In reply to Slackboot:
I do a few wall demolitions/removals.
The DR concrete panels are great as they can be unbolted and reassembled so usually try to pass these on to people.
Usually fairly heavy though.
The bendcrete walls tend to be fiberglass panels that are joined with fibreglass then concreted over.
They can be cut out in sections and rebuilt but its a lot of work and probably easier to build a new one after time is factored in.
