Decks, Patios, Porches and Docks - 2nd story deck solid surface

smelling gas when furnce start up help

I am in the planning stage of building an 8'x20' second story deck. The deck has a southern exposure and is also subject to snow and rain. Beneath this deck there is a patio.

I am also looking for a good solid surface to prevent water dripping through onto the porch below. I have looked at vinyl decking, tar undercoats and this is not our first choice. I do like the patterned concrete that you can add colors to.

My plan is to topcoat the deck with 4" of concrete (on top of a poly liner).

Any comments or alternative suggestions?

Check with local authorities regarding building code requirements, restrictions, inspections, and permits.
