Three simple ways to create waterproof rain escapes
Rain Escapes, the spaces between decking boards on outdoor decks are meant to serve an important function, prevent water lodging in between wooden slides and causing damage to the wood. Eventually, they avert wet patches from forming and enable the surface to dry more quickly after rain and snowstorms.
Deck Sheaths and Downspouts
The foremost key for waterproofing areas below decks is to screen plastic sheaths within joist spaces below decking to form holders. The Trex RainEscape system, is a great example of a sheath-and-downspout system. The Trex RainEscape holders divert runoff to downspouts positioned near the joist header. A length of gutter is attached to the structure just below the downspouts to collect water and lead it away from the protected area.
Many recently introduced under-deck ceiling systems use ridged aluminum or plastic panels designed to catch water that drains through decking and canal it away from the area below.
Under-deck ceiling systems provide an all-in-one drainage and ceiling finish that is particularly suitable for areas beneath a deck that are high enough off the ground to provide a sheltered outdoor living space below. Special framing and moisture-protection measures can provide mounting points for overhead light fixtures and ceiling fans.
Waterproofing Decking Flanges
Simpler than sheath and ceiling systems, waterproof decking flanges are an effective method of canaling rain/snow water. The edges of wood decking boards can be milled with a dado blade, shaper or router to accommodate the flanges.
Whether you use gutters, flanges or an under-deck ceiling, creating additional patio or storage space under your deck can add to your enjoyment and to the functionality of your home.
