Garden shed on concrete block

[Goldorak]

Hi,

New member - first post - Hello everyone.

There is a thick and strong concrete base in the garden, on which there used to be a shed, we moved the shed when we moved in.
Now considering putting a new 8x6 shed on the base again THIS ONE

The concrete base is level, however it is rough finish, if that is the correct teminology (like bad skin), with water standing in the troughs that are about 5 ml deep.
I am wondering if that could be an issue with rain water sitting underneath the shed - The base is a about 4 inches wider and 4 inches longer than the shed.
The base is in a corner, along a high wall (south) and a fence (east). So the exposed sides will be north east.

Do i need to worry about potential water sitting underneath? If so, I was thinking maybe slightly spaced out flags between shed and slab. Thoughts?
Also, the shed being slightly smaller that the base, should i position the shed bang in the middle or right along a corner?

Cheers.

Perfect, thanks very much for your help everyone.
@alexakasloth, looking at Skinner's sheds right now - they look good. I'll give them a call.
Cheers all.

I'd drill a few drainage holes through the concrete where the water pools too. Not instead of any of the solutions already posted but just as a backup in case water does get under somehow. A normal hand drill will get through concrete no problem with a masonry drill bit.

Cheers Touch, i have order this to go between shed and base https://www.thegardenrange.co.uk/p/garden-base/shed-base/shed-base-kit-8ft-x-6ft/
Can withstand 420 tons per square meter - this will defo keep base dry.
Cheers.
