And then there is western hardpan. Two "professional" laborers were able
to drive in two 10' ground rods with sledgehammers in only three-hours
time. Since my planned ground field called for 35 rods, I was looking at
two man weeks of professional labor.
We tried water-drilling (nothing), small electric jack hammers (nothing),
large pneumatic jack hammers (bent the rods) and carbide masonry drills
with 6-foot shafts (bound up).
Now, I know in my heart that the next step would have worked--namely
pneumatic drilling--but I admitted defeat first. I ended up trenching,
flooding and burying fifty-foot lengths of 1-1/2 inch copper strap.
At some point one needs to listen to the Gods when they say "No." :)
