Attempted to auger customer toilet and pulled back roots. Pulled toilet and saw roots growing up between toilet flange and concrete. Ran camera and didn’t see any issues with drains. Recommended to remove tiles around toilet flange to remove rest of the roots and seal large gap between flange and concrete with more concrete to prevent roots from growing back. Was able to chip away tile around toilet flange in order to remove roots and pour concrete in gap to fill gaps. Re set toilet and flushed several times. Everything was draining properly.
