Steel sheet piles have been used for over a century in ports, flood protection systems, retaining walls, and infrastructure projects around the world. Yet despite their long track record, many misconceptions still surround their performance, sustainability, durability, and applications.

In this video series, we'll take a closer look at five common myths about steel sheet piles and compare perception with reality. Whether you're a civil engineer, project owner, consultant, contractor, or simply curious about modern infrastructure solutions, these short videos will help separate the facts from the fiction.

Explore each myth below and discover what steel sheet piles can really do.

Do steel sheet piles corrode too quickly?

Do steel sheet piles have a lower long term performance VS substitute materials?




 

Reality: Modern sheet piles are designed with high-quality steel grades, coatings, and even corrosion-resistant alloys (e.g., ASTM A690 for marine environments). With proper design, they can last 50–100 years in aggressive environments.

Many quay walls built in the 1960s with sheet piles are still in service today, with minimal maintenance.




 

Reality: Steel sheet piles are ductile, flexible, and repairable, compared to other solutions such as concrete which have more a brittle behaviour. They perform especially well in seismic or dynamic loading conditions, which makes them more reliable in many defence and marine applications.
 

Are steel sheet piles only for temporary applications?

Is installation of sheet piles noisy and disruptive?

 

 

Reality: While they’re excellent for temporary cofferdams, sheet piles are also widely used in permanent structures such as quay walls, flood defenses, bridge abutments, and underground car parks. Their long service life and strength make them a permanent solution in many critical infrastructures.
 

 

 

Reality: Modern installation methods (e.g., press-in piling, vibratory hammers with variable moments) have drastically reduced noise and vibration. In urban or sensitive environments (even near hospitals or military bases) sheet piles can be installed quietly and efficiently.

Are steel sheet piles too expensive compared to alternatives?

 

 

Reality: The upfront cost might look higher than some materials, but when considering speed of installation, reduced excavation, less concrete use, and reusability, steel sheet piles are often the most cost-effective solution over the lifecycle of a project.

Bonus: In temporary applications, sheet piles can be extracted and reused multiple times, further improving cost efficiency.
