AmeriDex 3D Deck Visualizer | Design an Above-Joist Dry-Space Deck

Design your AmeriDex deck in 3D and see the dry space under it before you build. The free AmeriDex Deck Visualizer is built around Dexerdry above-joist drainage, the integrated seal between every board that diverts water at the surface and keeps the space under your deck dry and usable. Choose from seven AmeriDex cellular PVC decking colors, preview board patterns, add railing and lighting, walk beneath the deck to see the protected dry space, and get an instant material estimate. Free, no login, works on mobile. Built in New Jersey by A & M Building Products.

Why design with AmeriDex and Dexerdry above-joist drainage

Most decks let water fall through the boards onto the joists below, which leads to rot from the top down and a wet, unusable area underneath. AmeriDex is different: the Dexerdry seal sits above the joists between every board, so the framing stays protected and the space under your deck stays dry. In the visualizer you can turn on X-Ray mode to see the seal between every board, and use Walk the Deck to stand beneath the deck and look up into the dry space.

AmeriDex Deck Visualizer FAQ

What is the AmeriDex Deck Visualizer?

A free 3D tool for designing a deck built with AmeriDex cellular PVC decking and the Dexerdry above-joist drainage seal. It shows the sealed board seams that keep the space under your deck dry, and it works in your browser with no login and no download.

How does AmeriDex keep the space under a deck dry?

AmeriDex uses Dexerdry, an above-joist drainage seal integrated between every deck board. Water is diverted at the surface before it reaches the joists, so the space under the deck stays dry and usable.

Is the AmeriDex Deck Visualizer free, and do I need an account?

Yes, it is completely free and requires no account or login. It runs in any modern browser on desktop and mobile, and includes an AR walk-through on iOS and Android.

Is AmeriDex a composite deck?

No. AmeriDex is cellular PVC decking, a premium wood-alternative that does not absorb water like wood and will not rot or split like many composite boards. Combined with the Dexerdry above-joist seal, it keeps the space under your deck dry.
