Shed Base
Richard Evans 19/09/2025 - 9.54 AM
I’m unsure if I need a new shed base as my current plastic shed is sitting on older paving slabs. It’s possibly slightly uneven which makes me think I should get a new base regardless. As I have existing paving slabs would a timber base be suitable or would a concrete base still be the best way to go. Thank you.
Are you a tradesperson and able to answer this question?

If the slabs are generally solid and not crumbling, I’d recommend re-levelling them and then either placing the shed straight back on them, or adding a small timber frame/flooring kit on top for extra stability and airflow.
You probably don’t need to go to the expense of pouring a concrete base unless the slabs are in very poor condition.

Concrete base would be the best way to do it

If the flags aren’t sitting flat it’s an indication that the sub base is of poor quality and your new shed also wont sit even as a bare minimum I’d lift the flags and redo the sub base to make sure the flags are sitting flat and even but a concrete base is always preferable

Concrete bases is the best way forward as Concrete slabs can sink in to the ground and this will keep making the base un level

What would be no good as it would rotten in a period of time as it would get dumped? The best solution would be concrete?
