Water Proof Balcony
I'm trying to construct a balcony/deck over a dry storage space.I want to use redwood decking for the deck surface. The deck boards have spaces and are not a waterproof surface. I want to know how to construct the deck over a water proof plywood floor (with waterproof barrier). What degree of fall should make the plywood surface under the deck ? What's aggod material for the waterproof barrier ? Do I use fur stips under deck boards ?
