If you really can't get anything else to stick try a ultra rapid set concrete llike Emco15. Pack it into freezer bags tied off, place underwater at area to be patched and pierce. mix water in and place over area. Wear gloves as it gets hot enough to burn even underwater (voice of experience).
Denso tape would be another last resort option. Would stick via greasiness and repeal water via same but I'd rather be covered in emco than work with that stuff again.
