Afternoon,

I need to lay a concrete base for a shed. I recall needing a mixture of
ballast and cement, but need help in

a) what ratio to mix the cement to ballast
b) how much ballast and cement to order.

The shed size will be 10ft x 6ft.

I'm asuming the base will be around 6 inches deep (unless you guys advise
otherwise).

Thanks,
John
