To Calculate Yardage needed for your project enter the Width of Circle and Depth.
Note: you must enter your Depth Key Code Value into the "Circular Calculator" for Correct Calculation.
Example: A contractor is putting in a round pool with a 20 foot wide diameter, the base material that is needed should be 8 inches deep (see Depth Key Code).
