Working out the volume of materials is simply a process of multiplying the width of the project by the length and the depth. This will tell you how many cubic metres of material you will need. Most materials are delivered by the tonne and the calculator below will give you the approximate tonnage for a range of materials.

Different materials have different weights, concrete for example, is heavier than sand. 

The calculator below can be used to work out the volume once you have  the three dimensions required.


Please use the Gravel calculations below when requiring MOT type 1 scalpings

These calculations are based on the values given in this table

Length (metres)


Width (metres)
Depth (metres)   

Required Tonnage

The chart below can be used to work out the volume once you have taken the three dimensions required.

First measure the width and the length and multiply them together. Then use the chart to see how much you will need for any given depth.
