How Much Do I Need?

Use these tables to work out how much you need.

Sand

length (ft) × width (ft) × depth (in) ÷ 265 = tonnes + waste

length (m) × width (m) × depth (m) × 1.6 = tonnes + waste

Gravel

length (ft) × width (ft) × depth (in) ÷ 250 = tonnes + waste

length (m) × width (m) × depth (m) × 1.7 = tonnes + waste

Plastering

One tonne of sand plasters approximately 30m² of wall 20mm thick

How much concrete will I need?

Concrete quantities, like any other measure of volume are calculated by multiplying length x width x depth (or height) and are measured in cubic metres (m3).
For example: If a room measures 3m x 4m and the depth of the concrete floor is to be 100mm, the calculation is 3 x 4 x 0.1 = 1.2m3.

To convert cubic yards to cubic metres - multiply by 0.765
To convert cubic feet to cubic metres - multiply by 0.028
