One small section of our roof's parapet looks like this. We will be installing one 3/8" x 3" havy-duty concrete screw anchor in that area.
The ideal solution is to remove and replace with new concrete. But we can't do that at the moment, so we need to find another way.
That piece of concrete is not loose, but I think it's not strong enough to withstand drilling and screwing in one of these huge screws.
So my question is: is there a product that I can use/pour that will reinforce that piece of concrete to withstand drilling and installing a 3/8" x 3" anchor?
