“ One of the easiest ways to add value and function to any outdoor area is to create usable, dry storage space beneath a deck. TREX GO BELOW: UTILIZING UNDER-DECK AREAS For years, homeowners – not to mention architects, builders and contractors – have neglected to take advantage of under-deck spaces. And, for those that have used the space under a deck for storage, odds are it hasn’t been pretty – especially in light of our often wet and rainy U.K. climate. I’ve certainly seen my share of outdoor storage spaces filled with deteriorating items covered in mud, mould and mildew due to being exposed to too much moisture. Still, creating useable space beneath a deck is one of my favourite add-ons to any garden project. The secret to success and customer satisfaction is adding a deck drainage system. Using a network of troughs and downspouts, these systems capture and divert water away from a deck, not only preserving the studwork but also making the area under the deck useable for storage or as additional living area. There are two main categories of drainage systems available, depending on whether they’re installed above or below the joists. For optimal protection and aesthetics, I prefer an above-thejoist system, such as Trex® RainEscape®. This system uses an ultra-durable, rubberized membrane that drapes down into each Above, Trex RainEscape installed. joist bay. The membrane pieces are shaped so that they can be stapled to the top of the joists yet hang lower at one end of the bay to facilitate drainage. When the joists cantilever past a bearer, separate pieces are installed on each side and sloped to direct water to a gutter on the inner face of the beam. PAGE 71 - ARCHETECH
