Natural durability of some commercial timbers of Sarawak, Malaysia in tropical marine environment
2005 - IRG/WP 05-10561
The abundant supply of timber resources in Sarawak makes timber an ideal choice to be used for marine construction. The natural durability of the main commercial timber species of Sarawak in ground contact is well established but the same is not available for marine environment.
This study was conducted to assess the natural durability of 28 commercial timber species in tropical marine environmen...

A collaborative test to determine the efficacy of poyurethane coatings on wood samples exposed in the marine environment. 1st Interim Report
1988 - IRG/WP 4145
Wood samples coated with elastomeric polyurethane (ca. 50 mils thick) were exposed for up to 2 years in 12 tropical and temperate marine test sites with known teredinid, pholad and/or crustacean infestations. All uncoated control samples were destroyed or partially destroyed. Polyurethane-coated samples were not attacked, the surfaces of the coating were sound and the polyurethane adhered well to ...

Status of the Working Group on Preservation of Wood in the Marine Environment - Questionnaire results
1977 - IRG/WP 434
At the joint meeting of the IRG and COIPM dealing with preservation of wood in the marine environment, it was suggested that a Marine Group should be formally recognised within IRG. It was agreed that a questionnaire (Document No: IRG/WP/424) should be circulated to determine the views of the membership on the future status of this group. The results of this questionnaire are presented....

Wood preservation in Kenya
2000 - IRG/WP 00-40191
Current research on wood preservation in Kenya is mainly on the development of biological control of wood-destroying termite species, using mycoinsecticides. The major research institutions include the Kenya Agricultural Research Institute (KARI), Kenya Forestry Research Institute (KEFRI), Moi University and the International Centre for Insect Physiology (ICIPE). Training institutions include Fore...

The efficacy of polyurethane coatings on wood samples exposed in the marine environment. Final Report -10 Year Assessment
1996 - IRG/WP 96-10170
The results of an IRG collaborative marine trial to investigate the long-term permanence and efficacy of polyurethane coatings against marine borers are reported. PU-coated wood samples were exposed at a range of sites from tropical to cold temperate locations. The marine borer species present at the sites included teredinids, pholads, limnoriids and sphaeromatids so that each site offered its own...

Generic code of good practices for wood protection facilities. Part 1: Wood protection (antisapstain) facilities
1993 - IRG/WP 93-50003
In general, the potential of high toxicity (aquatic and human) of wood protection (antisapstain) chemicals dictates the need to protect the environment and humans from its harmful effects. This document is a compendium of recommendations for the design and operating practices of wood protection facilities. The suggested recommendations focus on achieving the objectives of protecting the environmen...

Leaching of CCA preservative from treated timber in marine environment
2001 - IRG/WP 01-30254
Knowledge on the amount of preservatives leaching out of treated wood is essential to optimise the chemical loading in various species of timber required for different end uses. In order to gain more insight into this aspect, the residual CCA content in 40 treated timber panels belonging to 14 species removed on destruction by marine organisms from a series of durability tests conducted in Kochi w...

Eastern subterranean termite responses to three soil pesticides
1990 - IRG/WP 1432
In laboratory assays simulating field conditions, tunneling and mortality of Reticulitermes flavipes (Kollar) workers were evaluated in sand treated with aqueous solutions of formulated chlorpyrifos, isofenphos, and disodium octaborate tetrahydrate. Chlopyrifos and isofenphos were evaluated at concentrations of 500 and 1000 ppm (weight of active ingredient / weight of sand), and disodium octaborat...

A comparative study of CCA type C and B treated poles in service
1993 - IRG/WP 93-50001-05
CCA K33 type B and C treated utility poles, 9 pieces of each treatment type, were analyzed for preservative retention after 11 years in use. Borings were taking 1 m above and 0.3 m below the ground line. Also total amount of copper, chromium and arsenic was determined in soil surrounding the poles. The solubility of these active components in soil was monitored by using different leaching procedur...
