Cutting Bluestone footings
Hi all,
New guy here, been reading for a couple of months and picking up lots of handy hints!
I have a Victorian terrace on bluestone footings, very little sub-floor clearance, and little sub-floor ventilation. (Made worse by the concrete slab poured in the rear half of the house)
In an effort to improve the situation I am putting in a sub-floor vent fan, and knocking out a few bricks between rooms (below floor level) to increase air flow. In order for these openings to be below joist level, at some points I need to remove some bluestone - about a 1/2 brick size.
Does anyone have any advice on cutting the bluestone? I was going to try drilling some holes with a hammer drill, then using a chisel or point in the hammer drill. Hoping not to shatter/crack/otherwise disturb the bluestone footing.
Any advice appreciated.
(Note: I'm not cutting the full depth of the footing, just want to remove a slot about 50mm deep x 100mm wide in a reasonably controlled manner)
Thanks in advance...
