Chemical defense of trees and wood natural durability: from protection to valorization
2019 - IRG/WP 19-10943
Natural durability of wood is defined as “the inherent resistance of wood against various wood-destroying organisms” (European standard EN 350-1). This property is due in particular to heartwood extractives. However, the wood natural durability is included in a wider defense system, and other organs such as bark and roots also host protective compounds. Studying the mechanisms on which global ...

CCA wood preservative: Trust with destiny
2019 - IRG/WP 19-30731
This paper traces the history of Copper-Chrome-Arsenic (CCA) and its current status in India and worldwide. CCA was invented as ASCU at the Forest Research Institute, Dehra Dun in 1933 by Dr. Sonti Kamesam. Although its efficacy was doubted by the British colonial rulers resulting in several hiccups at home, the patent rights were purchased by US Bell Telephone Co. and it was adopted by the US woo...

From wood protection to health protection: larvicidal potential of formulations containing Sextonia rubra wood residues extract against Aedes aegypti mosquitoes
2020 - IRG/WP 20-10968
French Guiana is a French overseas territory almost entirely covered by Amazonian rainforest and characterized by its incredible biodiversity. Several woody species harboured by this tropical forest are exploited sustainably for timber industry. They are commercialized notably for carpentry and outdoor applications because of their remarkable natural durability. Among them, stand Dicorynia guianen...

Towards a microactuator-sensing network for the structural health monitoring of wood
2023 - IRG/WP 23-50380
Timber structures decay over time with degradation in their structural integrity. Changing environmental conditions, varying loads, exposure to moisture or insect attacks lead to changes in their vibrational response behaviour. Here we present a low-cost device used as a triggered exciter to enable the monitoring of the structural integrity of timber bearers or even power poles in electricity netw...

Structural health assessment of wood - A comparison of methods for determining the spatial spread of fungal infestation in beams and rafters
2025 - IRG/WP 25-11051
Wood decay in buildings can cause severe economic losses, require comprehensive refurbishment, and removal of decayed wooden elements from the building. The latter aims at restoring the structural integrity of the component or the entire building through replacement, and at preventing the infestation from spreading further. In practice, components are cut out of the structure to such an extent tha...

The iTrussT project – Advancements in timber bridge design, preservation, and monitoring
2025 - IRG/WP 25-20751
The Norwegian research project iTrussT (2025–2028) aims to advance timber bridge design and unlock wood’s full potential as a sustainable solution for modern infrastructure. It addresses three critical challenges: First, fatigue testing of glued laminated timber lamellae will provide deeper insights into shear failure mechanisms, supporting the development of safer, more efficient structures a...
