No problem. We did try with a flat wall tile removal type of chisel + SDS
but it didn't even touch it. The trick is in the tool end - if you think of
a very strong but thin and flexible piece of sheet metal you're on the right
track

I checked with our local hire shop - they have a large Bosch hammer
drill with an almighty big 6" wide 'board-lifter' type of attachment
bolted to the drill shaft. It's not a 'board-lifter' though as it's
fairly flexible. They said that because of the width and the
flexibility it's not likely to break into the concrete.

I'll try it out on Monday and let ya'll know how it went.

Cheers,
