Shed base

[george121212]

Hi going to install a 6x8 keter base over some paving slabs as per pictures.
I have read that the base needs to be perfectly flat.

My slabs are pretty flat but not perfect.
I wonder whether something like this to level it off would be a good idea?

GARDEN SHED BASE GRID 8x8 = FULL ECO KIT 2.5m x 2.5m + HEAVY DUTY MEMBRANE PLASTIC ECO PAVING BASES & DRIVEWAY GRIDS https://www.amazon.co.uk/dp/B017NMZPOS/ref=cm_sw_r_apan_i_0ZFGM8QWNE5NAV4SC23G?_encoding=UTF8&psc=1

Or just to install straight into slabs?

Thanks

That’s plenty flat enough. No need for extra expense.
