Concrete calculator

Work out exactly how much concrete you need for your slab, driveway, footings or posts, in metric or imperial. Then book it in, mixed fresh on site so you only pay for what you use.

How much concrete do you need?

no.
Uneven ground eats concrete. Because we mix on site, you only pay for what you actually use, so it's safe to allow a little extra.

How to measure

01Measure in one unit

Pick metres, feet or any mix: each box has its own unit, so measure however suits you.

02Use the deepest point

For uneven ground, measure depth at a few spots and use the deepest.

03Add a small allowance

A 5 to 10% buffer covers settling and spillage. You only pay for what we pour.

No waste. No part loads.

Our volumetric trucks mix your concrete on site, so if you need a little more or a little less on the day, it’s no problem.
