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-the-joist system, such as Trex® RainEscape®. This
system uses an ultra-durable, rubberized membrane that
drapes down into each 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.

LIMITLESS POSSIBILITIES

Once protected from the elements, the dry space beneath a
deck can be used for any number of purposes from storing
lawn equipment, gardening tools and patio essentials to
serving as additional living space outfitted with everything
from upholstered furnishings and decorative accessories
to ceiling fans, entertainment components and Trex®
RainEscape® soffit lights. Thanks to the innovative abovethe-joist
application of the Trex RainEscape system, gas
lines and electrical wiring can be run safely and discreetly
between the deck surface and a soffit ceiling.
"The secret to success and customer satisfaction
is adding a deck drainage system."
The main advantage to this type of system is that it protects
the entire substructure and the area beneath the deck
from water damage and deterioration. Trex RainEscape also
includes a heavy-duty waterproof tape that protects joists
and bearers from moisture penetration, helps to hold screws
in place longer and serves as a shield between galvanized
metal and timber. Furthermore, the membrane material
– compared with metal, vinyl or PVC – accommodates a
broader range of ceiling options for homeowners seeking a
finished look.

Among the biggest advantages of Trex RainEscape is that it
is very easy and efficient to install – whether during a new
deck build and when replacing existing deck boards. Any
contractor or DIYer can do it. The entire system includes
just five SKUs – a 40cm and 30cm drainage trough sheet, a
downspout, butyl waterproof caulk and butyl waterproof
tape. Additionally, only three tools – scissors or a utility
knife, a staple gun hammer and a caulk gun – are needed
for installation. Each trough is clearly labeled with staple
markers to expedite the process, which takes no more than
a few hours to complete. And, the system is backed by a 20-
year warranty from Trex® – the world’s #1 decking brand.
