Over-ordering concrete is one of the most common mistakes on London building sites. You estimate how much you need, add a bit extra just in case, and end up with expensive waste sitting in your wheelbarrow. In a city where skip hire costs a fortune and space is tight, this becomes a real problem.
Our concrete calculator takes the guesswork out of ordering. Punch in your measurements, and it tells you exactly how much concrete you need. No more ordering too much. No more running short halfway through a pour.
Why Getting Quantities Right Matters
Concrete is sold by the cubic metre. Getting your calculation wrong by even a small margin can add significant cost to your project.
| Over-Order Amount | Wasted Money | Disposal Hassle |
|---|---|---|
| 0.5 cubic metres | Moderate cost | Manageable waste |
| 1 cubic metre | Significant cost | Skip hire needed |
| 2+ cubic metres | Major cost | Multiple disposal trips |
The problem gets worse in summer. With more projects happening across London, concrete prices rise and disposal becomes harder. Every cubic metre you waste is money down the drain.
How Our Calculator Works
Using the calculator is simple. You need three measurements:
- Length of your pour area
- Width of your pour area
- Depth (thickness) of concrete required
Enter these figures and the calculator does the maths. It gives you an accurate volume in cubic metres, which is exactly what you need when placing your order.
For more complex shapes, break the area into rectangles and calculate each section separately. Add the results together for your total.
Typical Depths for Common Projects
Not sure how thick your concrete needs to be? Here are some general guidelines:
- Shed bases and light paths: 75mm to 100mm
- Driveways and parking areas: 100mm to 150mm
- Garage floors: 100mm to 150mm
- Foundations: As specified by building control
The Concrete Centre provides helpful guidance on concrete specifications for different applications if you need more technical detail.
