PVC decking + integrated drainage
Beautiful decking above.
More living below.
Make more of the space you already have. AmeriDex pairs cellular PVC decking with the Dexerdry seal to direct rain off your deck, helping create a drier space underneath.
For new decks and qualifying re-decks.
How the system works
The difference is
between the boards.
Two components work together at the deck surface. See the connection before choosing your color.

A cellular PVC deck surface
Choose the color that complements your home, with a low-maintenance surface made for outdoor living.
A seal between the boards
The Dexerdry TPE seal fits between compatible board grooves as the decking is installed.
A planned path for rain
With the required pitch, flashing, and installation details, the assembly directs rain toward the deck edge.
Site conditions matter. Follow current installation instructions. Open sides can still admit wind-driven rain; this is not a fully enclosed, weatherproof room.
Think beyond the deck
Your favorite room
might be outside.
A place for long lunches. A shaded spot to unwind. Start with what you want to do underneath, then plan the deck above it.

Good questions.
Clear answers.
Start here, then review the details with your builder.
See system detailsCan I use AmeriDex on an existing deck?
Yes, on a qualifying re-deck where the old boards are removed. Your builder must confirm framing condition, spacing, pitch, flashing, fastening, and the current installation requirements. It cannot be added beneath boards that stay in place.
Does it keep all rain out of the space below?
The correctly installed board-and-seal assembly is designed to direct rain off the deck surface. Wind-driven rain can enter open sides, and perimeter details matter. It is not a fully enclosed, weatherproof room.
How is it different from under-deck drainage?
AmeriDex integrates the drainage function at the deck surface. Other systems use a separate above-joist layer beneath the boards or collect water below the joists. Compare the three approaches to match the system to your project.
Where should I start?
Request physical color samples, sketch your deck dimensions, and ask for a project quote. Your written quote should confirm boards, seals, fasteners, accessories, delivery, and any installation costs.
