This report documents the field performance of wood posts protected with a variety of technologies and exposed in Canadian test sites for 6 to 20 years. Barrier wraps on untreated posts were associated with increased service life under some, but not all, conditions. Further exposure time is needed to assess the impact of barrier wraps on the performance of preservative treated posts. Jack pine posts treated with basic copper carbonate (no co-biocide) showed early stages of decay after 10-years while untreated controls had mostly failed. This suggests a potential solution for organic agriculture. The use of a spike or boot was associated with a lower extent of decay than posts that were installed directly in the ground.
