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 ...

Laboratory and field evaluations of bio-based termiticide containing Arnica extract from Berkem Biosolutions® against native and Formosan subterranean termites
2024 - IRG/WP 24-11049
Arnica extract from Berkem Biosolutions® is a 100% plant-based ingredient, rich in active molecules, particularly polyphenols, specially adapted to the needs and challenges of termite protection. The efficacy performance of a bio-based termiticide product containing Arnica extract from Berkem Biosolutions® had been evaluated both in soil treatment and in wood protection treatment against native ...

Modelling the service life of wood in ground contact – Verification of remotely sensed soil data from the reanalysis dataset ERA5-Land using in-situ measurements at a test site of utility poles in Eastern Norway
2024 - IRG/WP 24-41003
This study compared soil moisture and temperature estimates from the 5th European reanalysis (ERA5-Land) dataset with in-situ measurements to assess the accuracy and applicability of ERA5-Land data for modelling the service life of wood in ground contact. The ERA5-Land soil temperature estimates showed a moderate correlation with the in-situ temperature measurements (Spearman’s ρ of 0.73) and a...

Performance of Douglas-fir cross laminated timber (CLT) subjected to elevated humidity in a ground proximity field test for 6 years
2024 - IRG/WP 24-41010
The ability of insecticidal soil drenches or spray-on insecticide/fungicide treatments to protect mass timber elements exposed in a high moisture environment but out of direct soil contact was assessed using a modified AWPA ground proximity test established in 2017. Three-ply Douglas-fir CLT pieces measuring 305 x 355 x 105 mm (L x H x W) were installed at the Harrison Experimental Forest (HEF) (S...
