Trust in the durability of preserved wood during and after the reclamation of the Zuiderzee
1987 - IRG/WP 4134
A firm belief in the durability of preserved wood must have existed during the reclamation of the Zuiderzee, because thousands of m³ have been utilized. The wood is exposed to attacks of marine borers and other organisms in the marine environment. Was this trust right or wrong? A recent examination was made of creosote impregnated pine posts after 65 years service in a dam, near the Barrier Dam a...

Novel wood treatments improve resistance to the wood-boring marine isopod Limnoria quadripunctata
2017 - IRG/WP 17-10899
The marine isopod Limnoria quadripunctata degrades wooden structures in the sea and causes significant economic damage. Broad-spectrum biocides and naturally resistant tropical hardwoods have failed to prevent feeding by Limnoria and have caused ecological damage. Wood modification is now the favoured method, and resin-based modifications have been effective, while the efficacy of silica-based mod...

Modification of Gmelina arborea wood for utilization in Nigeria
2023 - IRG/WP 23-40986
The level of protection achieved by any wood treatment process is dependent on achieving a sufficient uptake and penetration of the treatment chemicals. This phenomenon is also applicable when considering chemical modification of any wood species. The desired changes in physical, mechanical or durability enhancement of treated species can only be achieved beyond a superficial treatment. For this, ...
