I have an old Rohn 25 base in concrete that I want to
get rid of. Can I just pour this stuff down the inside of
the tower legs? What prevents it from just squiring out
the top and not doing anything? Is there any danger of the stuff exploding?
The base is mostly underground of course, but goes a few
inches above ground. Where do I buy the stuff?
