Decking

GeoDeck™ Frequently Asked Questions

What is the GeoDeck Deck System?

The GeoDeck Deck System is a state-of-the-art decking system
manufactured from a combination of recycled and other plastic, blended with a Biodac® formulation of cellulose fiber and minerals. This exclusive process enables the creation of a range of durable, lightweight boards for decks and other outdoor applications.

What Makes GeoDeck Different From Other Composite Deck Systems?

The open chambers within GeoDeck allow for air circulation keeping your deck cool to the touch and comfortable to walk on whatever the outside temperature. Other brands are made of solid materials which tend to retain heat.

What applications can GeoDeck be used for?

GeoDeck is versatile enough for decks, porches, patios, pool and hot tub surrounds, walkways, docks, boat slips, and just about any other application you can imagine.

Can GeoDeck be painted or stained?

GeoDeck boards come in three attractive colors: Cedar, Mahogany, and Driftwood. Painting or staining is not required, but if desired can be done using a high-quality acrylic latex primer and topcoat. Please note that painted GeoDeck surfaces lose some slip resistance and will require annual maintenance.

The deck boards have some color variation. Is this normal?

Yes. Like lumber or any natural product, GeoDeck may vary slightly in color, creating a distinctive and attractive look as found in nature.

Will GeoDeck fade over time?

GeoDeck is made with Biodac® a patented ingredient that makes GeoDeck virtually fade resistant. GeoDeck maintains its beautiful appearance from season to season, through sun, rain and snow.

Why don’t GeoDeck boards fade like other composites?

Most composite products are made with wood flour or chips and plastic. The lignins found in wood products are a major contributor to fading. GeoDeck uses Biodac® rather than wood chips as its fiber source. Biodac has low amounts of lignins and consequently its GeoDeck products are more resistant to fading.

In what lengths, styles, and colors are GeoDeck boards available?

GeoDeck Traditional and Tongue & Groove boards are available in a 5/4” x 6” profile dimension. Our Heavy-Duty Commercial board is available in a 6/4” x 8” profile dimension. Stock lengths are 12’, 16’, and 20’. GeoDeck boards can be purchased in three fade-resistant colors: Cedar, Mahogany, and Driftwood.

Are GeoDeck boards strong and durable?

Yes. The special blend of ingredients and engineered profiles make this product 30-50% stronger than other composite decking materials. GeoDeck boards are stronger than most of the leading composite boards on the market. Their engineered profile provides superior strength and durability.

Does GeoDeck meet National Building Code Requirements?
GeoDeck is BOCA/ICBO/ICC listed. (ICC-ES Legacy Report No. 21-71, former BOCA Report No. 21-71).

How do I clean GeoDeck?

GeoDeck can be cleaned with any general-purpose household cleaner and/or degreaser. The use of an industrial cleaner or rubbing alcohol along with a wire brush is recommended for stubborn stains.

Does GeoDeck cost more than wood to maintain?

The initial cost of your GeoDeck might be a bit more than other surface materials but compared with wood products, it will save you tremendously in time, effort, and money during the life of your deck.

Consider the following before purchasing a wood deck:

The decking material represents less than 15% of the total cost of most decks.
GeoDeck requires no annual maintenance and very little care.
All GeoDeck profiles are manufactured in uniform lengths and widths. This helps to decrease installation time significantly over wood materials.
GeoDeck is backed by a 20-year limited warranty.
GeoDeck does not split, decay, rot or warp and is highly resistant to termites.

Why is GeoDeck a superior alternative to pressure-treated lumber?

Unlike pressure-treated pine, GeoDeck profiles will not split, crack, warp, rot or decay. The boards contain no knots and are highly resistant to termites. They’re easy to maintain and require no painting or annual sealing so you have more time to enjoy your deck. And GeoDeck does not contain toxic materials.

What is GeoDeck’s warranty?

GeoDeck comes with a 20-year limited warranty that provides comprehensive coverage against splintering, splitting, rot or decay, and termite damage.

Is GeoDeck safe for family, friends, and the environment?

Yes. GeoDeck will not splinter so it’s kind to bare feet. It’s slip resistant, especially when wet, and meets ADA standards. GeoDeck does not contain toxic materials, hazardous chemicals or preservatives.

Should allowances be made for expansion and contraction of GeoDeck boards?

Yes, it is important to note that all composite and plastic-based products will experience some degree of expansion and contraction with changes in temperature. Longer boards expand more than shorter boards. See the GeoDeck Installation Instructions for more detailed installation information.

How can I cover the exposed ends of GeoDeck boards?

There are several ways in which board ends can be covered. Using the “picture frame” technique, you can run a Traditional board perpendicular to the deck boards. This covers the board ends and adds beauty and balance to the deck. You can also use GeoDeck End Caps, custom trim piece, or GeoDeck Fascia board.
