Do i still need a concrete shed base?

Hi,guys. I am going to build a plastic shed. And the garden is already paved with slabs,so it's solid.

Do i still need to build a concrete shed base? Is it unnecessary?

Building The base is aimed at lifting up the shed,to keep the floor dry in a rainy day,as i find out the floor is quite thin. Can you give me some advice,please? Thanks a lot!

"If the floor is solid enough to take weight I suggest you get 6-8 additional slabs, put them on the existing slabs and the shed on top. This provides air flow under the shed. If the base is too flimsy I suggest a thick piece of marine ply, seal it with a water resistant sealant, put the ply on the additional slabs and the shed on the ply. Hope that helps."

"With a plastic shed it’s not really necessary as there’s not a lot of weight buts it’s your own choice"

"No you don’t but I would raise your building up off the ground a little by putting a bearer across each end and two equidistant apart underneath you could use 75mm x75mm timber readily available treated from your fence supply stockist"

"A concrete bass in my eyes is a must do. Ive known of some people use wooden palletes but that rots over time due to our winter months. So yes go with the concrete 100%."

"Yes you will always need a foundation otherwise plastic will sink into the ground and can just rot away crack in bad weather conditions"
