The soil in central Texas is called Caliche with a lot of clay,
CaCO3 & shale. Attempting to drive in a ground rod
yielded only a mushroom on top & blisters on me.
Local tool rental place has concrete bits, but maximum
length of 18 inches. Possibly longer bits are available in
a larger city.
Renting a back hoe is out.
Any suggestions appreciated.

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.
