I’m planning on laying a concrete base for 2 sheds in the garden, a total area of 17m2. Was planning a depth of 100mm of type 1 MOT, then 100mm of concrete. Can anyone help with how much type 1, ballast and how many 25kg bags of cement I’ll need?
I’ve tried 3 online calculators and getting nowhere (one said I need 13.4 tonnes of type 1 MOT!!!) what am I doing wrong..
