I have to cut into a 4" thick basement slab at about 2-3 inches from the entire perimeter to remove and reset a drainage conduit system (Cactus Board) that was installed upside down ! I have heard on more than one occasion that silica dust is a dangerous carcinogen so I have ruled out jack hammering and dry cutting as options for the removal. I also am concerned that the amount of dust created by a dry cutting diamond blade would harm the electric motor and other moving parts of my HVAC system. Sheet rock dust is bad enough, but concrete dust is just as invidious. Am I correct in my assumptions?
