Durawall PVC Sheet Pile vs. Steel Sheet Pile: Which is the Better Retaining Wall System?
In a time when soil erosion and landslides have become increasingly prevalent due to extreme weather events and flooding, selecting the right retaining wall or sheet piling system has never been more crucial.
These protective structures play a vital role in stabilizing slopes, preventing land movement, and safeguarding properties and infrastructure. Among the available solutions, two options stand out: Durawall PVC sheet piles and traditional steel sheet piles. While both serve similar structural purposes, they differ significantly in durability, cost-efficiency, environmental impact, and long-term performance—factors that are especially important given today’s climate challenges.
Durawall PVC sheet piles offer a significant advantage in corrosion resistance. Unlike steel, which naturally corrodes over time—especially in marine or chemically aggressive environments—Durawall is made from high-quality polyvinyl chloride that does not rust or oxidize. This makes it ideal for long-term use in areas exposed to saltwater or other harsh conditions without the need for additional protective coatings or treatments.
In terms of cost, Durawall is more economical over its lifespan. It requires minimal maintenance and has a lower installation and upkeep cost compared to steel sheet piles, which often demand ongoing maintenance such as recoating, rust removal, and potential replacement due to corrosion damage. These factors contribute to higher long-term costs when using steel.
Environmental impact is another area where Durawall excels. Being inert and non-toxic, Durawall is safe for marine life and does not release harmful substances into the surrounding environment. In contrast, steel sheet piles can negatively affect aquatic ecosystems as they oxidize, releasing iron oxide and other compounds into the water.
Furthermore, Durawall demonstrates superior resistance to chemical exposure and harsh marine conditions. It maintains its structural integrity even when exposed to saltwater, acids, and other corrosive agents, making it highly suitable for coastal and industrial applications. Steel, on the other hand, is far more vulnerable in such settings without costly protective measures.
Overall, while steel sheet piles have traditionally been favored in many engineering applications, Durawall PVC sheet piles represent a smarter, more sustainable choice. With better corrosion resistance, lower maintenance requirements, reduced environmental impact, and enhanced performance in aggressive environments, Durawall stands out as the more efficient and forward-thinking solution for modern retaining wall systems.
