Hi all
Mum moved house and the garden had a rotten old shed sat on slabs (the massive square 30kg-ish ones) which in turn were sat on a thin layer of mortar, a load of sand, then on top of general soil/stones etc.
Ripped the shed down, removed the slabs (gonna reuse them), and chucked the mortar in the tip. I've dug off most of the sand too so it's now just a mixture of some sand, some soil, and small stones.
I want to stick the slabs back down and whack a new metal shed on top but unsure how best to do the slabs. It doesn't need to win awards but I don't want to do a bodge-job which will subside leaving the door unable to close in 6 months or something.
What would you recommend please? Initial thoughts:
- Tamp the ground down as much as poss with one of those manual whacker things
- Add a membrane of some sort
- Put some appropriate sand down
- Level it off with a rake and a long piece of wood (using a spirit level etc) until I'm happy it's flat
- Stick the slabs back down
But this doesn't work, presumably. Those slabs are bloody heavy so putting them down while retaining a fully flat surface is gonna be tricky. Do I need to look at screeding or something here, or is there a simpler solution I'm missing?
cheers in advance
Matt
