CCA Timber Life Expectancy
CCA Timber Life Expectancy
(OP)
I am looking for a timber design code that specifically discusses the life expectancy of CCA treated timber piles within the salt waters of the United States. I typically use the NDS from American Wood Council to design timber piers but I am doing a post-mortem and need a published source.





RE: CCA Timber Life Expectancy
AWPA specifies treatment depending on location
UC5A Saltwater exposure – north of San Francisco and New Jersey
UC5B Saltwater exposure – south of San Francisco on West coast, New Jersey through Georgia on East coast
UC5C Saltwater exposure – south of Georgia, Gulf Coast
