This is difficult to search for - when you put the words “Grounding Electrode” and “concrete” together, you get UFER.
This is not an UFER. The concrete was poured around the driven grounding electrode. I remember a reference some time ago that this was not acceptable, but maybe I’m incorrectly confusing that it’s not OK if you can’t see the connection.
Is either/both/neither of these scenerios acceptable?
