I need to put a hole in a basement floor. To save my wife all the dust, I
am going to drill holes with a hammer drill, then break out the concrete.
The hole will be about 30 inches square. Question: How many holes would you
drill around the perimeter? Size of drilled hole? I have a 3/4 in hammer
drill.. How deep do I need to drill the holes. I was thinking of going
right through the slab.
Thank you for your time.
