Most Important Factors for a Successful GeoDeck Installation
- Do not butt boards end-to-end on the main area of your deck. When installing a deck that requires lengths greater than a single board (i.e., over 20), use our feature strip as a divider rather than butting boards end-to-end.
- The amount of open air space under the deck will determine which boards need to be used. Open air space is defined as the distance from the grade to the top of the joists.
- If there is 24" or more of open air space, either Tongue & Groove or Traditional boards can be used.
- If there is less than 24" of open air space, only Traditional boards can be used with a 1/8" space between boards.
Do not use Tongue & Groove boards with less than 24" of open air space.
- When using the Tongue & Groove boards, leave at least two sides of the under-deck space open for cross ventilation. Two sides of the deck must be open or lattice only. Solid cladding or skirting can be used with decks built with Traditional boards that have a 1/8" space between them.
- All face fasteners must be located a minimum of ¾" from the end of the boards.
Failure to follow these instructions risks voiding the GeoDeck warranty.
