4.8.7 Maintenance

Corrosion rates for buried galvanized or coated steel piling, or degradation rates for buried concrete piling,
are typically very low to non-existent, and piling for these types of foundations are usually considered to
last the life of the structure. Special conditions such as exposure to salt air or highly caustic soils in unique
built environments, such as industrial zones, should be considered. Wood piling typically has a more limited
lifetime. Some foundation systems also allow for the removal and replacement of pilings, which can extend
the life of the support indefinitely.
