Altrad Generation's Larssen Range Interlocking Sheet Piles are heavy-duty steel sheet piles designed for temporary and permanent works where standard trench sheets are insufficient. Used in cofferdams, retaining walls, foundation construction, and marine projects, Larssen piles provide a watertight interlock that restricts groundwater inflow, making them the preferred choice for waterfront and marine applications.
Available in seven profile grades from L601 to L607, all with a 600mm width, the Larssen Range covers a spectrum of structural requirements from lighter temporary retention to demanding permanent structures. Key design decisions, including pile length, penetration depth, and ground loading, require specialist advice to ensure the correct specification for your project.
Available in various lengths and strength grades from Altrad Generation branches across the UK and Ireland, with specialist advice and quotations provided on request.

Frequently Asked Questions
Q: What are Larssen sheet piles used for?
A: Larssen Sheet Piles are used in temporary and permanent cofferdams, retaining walls, foundation construction, and marine projects. The watertight interlocking section restricts groundwater inflow, making Larssen piles suitable wherever water exclusion is a design requirement.
Q: What profile grades are available in the Larssen Range?
