How To Form, Pour, And Finish A Concrete Slab (DIY for 2023)

3 роки тому

#EverythingAboutConcrete #TheConcreteUnderground
This video will show you how to form, pour, and finish a concrete slab for 2021. If you're thinking of doing a diy concrete slab, I'll show you how we set the forms properly, how to pour and screed the concrete, how to bull float concrete, and how to mag float and broom finish the concrete.
All you need to know to install a do it yourself concrete slab.
Then if you need more information or more training to install a concrete slab, you can join my private training membership below.
Inside The Concrete Underground I will have some of my very best concrete training videos to teach you how to work with concrete very much like I do.
I also have a concrete slab course below that teaches you all the steps you need to know to install a diy concrete slab by yourself.

If you first attach the two ends of those long 2x6's to the other 2x6's in the corners, you can then join the patch 2x6 in the middle to wherever the two 2x6's end up. No measuring to fit. You are the best concrete professional I've seen in 40 yrs. Great instructor too.

Hi, Mike. I was wondering what I should have done to improve the edging finish on small, exterior slab panels (6' X 42"). There were 6 of them...all tied together. I had to mix bagged concrete (Quikcrete) onsite. There was no access. I used #4 rebar, also. So, all the control joints developed with each panel placed. It was, essentially, all dowelled. Just didn't seem to be able to picture-frame everything as nice as I would have liked. And, I had to wait a long time to do the final edging of each panel (even though I mixed to about a 3-4 inch slump). I vibrated with a pencil, as we went. I bull-floated and mag-floated (when the top water evaporated) We could only get 3 30kg bags in the mixer at a time...18-22 bags per panel. We bent part of the 12" grid bars to come vertically into a 90 degree knee wall to retain previous landscaping on my good old Hossfeld Bender. We built the custom wall forms from 1 X10 pine boards and made all the ties (kinda like Simpson Strong Ties), ourselves. Anyways, should I have added some Portland to each 3 bag dump to get more cream? Just curious. By the way, I'd like to thank you for all that I have learned from you...up here in Ontario, Canada. I'd love to send you some pictures of this little project.

If you’re going to pour and finish with only one guy, I strongly recommend using the Kentucky over under trawl technique… for a one-man show it really speed things up… I was taught that method back in 62 and it has helped me win numerous finishing awards… 10 years ago, I was voted best finisher of the year and would have gone on to nationals if not for my carpal tunnel wrist issue… even today many folks consider me one of the fastest finishers in the west… not bad for 87-year-old man…

Great video! Thanks. Now a question. You mentioned 'cutting' your expansion joints at around 14:55. Does that require a special, maybe wider, concrete blade? Or a kind of router bit for concrete? How deep do you cut? Anyone? Obviously I'm not a pro but I do have a pour coming up.

@uclaalum88 2 роки тому

I’ve always just used a concrete blade in my worm drive Skilsaw. To keep my cut lines straight, I first lay down a straight 2x6 and I tack it down on top of my perimeter form boards. Then I keep the table of my saw on one edge. Lastly, I make sure the depth of my blade isn’t hitting any rebar. You don’t need to go real deep … the idea here is you’re trying to make the concrete crack where you want it to. That’s my .02. But Mike Day would know better than I.

@AncientGains Рік тому

Have you ever poured slabs that will hold heavy equipment? I’m planning to put a car lift on my slab and trying to figure out how much reinforcement to use. More rebar? Deeper slab in that particular spot?

@LarryTait1 2 роки тому

Excellent video as usual. I found the edging tough if you wait a little to long after the pour. A bit of up and down against the form was required to get the cream to come out . How long do you wait for the 4000 psi concrete to harden a bit, or what do you look at to say it is ready to edge?

@devrodriguez2844 2 роки тому

You can start edging after you screed it and bull float just to get the shape and help the stones go down don’t over do it leave it and let the concrete set up . You have to mag before you use your edger once it starts setting up so the stones left over go down you know it’s ready to finish when you can push your finger a half inch down and feel it getting solid but the top is still soft

I have tried looking through all of your videos to see if you have covered my question, but after several, I thought I would just ask. Can you please tell me, basically, do you always finish trowel AFTER magging? Or can you just finish with the mag and then broom? On some of the videos I see just the mag before brooming but then just saw one where you're finishing with a hand trowel. I can provide my email if that would be better for you to respond.

@MatzeMaulwurf 11 місяців тому

Hi, very different from Germany. Here we put a foil (0.2mm) under the rebar on the gravel. This prevents the water in the fresh concrete to drain into the soil. This would change the water/cement value. Next I allways use a vibrator. Really allways. Also if it’s only a very small area. On such a big area for sure. This makes it so much harder. And I would use two part rebar. One 30mm over the ground, than a spacer, than 30mm under the upper side. And use much much more rebar. I would never trust the ground. I always compress it by myself. If it’s not done right (material, thickness, compression) you will get problems. Thanks for showing how it is done in the US.

(new at this) ....what does a water reducer mean in regards to the concrete, pour - leveling - strength - time to dry?

@michoacanohh2227 2 роки тому

Water reducer allows you to have more work time with the concrete without ruining the structual strength it will cure out to.

@randybobandy9828 Рік тому

@michoacanohh no it doesn't give you more work time, it allows you to have a higher slump without compromising the strength of the concrete. Higher slump= more fluid and easier the concrete is to flow and pour. That means less back breaking work in order to try and screed and float it out. The work time is still the same as the concrete will harden by the same point it would without the reducer.

@MuddyfeetConcretePumping 3 роки тому

When you use the water reducer , do you get a lot of water bleeding off? The times I’ve use it , it seemed to bring some trash to the top of the concrete and made the top peal off when you would try and do your final finish with the trowel

@aarongrabowski3775 3 роки тому

When the top peels off like that, it is usually a sign that you are starting to finish too soon. Your closing the surface off before it had enough time to use the water up. When you finish you are sealing up the top off the concrete so it does not set as fast as when you do it with a mag or resin trowel. Those two tools would leave the surface open so that it will still be setting. When you finish too soon, you are sealing up little pockets of water under the surface, which is going to start to blister the surface of the concrete. Little spots that are delaminating. Never rush putting a steel finish on it until you are sure it’s ready.

@aarongrabowski3775 3 роки тому

Hope that helps

@MikeDayConcrete 3 роки тому

No, the water reducer up here means we get less bleed water. And what Aaron said also, he's right on. We also have air-entrainment in out concrete which leads to less bleed water. The tiny air bubbles doesn't let the aggregate settle as much. With no air mixes the aggregate settles and "pushes" more water to the surface.

If you live in a rainy area no need. If it rarely rains where you live its always a good idea to wet the new concrete down in the morning and in the after noon for the 1st 3-5 days it will help reduce the cracking factor.
