Duradek is an outdoor vinyl flooring system that provides an attractive, finished walking surface and roofgrade waterproofing in a single-ply, single product solution.
Since 1974 over 150 million square feet of Duradek outdoor vinyl flooring has been successfully waterproofing sun decks, balconies, roof decks and more.
