Duradek – the original sheet vinyl membrane system for waterproofing decks and balconies, was developed to solve leak problems over 45 years ago. It permanently waterproofs decks and balconies better than any of the alternatives – providing both commercial and residential waterproofing solutions. The Duradek System consists of a number of different types of sheet vinyl products, compatible adhesives, and accessories designed for a range of exterior pedestrian deck and flat roof deck surfaces. It is unique in its manufacture and its assortments of patterns, colors and textures. The Duradek system is installed exclusively by trained and authorized applicators like Riverview Development Group who understand how deck waterproofing details play a role in protecting the entire building envelope.
