How do I calculate how much concrete I need?

With the Rapid Readymix Concrete Calculator, you can work out how much concrete you need in 2 easy steps.

Rapid Readymix's Piling Calculator - How Much Concrete Do I Need?

Step 1: Measure the dimensions of your site (length, width and depth)

Before you can calculate how much concrete to order, you need to measure the dimensions of your site. By this, we mean the length, width and depth of the space the concrete will be poured into. You can measure the dimensions in metres, centimetres, inches, feet, yards or millimetres. (It’s fine to use different units for each dimension.)

Step 2: Enter the measurements into the Concrete Calculator to see how much concrete you need

Once you have measured the dimensions of your site, the Concrete Calculator will do the maths for you. To use it, open up the Concrete Calculator and select whether the calculation is for a concrete slab, concrete footings or concrete piling. Then simply enter your measurements for the length, width and depth, select the right units, and click ‘Calculate’. You’ll get an instant result in cubic metres (m3), which is the unit we use for all our concrete orders.

What do I do once I’ve calculated my concrete?

If you’ve calculated how much concrete you need, you can now get a quote to see how much it will cost. This will include the cost of the concrete itself, and the cost of delivering it to your site. At Rapid Readymix, we offer you a free quote on your concrete delivery, with no obligation to order. And remember: even when you place an order, it isn’t set in stone. If your requirements change and you need to adjust the volume of concrete you’ve ordered, you can.

What happens if I order the wrong amount?

If you order too much or too little concrete for your project, we can easily adjust your order. When you use Rapid Readymix, you only pay for what you use. This means that, if you order 100m3 and only end up using 70m3, you only pay for 70m3. Why? Because all our concrete is mixed fresh onsite using volumetric mixers, which mix the concrete as it’s being poured. So, there’s no waste if you use less than you ordered – it simply doesn’t get mixed into concrete.
