Sheet piling is a construction technique used to create a barrier in the ground, often for retaining soil or water. It involves driving long, vertical sections of steel, concrete, or wood into the ground, which interlock to form a continuous wall. This method is commonly used in waterfront construction, excavation support, and land reclamation projects. The primary purpose of sheet piling is to prevent soil erosion and manage groundwater levels. It is effective in stabilizing slopes and creating safe work environments during construction. Additionally, sheet piling can be used to create temporary barriers for flood control or to protect sensitive areas from environmental impacts.
