Designed specifically for paver or duck-board overlay, Ultra Plazadek from Duradek is a waterproof vinyl sheet membrane designed for roofing applications, such as roof decks and balconies. It is installed by trained applicators, offers a 10-year warranty, and has many options for perimeter details, allowing water to drain to a gutter or drain-and-scupper system. A drainage mat is available to put between the paver and the membrane to allow water to drain while keeping dirt and other contaminants from building up. Plazadek is a model of Duradek Ultra, a 60-mil PVC membrane capable of withstanding pedestrian traffic. duradek.com
