NEED professional advice with pool remodeling. I am covering existing deck with travertine. i have removed existing brick coping. How do i replace the coping with travertine or a similar material that will look good. the new floor level is now higher leaving a gap at the tile line. I have not been able to find any travertine coping products or brick coping that is thick enough. i think we need 3 3/4" thickness approx. we cant be the only ones with this problem. Please help!!!
