CCA Timber Life Expectancy

CCA Timber Life Expectancy

CCA Timber Life Expectancy

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

•2.5 pcf - saltwater applications
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
