What are Secant Pile Walls?

Secant pile walls are a type of retaining wall that are commonly used in construction to provide support for excavations, as well as to stabilize slopes and prevent landslides. These walls are made up of intersecting piles that are drilled into the ground and then reinforced with concrete. The piles are typically made of steel or concrete and are spaced at regular intervals to provide the necessary support. Secant pile walls are often used in urban areas where space is limited, as they can be constructed quickly and do not require a large amount of equipment or materials.
