I need to attach a 2x2 gatepost, with a flange at the bottom, to my 4" concrete sidewalk.
What is the best way of bolting the flange (4 holes) to the concrete? I have a 1/2" hammer drill with a 9/16" concrete drill bit.
How do I proceed from here? Can I just drill 4 holes in the concrete with my 9/16 bit and then insert some kind of a fastener in the holes? What kind?
