Best solution is to remove the cobbles and sand and put in concrete base, the method you're doing is not great, it's a mess tbh. It's not practical at all. Tbh I'm not interested in doing it, it's impossible to get it level/sturdy.
You said that you were short of cement. Where did you put the cement? Under the flagstones/on the cobbles?
Putting flagstone on cobbles is a bad idea, the flagstones are uneven because the cobbles are uneven. Builder advice is a joke. The best thing is to remove the cobbles and put flagstones down. Also is it timber or steel shed?
@Paul M. Hi Paul, sizes on photos, plus I would the missus wants the internal house painted. If it suites.
@Paul M. Hi Paul, I have put photos up now. Basically most of base in, but lose on outer edge at back, builder said easier to add a layer to front as back has a slight slope, short on cement on first day.8' x 10' steel shed. Have sheets of 8x4 ply x 3. Plus 2" x 2" battens. My mate keeps letting me down on this. Finish base 2-hrs max, plus do the internal work when shed installed by shed fitters. Im in Ballymun, if you want to view before making decision. No problem. Open to any suggestions you might have on insulation, shelves, work top, after viewing.
How many loose flags?
Thomas what is the size of the shed? Have you got new shelves?
