Levelling For A Shed Base

[severen]

Hi all.
Looking for some advice for a shed build please.

i have a new Keter 4x6 plastic shed, have demolished my rotten wood shed and since that one seemed fine i was hoping the base would be good enough for the new plastic one. The base is paving slabs, which i intend to put some of the plastic shed base tile things you get from Amazon, as it will need raising up a few cm to match some block paving i had done.

the issue is, the slabs are not as level as i hoped, some of them being out of skew by maybe 5~10mm. so, what's the easiest way of levelling this off so i can put the base tiles on them? i was debating a layer of sand but presumably the tiles will just push down into it? i have no concrete skills, or much in the way of DIY skills at all LOL, so the simpler the solution the better.

TIA

I used the round plastic adjustable feet on a wooden frame.
Put shed on that

You could make up a wooden base and level it out with packers. DPC under the timber to repel moisture
