I was preparing my bathroom floor for tile when I ran into crumbled concrete around flange. I repaired the space underneath with thin set and floated the finish in the flange area . The space on one side of the flange is deeper than usual and I didn’t backfill it. Now, second guessing after installing the tile. I m looking for guidance on whether or not I could pour new mortar into void with flange in place. I’m concerned about damage to the tile and if it’s necessary. Would I have to anchor the flange all the way around? Guess I should add My assumption is the thin set wont hold and the flange is not anchored. Thanks IA.
