Sheet piling is a construction technique used to create a barrier in the ground, often for retaining soil or water. It involves driving long, thin sheets of material, usually made of steel, vinyl, or wood, into the ground. These sheets interlock to form a continuous wall, providing stability and preventing erosion. This method is commonly used in various projects, such as docks, basements, and landfills. Sheet piling is effective in managing groundwater and protecting structures from flooding. Its versatility makes it a popular choice in both temporary and permanent applications in civil engineering.
