Pressure Treated Lumber for Docks

To answer some of my questions this week....yes, you can indeed use pressure treated lumber for building docks. We follow the guidelines from the American Pole and Timber organization.  The following is a link to their website and their statement on dock materials:

Dock Building Materials
Treated Wood is the most preferred material for docks. Choose the right treatment level depending on the kind of water you are building in:

• Fresh water: A minimum of .60 pcf pressure treated wood
• Saltwater: 2.5 pcf pressured treated wood (or higher) is required​

Most lumber yards offer the option of purchasing the extra treated .60 pcf wood above a 2"x8".  It is more expensive, so be sure to get your pricing before sending your estimate to the customer :)
