Readymix Concrete Volume Calculator
Use the Readymix Concrete Volume Calculator to calculate the volume of concrete you require for your job. Concrete is supplied by the cubic metre. To determine how much is required, it will be necessary to measure the volume to be concreted by multiplying the surface area by the average depth.
The depth is obtained by placing a straightedge or tight string-line across the top of the formwork and measuring the depth in several places. The average of the measurements is used to calculate the volume.
