How To Replace A Leaking 2nd Floor Balcony Deck & Make It Bullet Proof? Part 2
Above photo: The nasty part of the job, tearing up the old rotting subfloor, waterproofing material and tile.
In this photo the concrete ballustrade along the edge of the deck has already been removed and the workers are tearing up all the deck materials down to the 2x10 floor joists. As you can see the AdvanTech subfloor has disintegrated and turned into a shredded wheat type material. Although AdvanTech is a great material it did not hold up well in this instance when exposed to water on a longterm basis. I replaced it with 3/4" tongue and groove plywood.

Notice, the flashings and stucco has been removed up the side walls 12". Making sure to leave the house wrap and paper backed lath in tact. This is important as you want to lap the old house wrap and felt over the new materials 2" and maintain the drainage plain. This will keep water from getting behind the stucco then leaking behind the house wrap, felt and flashings.
Have an awesome day!
