Update
So I have been scanning the site and looking for something similar, I found that there is Quikrete anchorning that can be used on railings. However from what I read this seems to be used primarly when mounting to outside cencerete stairs and would be from the ground up, since I have to mount this from the wall out this does not sound like the method.
I also located information on concrete expansion anchors, what I wondering is one from the looks of the hole, which is two clean holes about the size of a quarter. The expansion anchros look to be smaller then the hole itself, I am sure there are larger if this is the right tool for the job. However the hole for the screw that attaches the raling to the wall is smaller then the exansion anchors. Is there a way to attach the railing to the anchors, drill out the hole on the railing mount? Is there another way to do this? Would I be better off patching the concerete and starting fresh? Any help would be great.
