Sheet piling walls are constructed by driving prefabricated sections into the ground. Soil conditions may allow for the sections to be vibrated into ground instead of it being hammer driven. The full wall is formed by connecting the joints of adjacent sheet piling sections in sequential installation. Sheet piling walls provide structural resistance by utilizing the full section. Sheet piling are most commonly used in deep excavations, although reinforced concrete sheet piling have also being used successfully.
Sheet piling is the most common because of several advantages over other materials:
1. Provides high resistance to driving stresses.
2. Light weight
3. Can be reused on several projects.
4. Long service life above or below water with modest protection.
5. Easy to adapt the pile length by either welding or bolting
6. Joints are less apt to deform during driving.
Sheet piling walls are constructed by:
1. Laying out a sequence of sheet piling sections, and ensuring that sheet piling will interlock.
2. Driving (or vibrating) the individual sheet piling to the desired depth.
3. Driving the second sheet piling with the interlocks between the first sheet piling and second "locked"
4. Repeating steps 2 & 3 until the wall perimeter is completed
5. Use connector elements when more complex shapes are used.
