Sheet pile walls can be used in a variety of ways for riverbank protection. For new embankments they can ensure watertightness, support, and stabilization. They are also used to strengthen existing embankments and can serve as a cutoff.The required watertightness of sheet pile cutoffs is often obtained through natural deposition of soil in the interlocks.
For the stability, sheet pile walls can be designed to mechanically reinforce the bank. In this case, the flexibility of the steel sheet piles can be very useful: they follow the potential displacement of the soil while keeping their full resistance.
Lastly, sheet pile walls can also protect buildings from subsidence. In this case the sheet pile wall is driven outside the embankment, usually along the toe of the embankment.
