Duradek, The Original sheet vinyl membrane for waterproofing decks and balconies, was developed to solve leak problems over 45 years ago.

All Duradek sheet vinyl is designed for strength, stability and slip-resistance. Duradek waterproof vinyl flooring is only installed through a network of Authorized and Trained Installers who ensure the application is done right!

  • Permanent waterproof protection for sundecks, roofdecks, balconies & more
  • Available in many stylish colors, patterns & textures
  • Industry-leading 15 Year Warranty

The old liquid applied and concrete topping products were the only options previously available, and they were failing repeatedly. Property owners and builders complained about leaks, unsightly appearance, expensive repairs and time-consuming maintenance. Duradek recognized the need for waterproofing to be performed by Trained Applicators, and as result, all Duradek Dealers go through an extensive training course – Complete Project Management, LLC is one of those Trained and Authorized Dealers.

I really was led to believe that properly treated wood would be impervious to the weather. Well, I found out it wasn’t, and boy was it a painful experience. Now I know that Duradek is the only guarantee of a maintenance free deck!
