Create A Waterproof Dry Space Under a Deck

Under Cover System in Louisville


The spaces between decking boards on outdoor decks serve an important function—namely, drainage. They help to prevent puddles from forming and enable the surface to dry more quickly after rain and snowstorms.

Along with routine waterproofing application, spacing between boards helps to prolong the useful life of the decking material. But if you want to use the space beneath a deck for additional outdoor living or storage space, it’s better to install a barrier that prevents water from draining to the surface directly below. Unfortunately a typical gutter and downspout installation around a deck will not get it done.

Undercover Systems

If you have an underdeck ceiling system from Undercover Systems then you are already set. It comes with one of the best engineered drainage systems available and it looks beautiful.

First, a structurally engineered load bearing gutter system is attached using #8 galvanized screws and 3/16 “Tapcon” fasteners to the inside perimeter of the area being covered. The clean looking stream lined gutter system is attached along the house, the sides, and front of the deck. Since we don’t attach our system to the floor joists of deck we often must install wood to the sides and front of the deck under the rim joist. This gives us adequate area to attach the gutter system below the existing deck’s floor joists and provides plenty of air flow and ventilation for quick drying. Gutter bracket supports are installed 24” on center when required.

No part of this system attaches to the underside of the deck. All installation work is done below the existing deck and deck boards. We maintain a 4 inch to 7 inch space between the bottom of the deck and the top of our ceiling. This assures that this product will not cause any harm to the deck above.

After sealing the top edge of the gutter system so no water gets behind we begin installation of the ceiling panels. Starting at one end, our installers begin placing the interlocking pre cut panels on top of the gutter system one after the other. Once all ceiling panels are in, installers clean up job site and you can begin enjoying your beautiful new outdoor living area.
