Water proof a concrete slab roof which serves as a roof-top deck
I am looking for a solution that would add minimum thickness to the slab. The deck is surrounded by a railing which would have to be replaced to meet code if the deck surface is raised too much. Two inches would be OK. The initial thought is a membrane but I would like to have a ceramic or manufactured stone tile surface. Is there a membrane material robust enough to accept these materials applied directly on the membrane? Any suggestions for another finished surface?
