Rick,
In my case I used a sledge hammer and a large break bar. i screwed the anchor
in as far as possible, hit it with the sledge and turned it again. I proceeded
that way until the anchor was in deep enough. Each anchor took about 15 minutes
(manual labor).

Thanks for posting that website. Lots of stuff to choose from.
Could you point us to the actual "8" MILSPEC" part you used?
You mention using a jack hammer to drive it. Are you referring
to the arrow head type? AKA "duck bill". As opposed to screw in; I
don't know how you use a jackhammer to install a screw in type.
BTW, please, make and model of jackhammer and bit used.
Here we have not just hard pan, but cemented hard pan, however
zero rocks.
