A sheet pile is a type of construction material used to create a barrier in soil or water. Made from steel, concrete, or wood, these long, thin sections are driven into the ground to form a continuous wall. They are commonly used in projects like retaining walls, waterfront structures, and excavation sites to prevent soil erosion and manage water flow. The installation of sheet piles involves driving them vertically into the ground, often using specialized equipment. Once in place, they provide stability and support, making them essential for various civil engineering applications, including docks, basements, and landfills.
