Here is what my electrician said about ground  rods:
I have been able to drive ground rods  through anything but solid rock
using a large Bosch roto hammer with a ground  rod driving attachment.
The roto hammer is set on hammer only and the ground  rod attachment
must be used to avoid damage to the roto hammer. The roto  hammer
is the largest Bosch makes and costs about $1,000.00. The  ground
rod driver attachment costs about $70.00. Hope this  helps.
