Exterior Tile Deck Advice with the Construction Specifier

Exterior tile decks can be a tricky subject for even experienced contractors, but for anyone who desires insights on the subject of exterior tile decks, there was a great resource included in the February 2013 issue of the Construction Specifier magazine.

‘Avoiding Leaky Exterior Tile Decks’ written by Duradek president, John Ogilvie, is a detailed article that discusses the waterproofing details that can make the difference between a successful and a failed tile deck project.  Having spent nearly 40 years in the deck waterproofing industry mastering the use of PVC membranes for roof deck waterproofing, John knows a thing or two about waterproofing details and the critical elements that are required to protect a home from the constant influence of moisture or water penetration.


In fact, it was John’s decades of experience with deck and flat roof waterproofing combined with the exterior tile industry’s need for a better waterproofing solution that inspired the creation of Duradek Ultra Tiledek, the under-tile waterproofing membrane.
