Is it required to pour a footing with a slab in
order to build a 2 car garage. I was going to pour
a 20'x20' 4" thick slab with reinforced rebar and
built a 2"x4" framing with 5/8" plywood sheathing
building to house two antique vehicles.
Can I avoid using a footing or perhaps pour a
thicker slab or concrete? Please advise.
