Pouring A Concrete Slab For A New Garage (30' x 24') Form & Pour

Mike's instructional videos are the best! My wife and I watched them multiple times before pouring our first 10'x12' pads in our building. I couldn't have done it without the excellent instructions and detailed videos. Thanks for the awesome content!

For those people concerned about the lack of chairs under the wire, remember this: These ‘slab on grades’ (SOG) that they’re doing, have complete bearing on compacted soil. If this were an ‘elevated slab’, like a 2nd or 3rd floor etc, the requirement for the top and bottom rebar, are that they only be ¾” from the top of the slab and ¾” from the bottom (2 cm). The reinforcement is most effective the closer you can get it to the top or bottom surface. The course aggregate in the concrete just happens to be screened to ¾” (what a coincidence) so once some of the course agg gets under the wire, it can’t get all the way back down.

[@MikeDayConcrete]

Nice explanation, thanks.

[@Btown605]

For this type of slab why wouldn’t you want the reinforcement in the bottom 1/3 of the slab?

[@psidvicious]

@@Btown605 That’s exactly where it is. A sketch would be helpful to explain the forces going on, but imagine a wooden beam. Draw a vertical row of 3 dots on the face of the beam. One dot ¾” from the top, one ¾” from the bottom and one in the middle. Then one inch horizontally away from those dots, draw 3 more dots spaced exactly the same. Then apply a downward force right between the rows. You would find the top 2 dots get closer together (compression) and the bottom 2 dots spread further apart (tension). These are the same 2 forces that will be applied to this concrete slab. Concrete does very well under compression by itself, so no top reinforcing is required. Concretes Achilles heel is tension, so that’s why the reinforcing is installed at the bottom. Getting back to the beam, you would also notice that the spread between the 2 middle dots stays stationary. Proving that the middle is under neither tension nor compression. That is why engineers never mind holes being drilled thru the middle (to an extent, of course) of beams, joists or slabs. That’s also why you’ll never find very much steel in the middle of a concrete beam or slab. It’s all concentrated at the top and bottom bcz that’s where all the forces are happening. Reinforcing in the middle of a beam or a slab is useless.

[@khavafis]

[@vincentimpriano1020]

Nice job Great tutorial very helpful! me and my two sons are going to try and pour a 21 x 21 garage slab inside 8 inch cinderblock walls with expansion joint all the way around the perimeter. i’m having a little anxiety about it. if there’s any pointers, you can give me that would be a big help.! I think my biggest challenge is I only have the two garage doors entering the garage and a man door on the back of the garage at the end of the side wall! I have poured little sidewalks and a little pads, but nothing more than that, and so I thought I would reach out to a professional to get some good tips and directions on having a a successful pour Thank you, Vincent.

[@8IggiE8]

Hey bud thanks for making the video. I didn't see where they pulled up the wire mesh?🤔

[@patrickthompson389]

Great content, keep it up. Could you add a time stamp to various stages of the pour in future videos, so the working times can be established? Thanks for the education, much appreciated.

[@marlinweekley51]

I was about to ask about the anchor bolts when you mentioned them right at the end. You guys are clearly professional grade. Seen other videos that seemingly know nothing about anchor bolts! The foundation guys gotta have a set of prints. One thing thats apparently not as common any more is setting a course of block around the perimeter to build off of- keeps the plate completely away from any water or shop fluids, etc. Great job - nice crew 👍

[@Austinculver2001]

Hey mike! I have watched countless of your videos and what I haven’t seen is on the power trowel, knowing to start out with the blades pitched or flat and what to look for to know when to change the pitch. I have poured a couple pads and have fiddled with the pitch a little but am not experienced enough to know what I’m looking for when I do it. Thanks for all your wisdom!

[@MikeDayConcrete]

Glad to help!

[@Matt1poontang]

Crank em up when she gets hard ...lower when its soft lol

[@bradhalford5366]

Should there be a footing for the building ?

[@laxvideogeek]

I'm curious, this is a fairly large slab and it is for a detached garage so I'm curious why there are no footers? Although local codes will obviously vary, if you are building walls and a roof, why don't you need footers?

[@alphaomega3173]

What a gravy job man! Looks great. I do commercial jobs and they can be so much work. This looks like a walk in the park for you guys! As some guys say... "Easy Money!". Great video Mike. Keep them coming.

[@andrew5550]

Its surprising how old school it is back east..im assuming its east coast.I been a concrete contractor 42 yrs on the west coast 2 guys would pour this and one guy hand finish it...a lil small for a machine imo..hand rod with a 14' aluminum.I dont see any kickers on the forms either thats different.I worked on crews that had 100 finishers 10 ten man crews just one ten man crew was expected to have 17-20 homes poured a day 6 days a week.It was down to speed and science i dont miss it.We had many pours that were 900-1000 yards at once.Its kind of nice seeing how its done out there main thing is that there having fun.

[@bobducharme4809]

I notice you did not put plastic down before the concrete went in. What would plastic do if anything if you use it? I wish the guy I helped watched this video. We had to pump the concrete on a cold day( about 25 degrees in the morning) the tubes had ice in them clogging up the concrete it took an hour to finally get the tube free. We had many problems but in the end the concrete was setting at the end and difficult to trowel. The concrete had excelerator in it and I’m wondering what was our problem? The slab was 30’ x 20’. Your site was really neat, no crap getting in the way. Thank you for a great video. 👍👍👍

[@paulmontgomery5135]

Yes I poured concrete when I was younger you know as a helper I've helped do walls and and slabs and sidewalks and I just can't remember do I need a special grade of cement for a garage which I'm going to park vehicles in for strength it's 4 in enough can you make 4 inch just as strong as our stronger than a 6 in and when you put your 6x6 steel wire mesh and instead of rebar do you put like a little spacer on it so it'll be like in the center of the cement when it's poured and not laying right on the ground it have more structural significance if about the center of the poor wouldn't it and can you just brush finish that slab you don't have to have it smooth and you sealer and do you need a moisture barrier I hope that's not too many questions please let me know something thank you thank you very much

[@jeffdeluca1153]

Is it not necessary to install a stone base under the slab for expansion? How does the soil not freeze and heave the slab? In Pa, a much warmer climate we are required to use stone base. I'm confused. Thx Mike

Are there any regulations about building a garage slab over an existing sewer line running through the property. For instance adding a garage slab spanning the width of a back yard with the sewer line running out the back of an existing home out under the slab and garage.

Where is the gravel for a strong foundation? Did I miss that part?

[@MikeDayConcrete]

It was gravel under the slab.

[@montepeterson8996]

I always sample the base for a slab to find its stability. If you are pouring next to a house or an area by house that has a ground pitch towards the house you may have some very wet ground which is unstable so i compact in a couple yards of class 5 crushed limestone for a good base. Some soils are naturally good or house was back filled with stable soil a base like a rocky clay and sand. So if you dont see yellow rock it doesnt mean the soil wont suffice.

Hi Mike, very nice and informative videos. Thanks so much! Question: I’m about to prepare a 40x40 feet slab ( under roof) in south Florida. It’s under a new home on stilts, in order to have a cleaner surface for my ground floor. The home has concrete stilts. Each of the stilts has its own concrete foundation below grade. There is about 2 feet of sand that was poured over the foundation. - My question is, can I pour my 4 in concrete directly onto the sand? Of course I’ll be using rebar for stability. - Also, should I divide the surface in several smaller sections, or can I pour it all at once? - Last question, is there any specific concrete if I want a polished final surface? Thanks for your input
