Waterways
Ecoboard Specifications (Seawall, Boardwalk and Retaining Wall) Ecoboard is increasingly used as a wood alternative for seawall, boardwalk and retaining wall applications. Additional testing has been conducted to determine water absorption, coefficients of friction and expansion, and UV stability.

Decking & Bulk Heading 

Fasteners

Decking - Stainless Steel Square Head # 10 decking screws are highly recommended.
- Pre-drilling is required on all Decking boards if screws are not self-tapping.
- All fasteners should be placed no closer than 1” from any edge nor protrude from any board closer than 1” form any edge.

Bulk Heading - Pre-Drilling is required when using 40 or 60 penny nails. Whaler spacing should be 36” or less for 2” x 10” and 60” or less for 3” x 10” boards.

Design Considerations

Board Spacing - ECOBOARD® will expand and contract linearly approximately .000064/in./in./deg. F. this can be calculated by board size as shown by the following examples:

         5/4 x 6 x 12’ = approximately 1/4” over a 30°F change in temperature.
         2 x 6 x 12’ = approximately 1/3” over a 30°F change in temperature.

When installing in temperatures over 45°F butt all ends as closely as possible. Spacing between boards is at the discretion of the consumer.

Before starting any building project be sure to check with the proper governing agencies or Associations for any approvals, permits or covenants that may apply to your home.

Spans - Decking -Suggested decking span is 16” on center for both the 5/4” and 2”x 6” boards for the designs shown below. Call for technical evaluation on alternative designs.

Railings - Posts for railings should be no more than 4 feet apart and tag bolted to the fascia beam or joist - Do Not Notch Posts! Snow rail designs must be supported every 2 feet with blocker piece to avoid possible sagging. See design criteria on following pages.
