IMPORTANT: Treated Wood End Use Information

Ground Contact (UC4A) treated wood should be used in the following end use applications:

Ground Level Decks and Walkways

• Treated wood when installed less than 6” above the ground.
• When treated wood is used in an application that does not permit air circulation or water drainage underneath the structure.
• When treated wood is used in an application where vegetation, leaf litter, or other debris will build up and remain in contact with the treated wood product.

Decks and Fresh Water Docks

• When treated wood is used in an above ground application where the treated wood component would be considered difficult to maintain, repair or replace and that component is critical to the performance and safety of the structure. This standard change will affect joists and beams used in above ground decks and fresh water docks, including floating docks.
• When treated wood is wetted on a frequent or recurring basis such as wind and wave action (such as fresh water docks and walkways) or watering systems, swimming pools and hot tubs.

Export Products - Exterior Use
