Anyone know anything about concrete?

I worked for a foundation co for about a year 10x12 isnt that big, but you will probably want a truck, cause thats a lot of mud to mix yourself, unless you do it in seperate areas. We did footings and foundations but the principal is the same.

If so, mix it and the pour the area, i would say in 3 or 4 foot squares, depending how deep it is, float each area smooth, dont "pack it" all the rocks will sink to the bottom. Then mix and pour the next area, and smooth again.

If your using rebar, pour half, then lay the rebar in and pour the other half, unless you are tying it into the form.
