Secant Piled Walls
Secant piled walls are typically used to control and reduce the ingress of groundwater. Often
used in basement construction, but can be used in various other scenarios where vertical retaining structures are required be it earth, water or both. The secant wall will normally but not always form a part of the permanent works. As you can see below a secant wall is made up of interlocking bored piles. The hard piles (males) are reinforced with the soft piles (females) form the joint and have no reinforcement.
