What is it?

Sheet pile retaining walls are one example of a continuous wall system. They retain earth, water or other fill materials and are thinner in section compared to masonry walls. General uses include waterfront structures (seawalls, bulkheads), diversion dams (cofferdams), riverbank protection and temporary excavation support to retain the sides of cuts made in earth. Sheet piles are typically steel due to availability and higher strength. However, sheet piles may also be constructed with reinforced concrete or timber for some applications. Sheet pile walls are one example of a continuous wall system. Other examples include tangent or secant pile walls, slurry walls, or soil-mixed walls.
