Hi,
I have to make holes in a solid concrete foundating, for setting in aluminium columns about 250mm deep. The concrete is much deeper, so if I core drill it won't be like going through a wall, I won't come out the other side.
The bottom of the core will still be solid concrete.
How can I make these holes? Do I need to core and then drill many holes and then break it out a bit at a time? Or is there another way?
The columns are 140mm x 60 mm and till go in about 250mm. Once in I will concrete them into the holes, but how can I make the holes???
Please H E L P !
