A collaborative test to determine the efficacy of polyurethane coatings on wood samples exposed in the marine environment
1984 - IRG/WP 4113
Aims are: a) to determine the effectiveness of elastomeric polyurethane as a protective coating against marine wood boring animals in a range of tropical and tempreate sites; b) to compare the adhesion of polyurthane coatings on different wood species exposed in seawater; c) to record the severity of attack in failed samples and to identify the causal marine organisms....

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 ...

Information from COIPM Wood Group
1985 - IRG/WP 4120
During the last COIPM Meeting (which took place in Athens, Greece in September 1984) the Wood Group met and discussed the co-operative work 'Durability in sea-water of wood with plastic wraps and wood treated with polymere'....

Evaluation of Barrier Wrap Systems after 71 Months of Exposure
2013 - IRG/WP 13-40631
A 71 month study of the performance of booted samples in ground contact was conducted in AWPA hazard zone 4. Data indicated that excellent performance of wrapped systems, even over untreated wood, could be obtained. Instances of decay colonization or termite attack could all be attributed to some breaking of the integrity of the barrier system. Good performance for treatment below ground contact...

Controlling marine borer attack of timber piles with plastic wraps
1981 - IRG/WP 479
Plastic films 20 to 40 mils thick have been used for many years to wrap creosoted timber piles in service to protect them from attack by marine borers. As long as the wrap remains undamaged, this procedure provides complete protection to the pile. Properly applied, wraps generally provide protection for 25 yeara or longer. Polyvinyl chloride (PVC) and polyethylene (PE) films are specially formulat...

Information from the COIPM Wood Group
1988 - IRG/WP 4146
Abstract from the COIPM minutes: Wood in marine environment: Mrs Gambetta stated that the main item discussed by the Group was the collaborative work to test the durability of heat shrinkable polyolephin sheating materials for the protection of wood against marine organisms. The work began last year when wood samples were sent out to the participants. Three samples of Pinus sylvestris wrapped in ...
Field Liners as physical barriers to prevent wooden utility pole decay in soil: An accelerated field simulation trial
2008 - IRG/WP 08-20384
Field Liners (FL’s), plastic sleeves used to protect in-ground wooden poles from fungal and termite damage, have been tested before as physical barriers to prevent contact between soil and wood and to retain wood preservative treatment. These earlier studies concentrated mostly on creosote preserved poles and early generation FL’s which were cumbersome in their application. The newer generatio...

Field Performance of Old-Growth and Second-Growth Western Red Cedar Fence Posts with and without Barrier Wraps
2015 - IRG/WP 15-10838
Many authors have suggested natural durability may be lower in second-growth western redcedar than in old-growth. One potential means of offsetting a decline in durability is use of physical barriers to separate the wood from soil. In the present work we compared the durability of old-growth and second-growth western red cedar posts, with and without barrier wraps, in a field test. After ten year...
