Tufdek products are specifically designed for use as waterproof walking surfaces on decks, patios, roof decks or wherever an attractive durable waterproof surface is required. The fact these products serve as waterproofing materials makes the installation extremely important. Tufdek membranes must be installed with waterproofing and roofing procedures in mind and should only be installed by Qualified and Certified Tufdek Dealers. The Tufdek system of materials and installation details takes the guess work out of any waterproofing application.
