NJ, travertine coping has some pieces broke off and almost all are hollow. 12 years old, I don't believe mastic was used between deck, also travertine, and travertine coping. Can this be repaired without replacing tile line? Any rec's for someone good in NJ, Ocean County. Willing to move on from the trav coping but if a reinstall is possible using existing coping (6x12) then I would love to do that.
