    Please help 'cos my brain aches!

    Have dug out about 120mm deep, enough for about a 50mm layer of compacted hardcore/gravel/aggregate and a 30mm layer of sand and cement with 38mm flags.

    Total area is a level 29/30ish square metres, and it'll only ever get summer use, occasional BBQ etc, so no need for more substantial construction.

    Can someone tell me how many bags of each I need to order, as I'm not sure:-
    A) how much a jumbo bag usually holds, and
    B) how much extra I'll need to order to cope with it being wacker'd down.

    I've tried Paving Expert and searching on here but I'm still confused...
     
  2. 2 tonnes of hardcore and 2 tonnes of sharp sand should get you somewhere near mate id also mix cement in with the sharp sand on a dry mix about 10 bags should do

    The dry mix should be 10:1 sand : cement and at that ratio I think 10 bags is probably slightly too much but it's cheap enough, so buy it anyway, what the heck.
