The Duradek membrane serves a dual purpose by not only safeguarding the deck itself but also providing essential protection for the patio area directly beneath it. By forming a reliable waterproof barrier, it prevents rain and moisture from seeping through, which helps keep the patio area below dry and free from water damage, mold, and grime buildup. This setup makes both the deck and the patio more enjoyable and functional, as each area stays cleaner and requires far less maintenance over time. The Duradek membrane allows homeowners to maximize the usability of their outdoor spaces, creating a comfortable, low-maintenance environment perfect for relaxation and entertaining throughout the seasons.
