Hi all,
I need help with anchoring a flange to a hardened concrete floor that's uneven around the base of the drain.
About 5 years ago I made a temporary repair to my neighbors toilet flange.
The old cast iron flange (that was leaded on) was busted in two and I replaced it with a new flange. I don't remember what kind except that it was metalic and was *supposed* to be anchored to the floor with bolts. In my admitted ignorance I did not attach the flange to the floor. I could not bolt it down because the concrete around the waste pipe is busted up and uneven. The drill I used with a masonry bit kept walking due to the unevenness and the fact that this concrete is hardened to the extreme made the drill bit make almost no dent at all. (This is a condominium,btw and the entire slab is one piece. Every unit's downstairs floor is like this. I've tried to drill into my slab with no results. It is VERY hard concrete.)
To compensate for the inability to bolt it I wedged something between the pipe and the metalic flange so it was tight. It has held more-or-less for all this time, but now it's started leaking so it's going to have to be worked on and redone. I'm amazed it lasted as long as it did.
Now, I want to redo this right for my neighbor. The problem with the concrete around the pipe remains. What do I do about that just pour some concrete mix and make it smooth? I know I'll need a hammer drill do penetrate the concrete is there any specific bit I should use on this super hard concrete? And should I use the metalic flange I used before or a plastic one? How would I mate it to cast iron? There's probably only 2" to 4" of pipe from the floor, btw.
Anything else I need to know or tell you all? Please let me know.
Thanks for your help
Henry
