Hi
I've been asked by my mother inlaw to remove a concrete foundation which had a wall on it at some stage. The foundation is 10 feet long and 10 inches deep and also 10 inches thick. I've never used a jack hammer before so can someone please tell me how long I should allow for breaking up and removing (not disposing of) the concrete. Is it a very demanding job- as I have an occassional bad back?!
Thanks for any help
Jon
