I have got to cut a channel 100mm x 100mm around the periphery of my
concrete and stone basement floor to put a drainage channel in. What
tools would the panel recommend?

A sodding good vacuum cleaner :-}


Because the easiest, secound to blasting, is to cut with a disc cutter and
then use a decent breaker, such as a Kango or Hilti TE905.

The other way to evacuate the dust would be to apply positive pressure to
the room and blow out the door using a sodding great big fan.

Good luck.
