Ground rods to NOT have to be driven VERTICALLY DOWNWARD ... just INTO the soil.

Quoting Mat Eshpeter <kk1c@live.com>:


I am finally getting around to putting up my 60' AN Wireless tower on top of a rocky ridge in WV. I rented a Hilti demo hammer and got about 1/3 of my rods in to the ground at least 4' -- but the majority are only 2 or 3 feet deep because of the rocks/ledges. I don't think I have much of a choice other than to cut the rods off and drive the remnants into the ground field and exothermically weld my 20 gauge copper strap to all of these shallow rods. Other than paying big money for a well drilling rig to drill some deep 6" holes and filling them with bentonite (which may not be possible given the slope of the land and the fact that I now have 8 trenches running 75' out from the tower pad) do I have any other practical alternatives?
tnx,Matkk1c
