Customer has had a shed base laid (not by me, I turned the job down)
which has turned into a bit of a disaster. Its off level by about an
1" in both directions and the surface looks like a roller coaster for
mice.
They want a metal shed erected on top, but there is no way thats
going to work until the base is sorted.

Initial thoughts are to erect level formwork & top the base with a
little more concrete.

Is it going to bond OK to the exciting base, especially where it
'feathers'.? Would PVA help?

You can't feather concrete - you can lay a sand/cement screed, quite strong,
bout 3:1 sharp sand and yes, unibond will help where it feathers to nothing
