Field test of Canadian softwood concludes with positive results

When stricter standards for pressure treated wood products were implemented in 2012, it forced many treaters to switch from Canadian species to those from the US, Europe and New Zealand. Fortunately, an ongoing field stake test has yielded positive results for two of the most common Canadian wood species, white spruce and hemlock. The objective of this ten-year study, which began in 2010, is to demonstrate that CSA standards will comply and perform well in Korean environments. The 2015 midway review showed that all treated specimens were free from fungi and termite attacks while the controls were severely damaged. As a result, South Korean scientists have recommended the revision of Korean standards.
