UNDERSIDE®

Ideal for existing decks, custom fabricated panels are attached to the bottom of the joists, capturing water that slips through the surface boards.

UNDERSIDE® RECESSED

Panels are recessed inside the bay area between joists – allowing the bottom of the joists to remain exposed for any ceiling material you choose in the future.

DOG EAR JOIST FLASHING SYSTEM

Homeowners who are not ready to invest in a comprehensive under deck drainage system can still protect their deck’s joists from moisture, while installing the flashing necessary for future upgrades.

More Pliable Than Plastic, More Durable Than Metal

All DEK Drain under deck drainage systems are made from a specially formulated, highly durable rubber membrane material designed to withstand weather, pests, and more. Our systems will never stiffen and crack due to temperature fluctuations. Watertight seals around fasteners won’t expand over time and cause leaks like other leading materials.

Backed by the Industry’s Best Protection

All DEK Drain® products also come with a fully transferable lifetime warranty, so you never have to worry about your investment being washed away.

Protect your deck. Expand your space.
