Exterior Porch Floor Over Basement

pitt's picture

I have a 1920's colonial with a front porch over a full basement. Several years ago I installed a new tongue and groove pine wood floor over the old floor. Unfortunetly the new floor is buckling and heaving and water is leaking into the basement. At this point I expect to have to do a complete tear off of both the old and new floors. What is the best proceedure for installing an exterior water tight floor over the basement?

One of my cousins had the same design...IMHO, it's a really bad architectural detail....she ended up tiling it (read up on current shower construction & expand it into the great outdoors)
One of my Moms' neighbors is doing the same on one of their never ending additons...over a garage, not a basement...next time I'm by in the daylight I'll take a peek, see how they are approaching it....
If you are determined to have wood T&G, basically you tear everything off, build a roof (has to have some pitch and a good waterproof membrane, and a place for the water to weep out), then lay sleepers (2x4 on the flat) on top of the roof and nail the flooring to that....
All-inall, not a great building system except in a pretty arid climate....
