Untreated wood in contact with the ground lasts only 3 to 12 years, whereas species like red pine, jack pine and Douglas fur last 25 to 40 years when factory pressure-treated. The importance of preservative-treated wood is well established in modern farm building construction. Treated wood poles and splash planking make a quickly-erected and durable foundation system for a wide range of buildings. This leaflet offers tips on the treatment, identification, and use of pressure-treated wood.
