I began demolition of a bathroom today and ran into an unusual (for me) flooring issue. The floor is tiled and it's set on a 1.5" thick bed of mortar. The mortar was spread directly onto the 2x8 subfloor. I don't see any evidence of wire mesh between the mortar and subfloor.
(Tried to upload a pic, but SE doesn't seem to like iPads...neither do I, but that's what I'm on right now)
What's the best way to break the floor up? It's a smallish bathroom (~70sf), but that's still a lot of concrete. Use a concrete saw and cut the tile/mortar into small pieces and load them out? Maybe an air powered chisel? I've used the latter many times for removing tile, but I'm not at all sure it can handle this material....it's a pretty small chisel.
Also, I don't want to create vibrations that may damage the ceiling below (pop drywall nails, etc.) The house was built in the 50's.
Any ideas are appreciated. Many thanks in advance.
