Understanding your calculation
Method, example and limitations
How the calculation works
The embedded concrete estimator calculates volume from the selected shape and dimensions, with any entered waste allowance applied afterward.
Example to check
A rectangular slab 4 m by 3 m by 0.1 m needs 1.2 m³ of concrete before allowance.
Before using the result
An estimate of quantity does not specify concrete strength, reinforcement or structural suitability. Confirm dimensions, site conditions and ordering allowances with the supplier or contractor.
