How to estimate your concrete needs
To calculate the amount of concrete required, you need three measurements:
- Length — the length of the surface to cover (in metres)
- Width — the width of the surface to cover (in metres)
- Thickness — the desired slab thickness (in centimetres)
The formula is straightforward: Length × Width × Thickness = Volume in m³. We recommend adding 5 to 10% extra concrete to account for spillage and uneven surfaces.
