Assuming the base is properly laced with rebar, it seems to me that it
might be just as much work to get it out of the hole fractured as
intact. Either way, you'd either remove it in one piece or have to cut
it up anyway.
By the way, depending upon how brittle the concrete is (or saturated
with moisture), dry ice or liquid nitrogen might be helpful to crack
it. I've been told that it is sometimes used in wells to increase the
density of microfractures in rock surrounding the well shaft.

I need to remove my concrete tower base. I have heard there is a
compound that can be put into holes that have drilled in the concret
that will expand break it apart. Does anyone know what the
solution is and where to find it.
