How much concrete do I need?

To work out how much concrete you need, multiply length × width × thickness. So a floor or foundation that is 5 metres long, 4 metres wide and 10 centimetres thick needs 5 × 4 × 0.10 = 2 m³ of concrete. Always order about 10% extra: concrete settles, and some is left behind in the drum and the hoses. Enter your dimensions below for a quick calculation.

Volume: 2 m³ · including ~10% margin: 2,2 m³

Always allow about 10% extra: concrete settles, and some is left behind in the drum or hoses.
