Validating a short-term laboratory method to assess the resistance of timber to biodegradation by marine wood-borers
2021 - IRG/WP 21-10975
Novel approaches to protecting wood in coastal and marine environments are needed as the use of traditional broad-spectrum biocides are now restricted. Wood is widely utilised in marine environments where it can be rapidly degraded by wood-boring organisms, causing billions of dollars of damage per annum. Biocidal compounds such as CCA and creosote have been popular treatments for timber products ...

Wood modification reduces the feeding rate of the wood boring crustacean, Limnoria quadripunctata
2022 - IRG/WP 22-10993
Adult Adult Limnoria search for new wood once their current piece disintegrates from tunnelling. During this time, they do not have access to wood so experience a period of starvation and must feed again once settled. Wood modification offers protection to marine structures by reducing the feeding rate of Limnoria and therefore can reduce recruitment of adults from distant pieces of wood. Chemical...

Service trial of different materials exposed in jetties at Öresund. Progress report No. 5
2022 - IRG/WP 22-30764
This report contains results of the fifth inspection on the performance of different decking materials – preservative-treated wood, modified wood, natural durable wood, re-cycled plastics and wood-plastic composites (WPCs) - available on the market and exposed since 2013 (some since 2014 and 2016) by the City of Malmö in two jetties near the Øresund Bridge, south of central Malmö in Sweden. T...

A six-year ground proximity trial of TRU-CORE treatments at Innisfail, Queensland
2023 - IRG/WP 23-30775
This article describes an H3 (above ground outdoor) ground proximity field trial that compares the performance against decay fungi of TRU-CORE (also known as the Buffered Amine Oxide Enhancement System) Copper Quat (CQ) with CCA and commodity Alkaline Copper Quat (commodity-CQ) treatments, all in Pinus radiata. The retentions achieved reflected commercial practice, where higher mean retentions are...

Performance of a noise barrier with different wood materials – results from a service trial after 25 years of exposure
2023 - IRG/WP 23-30776
In connection with the construction of the railway connection between Stockholm Arlanda airport and Stockholm city, an 11 km long noise barrier made of untreated European larch was built along the railway line. This provided an opportunity to implement a full-scale study comparing different untreated wood species and preservative treatments. Thus, in March 1996 ten test sections including untreate...

Above Ground Proximity Decay Field Trial of Modified ACQ-A, Wolman® CA-B and Wolman® CA-C in Taiwan
2023 - IRG/WP 23-30793
An above ground proximity decay field trial was established at Chiayi county, Taiwan in July 2016. The purpose of this study was to generate local field performance data for Taiwan for Slash Pine treated with Wolman® CA-B, Wolman® CA-C and a modified ACQ-A product at AWPA UC3B actives retention. After 6 years of field trial, the efficacy of the wood preservative in preventing decay fungi and ter...

International joint field trial on the moisture performance of wood – Set up and first results
2024 - IRG/WP 24-40996
Wood durability to decay stems from its inherent resistance to fungi resistance to fungi. In this regard, wood's ability to withstand moisture uptake plays an important role as the lower threshold for wood decay is a moisture content of 25%. However, the aspect of moisture resistance is not yet sufficiently emphasized as a durability factor, both in the assessment of durability as a material prope...
