Pressure treated timber piling makes it possible for soil engineers and designers to pass along a variety of cost saving opportunities to owners. While typically thought of as a lower capacity pile, timber has frequently been used in applications engineered for high design loads of 50 tons or more. We offer both treated and untreated piling according to ASTM D-25, ASTM D1760 and AWPA C3 specifications.
