Performance of Native and Copper-Ethanolamine-Treated Wood Exposed to Seawater at Port of Koper, Slovenia

The application of wood in seawater is one of the most challenging. Impregnated wood is exposed to leaching and to various marine borers, Limnoria sp. and Teredo sp. being the most important ones. The present research investigated the durability of pine wood impregnated with copper-amine based prese...

Limnoria sp. and Teredo sp. being the most important ones. The present research investigated the durability of pine wood impregnated with copper-amine based preservative solution (Silvanolin) of different concentrations exposed to the seawater according to EN 275 standard. Performance of Silvanolin treated wood was compared to the performance of reference wood (Quercus sp.
Castanea sativa
Larix decidua). After 10
18 and 32 months of exposure
specimens were removed and assessed. The results show clearly that the reference wood species were completely degraded after 10 months of exposure. On the other hand
it became evident that Silvanolin prolonged the service life of wood exposed to the sea. The specimens impregnated with the lowest concentration of preservative solution (cCu = 0.31 %) were slightly decayed. The specimens
impregnated with higher concentrations of copper (cCu > 0.31 %)
