I have a mid-70's built split level. I am remodeling the downstairs bathroom and family room - slab, below grade. While grinding the floor readying it for a self-leveling pour I discovered a crack that encircles the drain for the toilet. It has a slight seepage at a couple of spots where it is cracked. I've found no other leaks so far in the foundation. What is the best way to repair this? Your advise is most appreciated! Thank you.
