Kind of a weird subject but I figured I would give it a try and ask here. I need to break some rock and due to its location a jack hammer is not a great option. I have heard you can core (drill) the rock and then add a Expanding Grout to the hole and will expand & break the rock in 1/2. Well at least that’s the idea
So my questions are. What kind of big a$$ drill does one need? And what kind of bits are you coreing with? How big and how deep do you need to core.
Thanks in advance.
