PROTECT AND OPTIMISE OUTDOOR SPACE WITH ONE SIMPLE TOOL
Many homeowners don’ t realise that the space below an elevated deck holds tremendous potential. With the simple addition of an under-deck drainage system, this area can be used for almost anything – from storage to additional outdoor living space.
LANDSCAPE & EXTERNAL WORKS
WHAT IS AN UNDER-DECK DRAINAGE SYSTEM?
In most cases, decks are supported by substructures made of timber. When exposed to the outdoor elements, joists and bearers are susceptible to moisture penetration that can lead to mould growth, rot and rust that can accelerate structural deterioration. An under-deck drainage system uses an integrated network of troughs and downspouts to divert water away from a deck. This protects the foundation from moisture penetration and creates dry, usable space beneath the deck surface.
TYPES OF DECK DRAINAGE SYSTEMS
While there are multiple options for under-deck drainage, systems largely fall into two categories: those installed beneath the deck framing, and those that are applied over the joists.
Below-the-joist systems consist of metal or vinyl panels applied to the underside of a deck’ s joists with the panels sloping to a gutter at the deck beam for drainage. A major disadvantage of these systems is they leave wood and metal exposed to the elements and are more susceptible to water damage and corrosion.
the substructure and the deck boards. Using components that are applied on top of the framing, these systems act like shingles on a roof protecting the entirety of the substructure.
Trex ® RainEscape ®, for instance, is an above-thejoist system that is highly effective and backed by a 25-year warranty. The system includes just five SKUs and requires only three tools for installation: a utility knife, staple gun and caulk. Each trough is clearly labeled with staple markers to expedite the process, which takes no more than a few hours to complete, depending on the size of the deck.
ENDLESS POSSIBILITIES
With an above-the-joist deck drainage system, builders and homeowners have the option to add a soffit ceiling for a more finished look, and the space it protects can be used for almost any purpose. Electrical wiring and gas lines can be safely and discreetly run between the deck surface and the ceiling to power lights, ceiling fans, entertainment components, grills, appliances, and more. The possibilities are virtually limitless.
