Rob needs to remove a big 'ol chunk of concrete:
<snip>
Once the tower is gone, the widow really wants to have the concrete base gone
too. My
suggestions of building a deck over it was not an option. I remember you
guys talking about using a jackhammer to remove the top

Rob,
I've thought this thru at times because I'm going to have to do the same thing
when I sell this house down the road a bit.
#1. If the base is real close to the house, a jack hammer may
disturb/crack/rattle/harm the foundation in someway.
#2. IF you go that route, dig the dirt away from the side of the concrete so
that it has some place to "expand" into as the hammer goes down.
#3. I'm currently thinking of scoring the base with a concrete saw as deep as I
can then split it off.
#4. Someone suggested expanding clay in holes. Maybe
#4. OR take a page from stone workers who use the little feather and wedge
things in holes drilled into the "rock". They are placed in the holes and then
hit with a large maul, working back and forth from on to another until the rock
splits.
Good luck with the project.
