Level base for shed

Hi folks,

I have an area that I want to put a shed onto, it's all 2x2 slabs but they are all running at an angle.

The area is too large to lift and level it all off. I wanted to know if there were any other ways to make a level base? Picture attached.

One idea I read was to cut high density blocks at the correct angle and one side of the shed sits in angled blocks?

Any thoughts / suggestions on what to do?

You do not say what level you have to make up, it looks about 3" to me. I would use a line of paving stone on the lowest edge, if they are rippled , turn them up side down. Lay them on a thick mortar bed to get the top surface where you want (level wise). Then mix up some fine concrete, 3 parts sharp sand, one part pea shingle and one part cement. Pour this into the missing area once you have primed it with EVA+ water or SBR. This is so the very thin concrete might stick to the old base. Shutter off between your reference levels. Cover with old plastic bags to stop it drying out too quickly.
