TOPSIDE® Under Deck Drainage System

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. This provides the ultimate in deck drainage systems.

TESTIMONIALS

The product went in great and is performing as promised.Thank you for all your help and feedback on my first install. A great product with a great warranty. I will be a repeat customer as often as I am able.

AARON EMERSON, CONTRACTOR

We got all the material stapled down and it snowed over 4 inches one night (that’s a lot for us here in Louisiana) before we started the decking portion of the project. Even with all that weight, the staples held the material in place. Got the boards down, it rained over a inch Monday and not a single leak. Everyone was very satisfied.

SHAYNE, CONTRACTOR

I recently installed your product for a client and they love it. I enjoyed installing it and it was profitable.

JASON HARKNESS, BUILDER

Thanks for your understanding and assistance with my DEK Drain project. Your solution of adding 2″x2″ to extend the drop bracing worked perfectly. We are looking forward to spending time underneath our new dry deck! It’s quite beautiful. Everyone that sees it is amazed at how it is engineered and how great it looks!
