Type II sheet piles are primarily used in applications where water tightness is required, such as in retaining walls, cofferdams, and seawalls. The interlocking edges of Type II sheet piles create a secure seal that prevents water from seeping through the structure. This makes them ideal for projects that involve excavations below the water table or construction near bodies of water. Additionally, Type II sheet piles are commonly used in marine construction for bulkheads and flood protection systems due to their durability and resistance to corrosion. These sheet piles are available in various lengths and thicknesses to suit different project requirements, making them a versatile choice for engineers and contractors working on waterfront projects requiring reliable and effective containment of water.
