Execution

Prior to installation, an examination should be conducted to verify that the existing deck is secure and solid in accordance with local code structural requirements, and that the surface is clean and smooth, free of depressions, waves, and projections, and properly sloped to drains, valleys, and eaves. Any joints, voids or low areas of a wood deck should be filled and sanded smooth. Any surface imperfections or variations on a concrete deck should be filled with leveling compound and the surface cleaned of any contaminants. Waterproof PVC membranes should not be installed when temperatures are below 25 degrees Fahrenheit, above 98 degrees Fahrenheit, or when winds are gusting over 30 mph, and should be installed with the minimum number of seams possible. All seams should overlap by 3/4 inch and be heat-welded.

PVC Membranes-A Option for Outdoor Spaces

Factory engineered to be resistant to fire, UV rays, and mold and mildew, PVC membranes are easy to maintain and available in a variety of colors and textures. Today, they represent a valuable option for an aesthetic means of waterproofing all types of walkable surfaces, including sundecks, patios, balconies, pool surrounds, stairs, porches, balconies, sundecks, and walkways-or any outdoor area requiring a cleanable, waterproof surface. Generally speaking, for roof decks or surfaces requiring maximum protection, heavy-duty sheet flooring is ideal. Lighter weight vinyls, on the other hand, offer cost-conscious solutions for deck and balcony surfaces not exposed to heavy traffic or extreme conditions. Smoother textures offer easy-to-care-for surfaces that are better suited to indoor pool decks, hot tub areas, and even garage floors. Because they can be installed quickly and easily in any weather, even over existing coatings, PVC membranes result in fewer disruptions and lengthy closing of buildings or areas of buildings being covered.

When executed properly, waterproof PVC membranes make a significant contribution to creating outdoor spaces that are livable, attractive, and durable. "The flexibility and simplicity of PVC membranes are great," maintains Robbins. "They offer us peace of mind when specifying this critical type of item."
