Shed Resting Base

[Harv123]

Hi,
I have ordered a 6ft * 6ft shed. I have a concrete base of 6ft * 8ft, surrounded on two sides by gravel, one side with concrete slabs that fence off a garden terrace and the other is the dividing concrete wall / fence property boundary.
My question is what should I rest my shed upon above the concrete base? The shed in question is:

Thanks.

I have an old shed in my garden that sits directly on a concrete slab base and the rain water that gets onto the base has soaked into the wooden batons and the rot has spread into the floor.

When I replace the shed, I'll be raising it up onto bricks (probably mortared in place at strategic intervals), in order that the floor of the shed doesn't come into direct contact with the wet ground.

I’ve fixed roofing felt on the base of every shed I have ever erected; one at my last property is nearly 25 years old & still in service with no rot in the floor; current shed is rather large & is 7 years old.

I sit them on either 600 x 600mm concrete pavers or 300mm reinforced concrete fence gravel boards laid over around 30-50mm of compacted sand, either will work just as well.

bricks topped with felt/dpm in a grid pattern every 16-24" [floor bearers spacings]

wood only rots when its kept at a constant moisture content saturated wont rot dry wont rot just the bit in the middle around at around 25% moisture content
thats why fence posts tend to rot where they go through the earth as below and above that point is at the wrong moisture content

get yourself a 11-13mm thick sheet off osb'sterling board or ply wood on top off the flooring in the main work area as the floors on cheap sheds are carp
