Deck Waterproofing

There are a number of considerations to be thought through before applying tile to an existing deck. After reviewing many of my clients dreams and melding them with reality, tiling an existing deck is usually a mistake. Tile exterior decks must be designed and engineered to handle additional loads, subsurface drainage, mortar beds and tile assemblies. Clearances of 3-4" for the door to be above the tile is essential, otherwise drains on doors can get clogged and water leaks into the interior structure of the house. Tiling an existing deck causes problems with railings, drainage and doors typically. Your tile guy will tell you he can do it, I'm telling you you probably can't. Only one of us is selling you something. Here is an article on tiling decks you should read. https://www.duradek.com/_customelements/uploadedResources/WhitePaperTiledek.pdf

A tile deck has been brought up over here before, I my own self have been trying to figure out how it would work and stay working down the road. In the past we All were thinking plywood/cement board/ tile one guy tried it and posted pictures of the failure,none of my little test decks doing it that way worked real well either. Building it like a shower and using the modified as a shower pan I have thought about but never tried. I have several projects out with modified/stringers/ decking 9 years or so out with no problems. And I know a torchdown will last done corectley on a comerical roof granulated or smooth surface for many years so all I can give you are ideas Dont make the fall center on a main drain that would be installing a leak, dont buy any thing serious at the box stores, if your going to do a tear out anyway frame the fall with cant strips fastened to your rafters and re deck,if you can dont have the posts going thru the roof if they have to be sure all needed flashing is instaled corectley and the posts have solid bearing. I still am coming back to the workers far as the leaks go, the worst thing for a roof is people walking on it x 100 the basic concret guy placing the creet base (dont use stones)the chances of a sharp heal,droped trowel,talking on the cell and droping a pencel then steping on it things like that are just to great to expect something not to happen to even a perfect roof/flashing install. I would come closer to trusting 3'' of light weight creet placed over plywood with flashing all around then using very close tolerance com tile,thin com grout line,instaled with construstion adhesive with several coats of high grade uv sealer.

Hi Sophie, indeed on correctly installing and waterproofing. Architect suggested gaco -- not my preference for look + maintenance. The deck is over living space -- big risk for waterproof over a 3 story home. To the question posed, do you have experience on duradek Tiledek success or fail? Real life? As we all know, there is a difference between the computer and in the field. 2d fails in real life. If not, then it appears, as a designer, this question/answer is out of your expertise. Thanks.
