Im planning to pour 4 concrete footings blocks for an 8'x20' storage container. The only support these containers need is on the corners. They weigh about 5000lbs. What size of footing would be required to adequately support these containers?

I would get some 20" sonotube. Excavate to 8" below frost line or competent bearing,(something that you can't easily push a #4 rebar into.) whichever is deeper. Then take that #4 that you just probed the bottom of the footing with along with some #3 x16" daimeter rings and make a rebar cage for each footing.

Or you could just scrape off the sod and throw down some 4" solids. :laughing:

Why so concerned about a 20" conex? Is this a permanent installation?

Of course you know that we can blame the trade deficit for our over abundance of shipping containers. China keeps shipping stuff over here to WalMart, and we got nothing much to ship back. It doesn't pay to ship empty containers back to China, so many of them stay here. Or so I've been told.
