Picture didn't work. Upload it to a site like photobucket or something and then you can just post the link. Maybe some when else can help without a picture, but I am not sure what exactly you are talking about. Try doing a lot of research on this forum, I'm sure you will find a similar situation.

Yup... my guess is concrete backer board w/ mud to hold it down... it looks like someone laid sheets of the backer board... While it is a water proof board, it is very weak and has little flex - once it breaks it comes apart in chalky-clumps like this picture shows.... Def not a marine product - Just My Guess!!
