Not sure if anything is actually needed. It just looks unstable. Power is already run to the shed, so it might be difficult to move and do a full concrete pour. I was thinking of lifting with a car jack and finding a better combination of pavers to remove the wood wedges, but I'm open to any ideas. And it is on a slope, the other end is on pavers on the ground. This stack of pavers was the previous owners attempt at levelling I guess.
I'd probably use a jack and some cribbing to level the shed and support it temporarily between the current "foundations". Then I'd remove those stacks of pavers, dig holes for puring some concrete piers and attach some post anchors to the bottom beam of the shed. Then I'd make some molds to extend the concrete piers up to the bottom of those anchors and pour the concrete. Let the concrete set, remove the temporary cribbing, and done.
The thing is not that big, it doesn't need a concrete pad.
If you just like things looking nice, sure, but good luck moving the concrete pad if you ever want to move the shed.
E: I didn't read his post clearly, posts are not a whole ass pad.
I'm not talking about a pad though? I'm talking about som small piers at the corners and perhaps in the middle of the span. What are you on about?
Your right. I'm sorry. I need to get offline, I'm getting too pissy.
