Underdecks were dreamed up by two friends, who were wondering what to do with the space underneath a deck. They wanted the space to be dry and useable for any purpose. It wasn’t long before the interlocking panel was conceived of. This is how the This is how the Undercover Systems Inc. Company was founded, and it opened in Atlanta over twenty years ago.

What is an Underdeck?

The space underneath the deck is where our system is used. This is usually storage space of lawn tools and equipment, and rarely do homeowners use this space as a communal area. When we were younger, I would go to my friend’s house for a visit every now and then. We would sit underneath the deck and talk, sometimes about how we could use this space for different purposes. Of course, this is only if the area could stay dry. I left my friend’s house one day and decided to have a panel system fabricated for it. We tried it out, and it worked! It wasn’t long before we were installing the system for friend and family. We had created a new concept called an “underdeck.” We Began marketing our creation and, in 1995, business really took off. Each year after that we’ve been growing, and now we have licensed dealerships located nationally.

Underdeck Types:

  • Galvanized Steel that is Hot Dipped – Approved by National and State deck codes
  • Vinyl – A DIY product. Isn’t as effective for drying under the deck.
