Wood Piles
Timber piles are made from the trunks of tall straight trees. The more typical species are conifers such as Southern Yellow Pine and Douglas Fir. Untreated timber piles are suitable for temporary situations and where the top of the pile will always be in soil below groundwater level. All permanent timber piles driven in marine environments and where the butt (upper end) will be above groundwater levels require a preservative treatment to resist rot, and insect and marine borer attack.
