Quantities for a concrete bed
I need to lay a concrete bed ready to lay quarry tiles on.
The are is 8ft x 4ft x 4".
Can anyone tell me the calculation for how much ballast and cement?
You need 0.3 cubic metres of concrete.
Length x Width to find area and then x depth to find volume.

you would need around 6.5 cubic meters
