Sterilization of Large Timbers during Preservative Treatment: How Quickly We Forget
2020 - IRG/WP 20-40902
Air seasoning is a common method of moisture management in utility poles and is done de facto during pole storage prior to treatment. However, extended air drying prior to treatment encourages fungal attack and can facilitate establishment of decay fungi in poles before a protective preservative barrier is applied. This problem can be mitigated by proper air-seasoning methods coupled with heat ste...

Long-term Performance of Treated Timbers in a Sub-tropical Marine Exposure
2023 - IRG/WP 23-11015
The long-term performance of preservative-treated and modified wood in marine exposures was assessed in Brisbane, Queensland, Australia. This report describes the final destructive assessment of the surviving Australian panels after 11 years of exposure. This site presents the potential for attack by shipworms (likely Bankia spp.), pholads (Martesia striata), Limnoria and Sphaeroma terebrans. Mos...
