Why Burien Homeowners Choose Membrane Decking
Vinyl membrane decking (Duradek, Tufdek, Duralast) creates a fully waterproof walking surface for decks built over garages, basements, or living spaces below. Unlike composite or cedar, membrane forms a continuous water barrier — critical in Seattle's 38-inch annual rainfall when the space beneath the deck must stay dry.
Seattle rain falls at an angle. A 1/4-inch board gap in a composite deck channels water directly onto the structure below — fine if there's nothing down there, catastrophic over a living room or garage. Membrane decking eliminates this variable with a continuous 60-mil vinyl surface that drains to the edge, keeping the space below fully protected year-round.
