Technical Aspects
We address specific technical aspects such as durability, imperviousness of steel sheet pile walls, seismic design, and more. Here are the common issues and solution
Durability | Steel sheet piles, commonly used in permanent earth retaining and foundation works, are durable even in unprotected conditions, although corrosion levels can vary by environment. Typical environments include soil, atmospheric, fresh water, and marine settings, with marine being the most corrosive. Regular monitoring and, if needed, additional protection measures like cathodic protection are recommended for harsh marine conditions. |
Watertightness of Sheet Piles | Steel sheet piles are generally impervious, making them ideal for applications needing water flow restriction, such as underground structures. Sealing systems at interlocks enhance water control, reducing risks like settlement and keeping areas dry. Each sealing choice should consider specific site conditions and requirements. |
AMLoCor® - Steel Grade for Maritime Structures | AMLoCor® steel by ArcelorMittal offers reduced corrosion rates in maritime structures, significantly enhancing durability in critical zones. This "low corrosion" steel is especially beneficial in the Low Water Zone and Permanent Immersion Zone, important for high-stress areas in ports and breakwaters. |
Fire Protection | Fire safety is crucial for steel sheet piles used in underground constructions. ArcelorMittal provides extensive research and tools for fire design verifications to ensure safety in fire-prone environments. |
Seismic Design | Despite historical reluctance, sheet piles are effective in seismic areas. Advanced design methods like Finite Element Modeling (FEM) provide accurate predictions of seismic behavior, offering substantial optimization in seismic design. ArcelorMittal encourages contact for further information on dynamic design assistance. |

Enhancing Infrastructure: Key Aspects of Steel Sheet Pile Performance
Design of steel sheet piles
Design Methods for Steel Sheet Piles
Steel sheet pile design encompasses traditional and modern methods tailored to specific project conditions. Historically, designs used the Allowable Stress Design (ASD) method with global safety factors. Today, the Eurocodes, specifically EN 1997 - Part 1 for geotechnical design and EN 1993 - Part 5 for steel structures, recommend a semi-probabilistic approach.
Recommended Practices
The Soil Structure Interaction Method (SSIM) is advised for contemporary designs, although the Limit Equilibrium Method (LEM) remains in use, particularly in Europe. For more intricate or sensitive environments, the Finite Element Method (FEM) offers a detailed approach. Effective design heavily relies on comprehensive soil investigations to enhance accuracy and reduce costs.
Key Design Considerations
Design considerations focus on bending moments, steel grade, and specific reduction factors that affect the structural integrity and cost-effectiveness of the project. Engineers also consider pile drivability based on soil conditions, pile length, and installation equipment.

Methods and Considerations for Designing Steel Sheet Piles
Installation of Steel Sheet Piles
Steel sheet pile installation is a complex process that requires professional expertise and careful consideration of multiple factors. At its core, successful installation depends on a detailed soil investigation, proper equipment selection, and the integration of all system components, including the sheet pile, soil, pile driving equipment, and driving template.
1. Soil Investigation
A thorough investigation of soil conditions is the foundation of any piling job. This step ensures the selection of the appropriate sheet pile size, installation method, and driving equipment. Installation Techniques
2. Standard installation methods include:
- Vibratory hammers
- Impact hammers
- Presses
Driving assistance methods, such as water-jetting, pre-drilling, pre-augering, or blasting (used rarely), may be required depending on the site conditions.
3. Special Applications
Specific installation techniques are necessary for challenging conditions or specialized projects. For example:
- Circular cells or diaphragm cells require precise execution and a tailored procedure.
- HZ-M combined wall systems demand the use of rigid templates or driving equipment with a guiding frame.
4. Execution Speed
The speed of installation varies significantly, depending on soil conditions, sheet pile length, and equipment. Standard sheet pile installations typically achieve 6 to 30 pairs per day.
5. Equipment Selection
Choosing the right pile driving equipment is essential for minimizing nuisances such as noise and vibrations, while ensuring alignment with soil conditions, driving templates, and any necessary assistance methods.
