Afternoon all,
I need to lay a small patio as a base for a shed.
I was planning to level the ground, then lay patio slabs for the shed to sit on. My question is: what should I fix the slabs in place with? Dry mix concrete? Some other mix? Nothing at all?
Thanks in advance, Al Reynolds
I used 4/5 to 1 sand/cement.

Why bother with the slabs? Just lay a concrete base.
Because I have to carry all the material up a
45 degree slope and slabs are easier to carry. It also means that if I decide I don't want a shed that: (a) the slabs can be used as a patio, or (b) I can remove the slabs (much more easily than a concrete base).Al
Cheers Mungo,
And did you just lay this as a screed layer and bed the slabs into it? How thick a layer did you use?
Al
The earth was flattened (to a certain definition of flattened - I hate moving earth) and then sand and cement was mixed up on a board in quite rough proportions, hence 4/5:1, piled onto the earth and flattened. It worked out to about 2 inches thick, not a lot really, it's not like it was going to have to bear a great load and they haven't moved. Yet.
You might want to mix up a proper mortar for the edges though, to stop them sliding over.

If you can get it fairly flat, just lay them.
Cheers, that's pretty much what I thought. Al
Sand or nothing at all is pretty effective.
