How long should new treated wood poles resist decay, depending on soil conditions?

New treated wood poles are designed to resist decay for a period that typically ranges from 10 to 20 years, primarily depending on the environmental and soil conditions where they are installed. This range reflects the effectiveness of the chemical treatments used to preserve wood against rot and insect damage, which can vary significantly based on local climate, soil moisture levels, and the presence of decay-causing organisms.

In environments that are particularly moist or have a high concentration of microorganisms in the soil, decay can occur more quickly, thereby shortening the lifespan of the treated wood. Conversely, in drier conditions or soils with fewer decay organisms, the poles may last closer to the upper end of that range.

This information highlights the importance of considering local conditions when determining the expected lifespan of treated wood installations, making the provided answer aligned with industry standards and practices.
