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 for use in the construction invented by Tryggve Larssen   . It's 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.
About Larssen Sheet Piles
The segments lock together using a variety of interconnections. To reduce the filtering space, mixed sealant is injected.
Additionally, it may be combined with the use of dowels, metal beams and pipes. Metal dowels are hot-rolled steel and cold-rolled. Larssens are used in foundation pits, coastline strengthening, bridge construction, piers, tide control, flood protection, agriculture irrigation, water reservoir and other work requiring extremely strong support in a narrow geometry.
