Hi guys, perhaps the following question will get some interesting answeres!! On a huge alteration job done on a house in Tamboerskloof, built against the mountain of solid rock, I need to install an earth electrode. No soft ground at all! I get a beatiful 8 ohm reading on the foundations reebar setup, but unfortunately not acceptable. One of the council inspectors suggest a mound of old disused copper waste imbedded into a concrete slab. Any other suggestions from other members??
