Check out the crew I got together for this monster pole barn concrete floor pour. There are some real good tricks to show you on pouring concrete at a pitch in this video. Hope you enjoy this video and subscribe if you haven't already.
Great job as always Ron. It is interesting to see floor drains in a garage/shop for I assume trucks. Here in my area, Southern Maine, you can't do that unless you have an elaborate sewer system that is designed to separate the oil from the water but, you can sweep it out the door, go figure. I was taught to keep the reinforcing mesh or rebar in the bottom 1/3 of the slab or pier if only one layer was called for. These were jobs that may or may not have had an engineer's stamp on the plans. I started in construction in 1975 and learned from guys who were pouring concrete in the 50's. I know that now in residential garages and some light commercial slab applications, a lot of concrete guys use fiber in the conc and no wire or rebar. If the sub=grade is prepared right, nothing is going to settle anyway so when the concrete cracks, it ain't going anywhere.
I agree the sub grade is the most important part of a slab. We use wire and fiber and always pull it up. I still catch he'll for the wire every video. I also agree it should be near the bottom 1/3 rd of the slab. That sucks you can't put a drain in a garage.
Wish I could post a video here. My 2 year old got out of bed and came an watched this video with me an kept saying “here comes the mud” he wasn’t even downstairs for that part he just knows your voice 🤣
Concrete cracks where it stretches so on a floor that is the bottom of the slab. The top is in compression and the bottom is in tension so the wire at the bottom keeps it from stretching more. It only takes a little bit of effort to tug it up into place where it will stay because it never goes all the way back down when you walk over it again. If you want to chair it up or put it on dobies then 1" dobies will put it in the lowest third of the slab.
We poured 55 yards of a barn floor just like this 10 days ago on a 40 degree day. Got the 4000 psi concrete from Vitale Robinson with 2% calcium (no steel in our floor), got it all down by 1030am, and by 330pm when we were power troweling it, noticed spider cracks everywhere. Have you ever seen that? What would you think caused that?
I would say the surface was drying too fast. I have seen those micro cracks in stamped concrete before. Never in a power troweled floor. I would be calling Vitalle in case you have a problem down the road.
Now make sure that you do your saw cuts 25% of the depth of a concrete to make sure the relief cut cracks there I go 30% just to make sure I'm a professional concrete cutter for concrete coring company.
@@bondobuilt386 Great job on the concrete! Wow, they (home owners) spent all that money on spray foam insulation and did nothing to stop moisture from coming up through the concrete. A plastic vapor barrier would have been cheap insurance to guard against moisture. They certainly spent a ton of money on this project, so I don't think a few hundred more for some plastic would have been a bank buster. SMH
Floor looks good, but why do you only cut an 1" deep? Floors are supposed to be cut 25% of thickness (unless you are cutting with a soff-cut the day of pour. You guys waited two days?
What do u guys have against chairs under mesh? Instead of trying to keep mesh up , Why not pop a chair under steel ,then u know it is sitting at correct height and definitely of the ground.good job .
@@bondobuilt386 I meant U chair up as the truck is unloading ,instead of using a hook U place chairs under mesh as U are uploading ,I know U can't drive over the chairs ,I have been laying concrete over 30 years,I thought U would of seen chairing while discharging the load ,hooks are not used in Australia as mesh isn't lifted high enough as we want reo sitting higher than half way ,it would not pass by engineer if not on chairs, everything here has to be passed by engineer before pour ,bit different in different countries.
@@bondobuilt386 Nice comment, I don't get this guys that are so particular about the wire mesh. I don't care if you jump up and done the mesh once you pull it up it's not going back down!
Fiber is the only way. That wire mesh is only to make it a pain in the ass when it’s time to tear It out. I have torn out driveways where the mesh was right in the middle on chairs and the slab was cracked and separating like crazy. Just a pain to have to have a cut off wheel grinder and a set of bolt cutters at the ready the whole tear out.
@@bondobuilt386 still having trouble with the wire mesh police 😂 still not every day you get to play in the mud with hoes😉 all the best from the UK bud
