OUR PRODUCTS
All DEK Drain® products come with a fully transferable lifetime warranty, so you never have to worry about
your investment being washed away.
TOPSIDE®
Designed with new deck construction in mind, our patented Topside® panels are attached to the top of your deck’s joists before any deck boards are fastened to create dry, functional, and hospitable space below. Topside® captures rain that pours through the surface of your deck, while protecting the deck frame against moisture and deterioration. The DEK Drain panels are pre-cut to width and length (one panel for each bay) so there is no waste on your job.

UNDERSIDE®
Protective panels – custom fabricated from a long-lasting, thick rubber membrane material and pre-cut to match your deck’s specific measurements – are attached to the bottom of your deck’s joists, capturing water that slips through the surface boards. Intended for existing decks, our Underside systems are easy to install without the use of sealants or caulk.
UNDERSIDE® RECESSED
Fitted up and into the bays formed between joists, our Underside Recessed system allows users to install a finished ceiling with lighting, fans, and additional electrical accessories under their decks.
