We're going to have a layer of concrete on the terrace above the garage, but also on the garage floor. It's very bad cement, irregular, and letting loose stones and sand.
The garage has separate electrics, and grounding. Engineer Jansen prefers not to have all that embedded in concrete, so he tied the incoming wire up with some rope, and encased the earth pin in a plastic tube.
The earth pin had two wires, hardly connected to it, as the screw was loose. One wire goes to the copper water pipe (good), the other went into the wall. Not far though, I could pull it out just like that (bad). Properly tinned the proper ground wire, cleaned the screw, and put back in place. I guess the same guy as always is responsible for this "ground", too.
Tomorrow the concrete will be poured.
