I've tried most conventional concrete adhesives. If there's a "best" among them, please advise.

    What is concrete face rock? Is it a stone look or is it stone? Do you have a picture?

      I was just talking to my husband about your problem and he suggested that you could try Flex Seal adhesive. He said it can be applied underwater. I'm not sure if it will work, since the moisture is a constant issue, but it may be something you'd want to look into. Good luck.

    Construction adhesive made for concrete, cement, stone in caulk tube. I use it for gluing retaining wall and landscape blocks.
