Skip, The UFER ground has done this for years. The only caveat is that the conductors do not extend through the concrete into the soil. http://en.wikipedia.org/wiki/Ufer_ground http://www.psihq.com/i

Building codes now REQUIRE Ufer grounds in many jurisdictions for new foundations. Codes also REQUIRE that rebar be covered with concrete, usually a minimum of 3" to prevent corrosion ingress along t

Why is that a "reasonable extrapolation"? Copper wire won't corrode, and rust/corrosion is the ONLY reason that codes require rebar to be fully embedded in the concrete. Please explain ... Dave AB7E

Agree that the Ufer wiki entry re "chip and flake" is soft. However, the potential problems with buried copper or copper in concrete are well documented/known issues, so I think the logic holds. I th
