Larssen sheet piling

Larssen sheet piling is a kind of sheet piling retaining wall. Segments with indented profiles (troughs) interlock to form a wall with alternating indents and outdents. The troughs increase resistance to bending. The segments are typically made of steel or another metal.

Larssen sheet piling was developed in 1906 by Tryggve Larssen. Its applications include piers, oil terminals, waste storage facilities, shoreline protection, bridges, houses, buildings, dry docks other construction sites and for the strengthening of pond banks, preventing slumping into a pit and flooding.
