For a 4" slab, about 72 50 lb bags. Boo. For a pour that big, I would be considering buying sand, aggregate, cement as opposed to premixed. Even better, let a company mix it for you.So just in case I can’t sort out someone to do this for me….can I put down the concrete pad for my shed on my own/with someone if I rent a gas concrete mixer and a float? I can get the mixer into my back yard. I have no idea how many loads I’d have to run to get the pad done. Mixers+float runs about $100 for a day. They rent a concrete vibrator too, is that only for bigger jobs? How many bags of concrete for a 10x8 pad?
I can excavate the soil, move it nearby. Get gravel delivered and I have a manual tamper (or do you need a machine?).
I figured the mixer might be cheaper than getting the stuff delivered and less hassle with moving the concrete to the site. I could also be dead wrong.
I’m happy to pay to get this done but the issue may be timing so…..
Edit: also..Lyndsay…guess what, the shed isn’t back ordered anymore!
Concrete isnt my thing but I have done a few projects with it. I dont think a vibrator would hurt but for slabs i did, we just rodded it with a piece of rebar with acceptable results. The deeper the pour, the more important the vibrator becomes (eg walls).
