Performance of resin-treated solid wood and laminated veneer lumber (LVL) under marine conditions
2021 - IRG/WP 21-10973
Wood is a traditional building material in the marine environment, where it is exposed to extremely harsh conditions. Most of the indigenous softwood and hardwood species in Europe are not durable against attack by marine organisms. Recently, wood modification has been considered as an alternative to protect non-durable wood species under use class (UC) 5 (EN 335, 2013) conditions. The present stu...

Post-layup protection of mass timber elements in above ground protected exposures: 2-year results
2022 - IRG/WP 22-30766
Mass timber has seen increased use as a building material for low and mid-rise construction in recent decades. The durability of mass timber elements has not been fully examined and the effects of wood destroying organisms on this these materials merits attention. The effectiveness of currently labeled soil termiticides and passively applied biocides at post-construction or as remedial agents need...

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 ...
