Tiledek Waterproofing Membrane


There is nothing like the look of tile or slte on that outdoor deck. But the beauty is soon forgotten when water pours into your home, seemingly through the tile. And then you discover that all the attention on the job was towards the tile with little thought given to proper waterproofing. Rot repair is intrusive and expensive, not to mention the cost of replacing the tile.


This is a common story. There seems to be a lack of understanding within the building community about the proper waterproofing of decks, balconies and roofdecks that are overlaid with porcelain tile, slate or some of the other natural stone finishes. That's where Duradek fits into the picture.

Why Use TileDek             Instead of a Modified Bitumen

Why Use Tiledek?

Duradek has been waterproofing roofdecks since 1974 with PVC sheet membranes that are meant to be walked on. We sell our product only one way – professionally installed by contractors who have completed a training course and who specialize in flat surface waterproofing. Many of those decks have been covered with tile over the years. So it is not much of a stretch for us to redesign our regular Duradek Ultra membrane to come up with an anti-fracture, roofing membrane capable of having tile applied over top – Duradek Ultra Tiledek!

Installed only by trained contractors who specialize in roofdeck and balcony waterproofing.


Duradek has 35 years of roofing/waterproofing experience to draw upon.
