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.

Use an angle grinder to cut level channels, dust it off with a
pressure washer and fill any unevenness with car body filler.
