When driving piles for a construction project, understanding the types of piles and how to use them is crucial. These conditions can cause pile refusal, borehole collapse, or unexpected settlement—inflating costs and delaying timelines. Vertical ground anchors (tie-downs) are also classified as deep foundations. Impact driving steel piles through the water produces extremely high underwater sound levels that can harm aquatic wildlife. Jan 31, 2025 · These piles often serve as temporary or permanent foundations for in-water and over-water infrastructure, according to Senior Estimator Bill Shorey.
