I did some work for Southern Bell back in the day driving well casing in a triangle around the substations for grounding. Until the engineer was satisfied with the megger readings. 200 feet deep in cases. In Florida.
Drilling into the walls of the nuke/hurricane proof walls sure heated up a carbide bit. A good place to hole out during a shtf situation. While I was one site an Airgas truck showed with liquid N2 to top off the tank inside.
Some years ago I had a loop of direct burial pots cable. Yup. Not only lead sheathed under the plastic jacket.
I found out also that the goo inside is very very nasty if you happen to get it on your fingers and touch your mouth.
Critter proofing. yuck!
