that it may receive the preservative. Once a timber pile is sufficiently
dry, it is placed into a pressurized cylinder. The cylinder
undergoes a period of vacuum and then is flooded with liquid
preservative, which is then pressurized, forcing preservative into
the wood cells. Once sufficient preservative has been absorbed,
a final vacuum is used to ensure that excess preservative is not
retained in the wood cell, and the piles are removed from the cylinder.
Analytical testing is conducted to ensure the preservative
has penetrated the wood and that the proper retention levels have
been met according to the AWPA standards. It is important to note
that in some piling the preservative treatment does not penetrate
the entire pile, but creates a protective envelope around the piles
circumference. It is important to avoid puncturing or damaging
this protective envelope prior to or during installation. Should
the outer area of the pile become damaged, or if the pile is cut
or drilled after treatment, the protective envelope will need to be
repaired. AWPA M4 standard provides procedures for the proper
handling, storage and field treatment of timber piles to address any
repairs that may be needed.
Timber piling’s long history has allowed its users to create
standards for the proper specification of timber piles. The various
standards setting bodies have continued to meet to work toward
improving their product. t
