harm marine life and is safe for the environment. Many docks have been built with Trex decking.
As long as dock is in intermittent contact with water, i.e., splashing and not in continuous direct
contact with water, the durability of the Trex decking should not be affected.
Two minor revisions to the installation guidelines are recommended. For docks we recommend a
3/8” width to width gap between boards to allow for increased drainage due to increased contact
with water. In addition, stainless steel fasteners should also be utilized
Finally, if there is sufficient contact with the dock and gasoline, grounding of the dock is also
recommended.
Trex, approved by most building codes, is sold in most standard dimensions, including 5/4x6 in. and 2-by.
