Marco,

I tried to drive a soft copper water pipe into the ground for a ground
rod and ran into problems at 4 feet. Tough clay sub soil from 2 feet on
down caused the tubing to bend every direction.

I got around this problem by using a steel rod in the center of the soft
copper tubing. I threaded the end of the steel rod and used a nut on the
end for a driving surface, ( also made a good  wire connection later.)
You will need to  use a soft hammer or a sledge with a block of hard
wood when driving the rod into the ground. This will protect the nut and
threads from damage.

Good coling to you,

Cliff
