Timber piles have successfully supported structures for more than 6,000 years. Over the years, the methods that man has employed to extend the life of timber piling have evolved to the point that timber piles will last for over 100 years.
How Long Do Wood Pilings Last?
Wood pilings are an important structural element in many buildings, especially in areas prone to flooding or coastal erosion.
They provide support for buildings and help protect them from the elements. But how long do they last? The answer to this question depends on a number of factors, including the type of wood used, the quality of the wood, and the environmental conditions it is exposed to.
Generally, untreated wood pilings can last anywhere from 10 to 30 years. However, this lifespan can be greatly extended with proper maintenance and treatment.
Wood pilings are typically made of pressure–treated softwood or hardwood. Softwood pilings are generally more susceptible to damage from the elements and marine wood borers than hardwood pilings.
Therefore, softwood pilings are typically treated with preservatives to help protect them from decay and rot.
The preservatives used vary depending on the type of wood and the environment it is exposed to, but they typically last anywhere from five to fifteen years.
Hardwood pilings are typically more resistant to decay and rot than softwood pilings. In addition, they are more resistant to marine wood borers.
Therefore, hardwood pilings can last anywhere from 20 to 40 years, depending on the type of wood used
