I need to remove the foundation from a cinder block home and remove bushes as well. The home was build in the late 70's and I do not know if there is any rebar in the foundation. My original plan was to rent a mini-EX and a skid steer with a jack-hammer attachment to break up the foundation. I had someone suggest to me to just rent the skid steer and jack hammer attachment as it could do to all the work and I can save on renting. Is is good advice or do I need both pieces of equipment?
