Sheet pile walls are driven into the ground and are composed of a variety of material including steel, vinyl, aluminum, fiberglass or wood planks. For a quick estimate the material is usually driven 1/3 above ground, 2/3 below ground, but this may be altered depending on the environment.
This example of multiple structures includes a massive seawall and riprap revetment. A bulkhead is a retaining wall, such as a bulkhead within a ship or a watershed retaining wall. It may also be used in mines to contain flooding. Coastal bulkheads are most often referred to as seawalls, bulkheading, or riprap revetments.
Typically in the form of a horizontal wire or rod, or a helical anchor, a tieback is commonly used along with other retaining systems (e.g. soldier piles, sheet piles, secant and tangent walls) to provide additional stability to cantilevered retaining walls. [1]
The Alaskan Way Seawall is a seawall which runs for approximately 7,166 feet (2,184 m) along the Elliott Bay waterfront southwest of downtown Seattle from Bay Street to S. Washington Street. [1] The seawall was being rebuilt in the 2010s as part of a waterfront redevelopment megaproject estimated to cost over $1 billion.

Sheet piles are used to restrain soft soil above the bedrock in this excavation. Sheet piling is a form of driven piling using thin interlocking sheets of steel to obtain a continuous barrier in the ground. The main application of sheet piles is in retaining walls and cofferdams erected to enable permanent works to proceed. Normally, vibrating ...
A heavily damaged piling structure can be reinforced by cutting out the damaged section and replacing it with preservative-treated wood. [14] Wrapping piles with plastic barriers can provide protection from marine borers for 25 years or more. [14] Pile reinforcement with concrete can be sufficient by filling the void with coarse stone and ...
