Ground rod question
Original poster: "Lau, Gary by way of Terry Fritz <twftesla-at-qwest-dot-net>" <Gary.Lau-at-hp-dot-com>
I'm having some new construction done on my house adjacent to my garage
involving a new foundation, and this presents an opportunity to construct a
better RF ground system than the single 8 foot ground rod I presently use.
The footings are about 5 feet deep, so I was planning on having an "L"
shape of 1/2" copper pipe, 5 feet vertical, down to a horizontal 10 foot
segment laying beside the footing. I also soldered on a 1 foot by 2 foot
sheet of copper roof flashing to the base of the vertical segment.
My question is, would it be better if the horizontal segment were cast
within the concrete footing, 5 feet below the surface grade, or would it be
better to just lay it in the dirt beside the footing before backfilling?
If the latter, would there be a benefit to applying a healthy dose of rock
salt about the pipes prior to backfilling?
Thanks in advance,
