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...

Assessing changes in hardness of furfurylated wood on a nano-scale to mimic levels experienced by the marine wood-boring crustacean, Limnoria
2023 - IRG/WP 23-11016
Wood-boring crustaceans and bivalves can cause severe damage to wooden structures in the marine environment, warranting the need for novel protection systems, such as chemical modifications. Furfurylation increases mechanical properties and resistance of timber species that would usually be susceptible to biodegradation by these borers, such as pine. In rapid laboratory and field testing, furfuryl...

Resistance of phenol formaldehyde impregnated beech (Fagus sylvativa L.) LVL against biodegradation in soil contact
2023 - IRG/WP 23-40965
Alternatives to preservative impregnation are emphasized in Germany and other European countries. Even though these treatments significantly improve wood's resistance to decay, they often do not have a beneficial impact on the dimensional stability. One alternative product, which may be used in ground contact for items like poles and railway sleepers, could be beech (Fagus sylvatica L.) laminated ...

Do naturally sequestered biocidal metals contribute to the marine borer resistance of turpentine?
2024 - IRG/WP 24-11036
Turpentine wood is renowned for its resistance to attack by molluscan marine borers. This resistance is thought to be due to its high silica content, and possibly the presence of other, as yet unknown, compounds. Silica in turpentine wood is present as particles in rays, but in many plant species silica also occurs in cell walls. We hypothesized that Si is present in cell walls of turpentine, but ...
