I lived for many years in the Dallas area. The caliche was down about 2
feet and was about a foot thick. I had to dig a hole with a shovel down
to
the caliche, then use a heavy hammer and long chisel to get through the
caliche. Then, backfill and proceed as normal. Don't know what your
configuration would be. Good luck.


Thanks Wayne.
As a last resort I will hack a trench with a pick and lay in the rod
at a shallow angle to the surface. Would this give an adequate
ground ? I could also bond it to an outdoor brass spigot
10 yards away or even to an anchor fence in the other direction.

In my opinion the trench would be ok, but I'll leave that to the experts on
the group.

However, I remember chiseling through the caliche to be annoying, but not
that difficult with the right tools. It can be done with a "shooter" style
shovel, but that is a bit more effort. However, I doubt if you would ever
get a copper rod driven through without some major damage to the rod.
