Outdoor living space and ample storage are two of the most sought-after amenities by homeowners and prospective homebuyers. In both cases, the space beneath an elevated deck can offer an ideal solution, provided you can keep it dry. With the addition of an under-deck drainage system, this space can be kept dry and become usable for a multitude of purposes and activities.
Protection from the Elements
Using a network of troughs and downspouts, a deck drainage system captures and diverts water away from a deck to protect the substructure from moisture damage and create dry, usable space underneath. But it’s important to keep in mind that not all drainage systems are created equal.
Above-the-joist systems. For maximum protection and longevity, opt for an ‘above-the-joist’ system with poly or rubberized membranes that drape over the joists to ensure that the joists and beams of the substructure are shielded from moisture penetration. This type of system also helps to hold screws in place longer and acts as a shield between galvanized metal and wood. Compared with metal, vinyl or PVC, a poly or rubberized membrane accommodates a broader range of ceiling options for homeowners seeking a finished aesthetic.
Below the joist systems. Systems that install below the joists leave wood and metal exposed to the elements and more susceptible to water damage and corrosion. This type of system can trap moisture in the core supports of the substructure, especially if there is a ceiling beneath the deck. In warmer months, rising temperatures ‘cook’ the trapped, wet wood and accelerate rotting. Over time, this combination of moisture, heat and lack of ventilation can create a potentially dangerous formula for deterioration.
Limitless Possibilities
Once protected, the dry space beneath a two-story deck can be used like any room inside a house. Homeowners can add electricity, water and gas lines, as well as furniture, lighting, ceiling fans and entertainment components, depending on how they plan to use their new-found space.
For homeowners who like to entertain, suggest adding a fully appointed outdoor kitchen or bar area. For those who prefer an open air retreat, create a cozy patio with plush seating situated around a fire table, or perhaps build a luxurious warming hut around a hot tub. For enhanced comfort, add screens to keep out unwanted critters without shutting out the scenery.
Another popular way to use the space beneath a deck is for storage. Ideal for stowing everything from lawn and garden equipment, pool supplies and off-season patio furniture to bicycles, boats and ATVs, this area can eliminate the need for a freestanding shed and keep the garage from becoming overcrowded.
The possibilities are limitless, and the installation is simple. Trex RainEscape, for instance, is a high quality, affordable, above-the-joist deck drainage system that can be installed using just a stapler, utility knife and caulk. Each trough is clearly labeled with staple markers to expedite the installation process. And, the system is backed by a 20-year warranty.
