Concrete is measured and purchased in cubic metres.
Follow these easy steps to work out the volume of concrete required.
Area in square metres = Length (m) x Width (m). Using a typical garage floor as an example:
Area = 10m x 3m = 30m²
This may depend on your excavation, but in any case minimum thickness should be:
| |
Paths |
75mm |
| |
Driveways |
100mm |
| |
Garage Floors |
125mm |
For our example, thickness = 125mm
Read the volume required from this chart.
For our example:
| |
Area |
= 30m² |
| |
Thickness |
= 125mm |
| |
Volume |
= 3.8m³ |
Alternatively,
Volume in cubic metres = 
For our example:
Volume required = 
The nearest available quantity = 3.8m³
It is wise to add a little extra for wastage and variations in depth.
For our example we would order 4.0m³.
