A waterproof space under your deck.
The uses for the area under your new deck are limited only by your imagination. Turn it into a game room for the kids, storage for lawn and garden equipment, or a second entertaining space with no worries of leaks that are typical with conventional roof decks.
How LockDry Waterproof Decking Works
With LockDry’s unique locking seal, a large majority of water that collects on the deck drains directly off the top. A very small amount of water will seep through the Locking Seal and collect in the Continuous Gutter. With a required slope on the deck, water drains to the outside and off the deck.
The Edge Trim is also used as a drip edge to direct the water coming off the deck to drip straight down. A typical house roof gutter can be used under the edge trim to direct the water where you want.

FAQ's
How do I get product and pricing information?
Directly from us. We sell and ship all products direct to keep cost minimal. Please fill out our contact form for free samples, literature, and pricing.
What information do I need to send for a detailed quote?
We like to get a faxed or emailed drawing from the customer showing the outside dimensions of the deck. This helps eliminate any confusion and allows us to lay out the decking for minimal to no waste. Please print a deck design sheet from the Downloads section of this page to draw your deck on and send to us. Please visit our Contact page for contact information.
What lengths are available?
LockDry decking is available in 12’-2″ – 26’-4″ lengths in 2’ increments. It is available up to 40’ by special order. Wood grain colors are available up to 24’-4″ long.
How is the decking cut and what tools will I need?
Standard woodworking and power tools are all that you need. Most orders only require an electric drill with assorted drills and bits, tape measure, pencil, & a miter saw. For cutting the decking, a blade for non-ferrous materials must be used. Example: Diablo® D0756N – 7 1/4″ 56T Non-Ferrous Metal Cutting Blade or equivalent. Diablo® D1084L – 10″ 84T Non-Ferrous Metal Cutting Blade or equivalent. Diablo® D1296L – 12″ 96T Non-Ferrous Metal Cutting Blade or equivalent. Non-ferrous cutting blades can generally be purchased at local hardware or welding supply stores. We also stock 7 1/4″, 10″ & 12″ blades. Do not use an abrasive cut off wheel.
What are the board sizes?
LockDry decking covers 6″ in width and is 1″ tall. The last board can be cut to width.
Can LockDry be installed directly on joists or plywood?
Yes. The decking can be installed on any standard sub-structure providing there is adequate pitch for drainage. When installing on plywood or a solid structure, the decking can become warmer to the touch without air flow under the decking.
What are the main requirements for my deck framing for LockDry® decking?
Proper slope: The deck framing needs to be sloped in the direction that water needs to drain. The decking also needs to run in the same direction. Minimum 1/8″ per foot slope is required.
Flatness: The framing needs to be flat and true with no major dips, rises, or waves.
How much does LockDry decking weigh?
LockDry is 2 lbs per square foot. About 1/2 the weight of wood and much stronger!
How hot does the surface get in the sun?
LockDry decking stays as cool or cooler than most wood, pvc and composite decks. Our powder-coat finish reflects heat combined with the heat dissipation properties of aluminum. It is recommended to have adequate air flow under the decking for maximum heat dissipation. Darker colors will be warmer than the lighter colors. On very hot days, 95 degrees plus, the decking will be very warm, regardless if its still cooler than alternatives.
How well does it hold up in very hot and cold climates?
LockDry® decking is one of the most durable decking products available. Because of the aluminum construction, it is able to withstand extreme heat and cold. Aluminum has a working temperature of -400 to 400 degrees F. It is completely fire proof and has a melting point over 1200 degrees. LockDry aluminum decks will not freeze and crack because aluminum does not absorb water. They also have very low expansion and contraction characteristics because of the lack of water absorption.
How durable is the powder coat finish?
Powder Coat is one of the strongest and most durable paint finishes available. Our finishes surpass requirements by the American Architectural Manufacturers Association AAMA-2604 specifications. Typical test requirements are 5 years of very minor color change or fade, 3000 hours of salt fog testing and humidity tests. In over 20 years of use, we have yet to have the powder coating need refinishing due to wear.
Can I Install a Gutter at the End of the LockDry Deck?
Yes, a typical gutter used for a roof can be used.
