Note: in case of multiple layers of reinforcement, you enter the mean cover.

In Diamonds you define the gross coverage.

• Select the element for which you want to change the cover
• Click on and on the button “Reinforcement”.
  

In ConCrete you define the net coverage.  ConCrete will automatically add 10mm to the coverage.

So if you model a beam with a coverage of 35mm in Diamonds, and you want to model the same beam in ConCrete, you should set the coverage to 25mm. Because ConCrete will automatically add 10mm to the coverage.
