Just a simple RV pad turned somewhat complicated. The left side of the RV pad is nearly 18″ thick, being on a side hill. We laid 2 tiers of rebar around the footings, and a wire mesh over the pad. Poured this in the morning and had to let it sit for a few hours before we could come back and finish it. The perks of pouring concrete in the winter time! Concrete blankets were laid later that night to keep it warm and cure it properly.
