I have an upper deck similar to the one in the photo. The material the buider used to waterproof the floor has cracked and is leaking. What did you use and how long will it last? »
Suzanna Ivey Design The homeowner decided not to use the upper deck, so the contractor laid rubber sheeting. Later, the homeowner had wished they had built it for upper deck use. Too late now without reinforcing the whole structure for use up top. Sorry I couldn't answer your question.
