This is a diy concrete foundation we did for a garage. The garage slab was 16' x 24'. You could use this slab foundation for a shed also.
We added a two foot high curb wall to the foundation slab so the exterior could be back filled higher than the slab height.

Wire mesh is the most ineffective slab reinforcements one could use. I removed a slab I placed 30 years ago and almost all of the mesh was rusted and corroded. The only good thing was that it made it easier to demo. Pulling up on the mesh is pointless when the finishers step right into the concrete afterwards, pushing it back down to the ground. The best reinforcement is #4 rebar set at an 18" on-center grid with dobies at 36" on-center; 2" dobies for a 4" slab and 3" dobies for a 6" slab. Also, forget the fiber-mesh, the best crack control is saw cutting the control joint grooves a day or two later at 1/3 of the depth of the slab; 1-3/8" for a 4" slab, and 2" for a 6" slab and dividing up the surface area into a maximum of 7 foot by 7 foot squares. One of the best methods of crack control I can tell you is to take your 2" x 5" margin trowel and push in down into the slab at all joint locations where the control joint meets a structure, drain, form, or at the beginning and the end of the joint. This insures the cracks to follow the joints and gets the saw cut closer to the end of the joint where the saw can't reach. Authored by Steve Milovich GC of 42 years

I have been spring forms for a slab that I’m pouring tomorrow. The home owner did the sub grade himself and it was river rock with maybe three inches of sand over it. It was almost impossible to drive stakes. It took forever. I ended up just driving them held back and using shims to get the forms in place. He also wanted me to use lumber that he cut himself. It was rough cut so no planing. And the edges were not flat. It took a while before I realized why I couldnt get my forms to match my string line. I ended up planing the top edge of all the forms myself.

Hello. Does the course you're selling take into consideration soil type, weather conditions, etc? I am in the Catskills and it gets quite cold in winter (frost depth estimated to be around 50"). The soil is very very rocky, too. Would a simple slab be sufficient or do I need some kind of special considerations?

To everyone commenting on chairs...plastic chairs usually break when people walk on them. Dobies can create voids. Not to mention trying to wheel on chairs or dobies. Pulling up the wire is fine. I have done many tear outs where the wire is on the ground. It was not pulled up. When I pour...I pull it up and double check as I’m pouring by looking at the bar that has not been covered in concrete. Give it an extra yank before I walk back in it to screed. It NEVER sinks all the way to the ground. The aggregate settles underneath it. Usually when you find wire on the ground it’s because people get in a hurry and FORGET TO PULL IT UP. People ask how is this monolithic? The slab has thickened edges that will be below finished grade. Theirs no need for 48” . As others have stated it’s a floating floor...that’s why the walls are on TOP of the slab. He did put in L bars and I’m sure he put them in more than just the corners. You twist the L bar so it becomes a part of the slab. Also, commenters, what kind of strength would tying flimsy wire to the upright or horizontal floor add?? Nothing. I live in Nebraska..48” frost line is not required for a floating slab under 500 square feet. It’s detached and we’re not parking tanks or semis on it. It’s a one story SHED. Sorry to mention a competitor Mike, but watch Dave Odell. The guys a serious professional and NEVER uses chairs or dobies. I’m not sure if people are trying to “show off” with all of the knowledge they have...but a lot of the comments are ridiculous.

@MrAdam100576 Жыл бұрын

Very useful info! 1st question: how much does something like this cost? (Ballpark) and 2: you mentioned Maine and the use of materials in your mix. With that climate zone, does the mix of materials replace having to "tie in" the monolith slab into the Earth below the Frostline? I imagine the Frostline is likely below 48" there. If it was DIY and you didn't have the fancy ingredients, could you also use vertical rebar into the frostline depths? Or would something more substantial be required?

@justame7638 2 жыл бұрын

how long after did you form and pour after pouring the floor?

@dementus420 2 жыл бұрын

Yeah, those lasers are really great. Minimum fiddling required. I tell you, that slab looks more like 8 to 9 inches thick if those are 2×12s. That thing definitely ain't going anywhere. I normally don't put rebar in any slabs with fiber. I just pour them about 4 to 4.5 inches thick and I've never had any problems with them. It's a special case or customer request normally when I do use rebar. I guess it is a good insurance policy though. EDIT: I just heard you say you're in Maine so is that the reason for the rebar, all the freeze/thaw movement going on?

@JaredClarkBoaz Жыл бұрын

They sell what's called a "rebar chair" which is a small plastic piece that you can use to suspend the rebar while pouring, but in the video he says he is pulling up on the mesh as they pour. The guy walking over it while pouring is pushing it right back down though, it would seem.

This kind of the way we build foundations in Romania. The difference is on the edge it goes down in the ground 48" minimum. At the bottom at he trench and at the slab level there are 9 1/2" rebars forming like a cage and becoming two beams (one at the bottom and one at the top. If you would look in the cross section it will be like an I-beam with rebar enforcement at the top and bottom. Then for the slab there is rebar going in both direction 3/8" (10mm) every 4" (100mm). The poor is continuous for the walls and slab.
