Hey PJ,
How's it going? You've guessed the right Justin!
I figure I'd let my new Milwaukee hammer drill take a crack at it before
I go the route of renting a tool. I'm sure a $1000 tool will do a lot
better job then one that cost a fraction of that. But it's good to know
all options.
I'm guessing my basement is stone & mortar but they sealed the inside
and outside, so it's only a guess. Based on other houses in the area,
I'd say it's a safe guess.
Thanks!
Justin
