh, I think it should have been done in small section. I'm glad they came back for you. Good thing you have this a You Tube Channel. I think the cream as they call it had too much water and maybe they did not work it enough. I would have installed fiberglass strains to the mix and rebar and heavy wire, Josh. I you park heavy equipment in there over time you might get more cracks. I had a Cement company use fly ash in there mix and it caused spalling. They use fly ash as a filler added to the concrete.
man...these guys pour walmart floors buddy...the pour wasnt too big...just had something go wrong with the mix
Water cement ratio , I’m guessing it was pumped and often if the pump plugs or to much fall aggregates separate along with the water . There’s a 100 ways to screw up a slab and I’ve done 101
That happened to me, it was setting up too fast and I'd added too much water to try and fix it, but then I didn't know what I was doing
People like Larry are few and far between.... They are worth their weight in gold !!!!! Way to go Larry...
Was it windy or low temperature or both when you poured? There are serious considerations.
Look for:
ACI 306R-16: Guide to Cold Weather Concreting
I agree with u josh s. Looks like they got a little behind finishing it and if they did squirt water on the surface when they were finishing creates a bad bond at the top quarter inch or so.
A friend who was an electrical contractor always says to double your price do half of the work but to make damn sure you did great work because people will forget high price a whole lot faster than they will shoddy work.
That is always a problem with power floating just run a wide float over when it just going off and that will do over working concrete it can go wrong top contractor standing by his work nice one he is a keeper:))
That's a Marine for ya. We take pride in everything we do and have integrity. Instilled in us the day you get to Paris Island for the rest of your life. . Semper Fi Larry👍
Good Day, I used to own my own business as a Concrete Contractor for 17 years, & gave it up after the 08’ economy down fall, but still dabble in it ever so often, actually getting ready to build my own Shop not as big as the mega shop, but congrats on the new building, but as far as my experience is that those flaky areas thru out the slab is caused by to much air in the mud as an interior mix. What was it the contractor told you?
We had a section of concrete floor do the same thing. My dad should have torn the whole floor up.
That’s a relief. When I first read the title of the video, I thought they had screwed you over. Glad they are doing the right thing.
I wish that he would learn the difference between another and any other. It's a misleading title but for how many times he repeats it in the dialogue I really wonder if he understands the difference in meanings. That could lead to some pretty poor miscommunication situations.
Not knowing more it’s hard to make the assessm really what happened. How much fly ash? How much air entrainment? Weather conditions?
the cap was burned. I've seen this several times by overworking the finish. I bet they put on the power trowel at least 3 time ( or the ride on) . also looks like they used the pans on the bottom and this will seperate the cap as well. Spraying on extra water after the concrete was set will do this. I won't let a power trowel on three time I prefer a wacky trowel.
To me it looks like the blistering on the concrete is caused buy Power trolling air entrained concrete you have to be careful how you power troll air entrained concrete to avoid blistering that's my opinion
just getting ready to start our metal barn (smaller) and enjoying the series
It looks like it froze. Did they cover with blankets? I still think that 70k was a little pricy to form and pour but like I commented before I don’t know the prices in your area. Awesome that they stood behind there work. I’m a general contractor started in concrete and Red Iron buildings. That’s someone who backs there work.
Yup! $70K was way over priced for a concrete slab with no rebar. I did a 25'x28' 6" slab with rebar, that was about $6.5K last year. $70K would be a great deal if it includes the cost of the pad & building.
@@guytech7310 Stoneys is 7 or 8 times that size plus bidens inflation cost ?
@@ky.gambler5281 I don't think so. I think he way over paid for that slab.
Several different reasons this could have happened.. from the mixture at the plant to added water etc… main thing is like you said he made it right!… also possibility of it cracking in different places off of the expansion joints.. another common problem.. good contractor though for coming back and making it right!
Hi josh to much air in the mix my neighbor has a new slab 50 x 60 the whole slab did that. concrete won't do a thing about it. then I plowed the slab this winter and I was plowing the whole top layer off
That's above and beyond on the contractors part. Great customer service.
Great to have a Contractor to stand behind his work. Have a Safe Day
Another thing that can cause this problem is if they tried to finish it too early- before the bleed water came off. On a large slab, you can get different sections that cure faster than others, and some that set up more slowly. Anything that will cause excess water on the surface of the slab will weaken the mix there and cause spalling later.
Dammm... Crazy, I was looking for the follow-up on this pour, and here it is in my feed. Glad you have a solid guy, tho. I do see problems without having rebar in that big of a pour. I recommend you get some independent tests done and see if this is a plant problem. Also, going forward on pours of this size you should have a test company on-site checking each truck. Definitely add the rebar. We would of used #4 or #5 12 inches on center. Good Luck
Thank you both for your service God bless
I am with you , much respect for someone standing behind his work.
Too much water in the mix. Eventually those spalling spots would spread to the majority of the floor.
I'm saying. I wouldn't trust that whole pour
Isn't it a shame that the old normalcy of a man having integrity and standing by his word and his work is a thing to be honored and praised now.
honesty should always be praised my friend....and dishonesty should be announced
@@StoneyRidgeFarmer no you're right, but 19 years ago when I joined the military, it was just expected that you do the best you can and going above and beyond was the norm.

Hi Josh, I’m no expert in concrete but if it was me, I would be concerned that other areas of the concrete might rear its ugly head with spalling. I would hate for your building erector to put up the building and then shortly afterwards, you notice more spalling in other areas.

I agree with Dennis Concrete is my life too. No sense issuing blame, honestly, this happens quite often, pump operator could have added too much water, the plant could have messed up that truck's batch the contractor could have, u know. Mistakes happen and yes, you do have yourself an A+ contractor. A good honest contractor is like gold you hang on to em, congrats on the mega shop! I'm Impressed! Congrats and atta boi, to your contractor for being solid like that and owning the responsibility.
Curious why you do not put a pit and so you could change oil and work underneath a vehicle standing up. That would’ve been really handy very handy .
because I'm putting in a couple lifts buddy...a pit is a water entrapment area around here
Thats from using water to finish cement. They weekend the mix and it got cold. They should have should used chemicals instead of water. Then they should have used heaters and cover with concrete blankets
I would say too much sir in the mix ...then it peels when troweyed..than you put water on while trowling and it doesn't bond...then the frosty and freezing cause this isdue
Local machine shop was getting a new CNC horizontal mill and the 3’ thick footing that was 10’ below grade had to be busted up and re poured with an excavator in the middle of their shop because when the tech came to install the machine he dropped a leveling pad and didn’t like the way it sounded when it hit the concrete. Sure enough when they cored and tested the sample the concrete was not the right grade. Concrete contractor replaced it all on his dime.
if concrete mix didn't have "air entrainment" added to mix prior to pouring this will sometimes happen to surface if water lays on it and it freezes. Adding low air in the batch helps with this here in ohio till winter is over. But hard to get a nice slick finish with air added to mix. It likes to peel finish as they are finishing slab if they stop the trowel machine for a second. Nice they backed up their work! Slab looked great
It looks like spalling, maybe it was poured when too cold, no plastic cover for protection?
Spraying water on the top of the slab and worked it in. Other parts of the slab may do it eventually.
I have worked with several contractors.I have had my share of seeing bad work . I we’ll do my own work b4 I pay someone else to do it .I’m building my own log house now and it’s taken way to long to get it all done but at least I know it we’ll be right
First thing I noticed is that the repour mix had a lot less water in it. Those working the mud prefer very wet. Engineers prefer very stiff.....
Had rebar in too, first pour didn't
Thx for the post josh
Hats off to Larry,,hard to find contractors that stand behind their work and dealing with it so fast
