Waterproofing a-- soon to be built-- Deck
I have started work on my new 60'x app. 14' Deck. I plan to seal (waterproof) the underside of the deck boards.
I don't really know what to call this type deck constructions and I would like some suggestions and ideas.
I want a nice looking deck that I can place lawnmower, utility trailer, and other items under without a water problem.
I owned a home, a few years ago, that I mounted clear fiberglass roofing to the underside of the floor joist and allowed slope for drainage. It worked very well but was not attractive.
Any suggestions would be appreciated.:)

Would think that would be similiar to seeing the balconies on homes. If you want it to be a bit more attractive, build it down at the bottom, incorporate it together such as a roof, and be able to have the proper drain, even a gutter, and go from there. Is how I have done it with Balconies anyways.

The deck should be built to minimum Code, the waterproof roof inspected at that time;

Be sure to leave egress for any basement windows...

I've seen products like this! Try googling 'under deck drainage system' for some choices.
