Corrosion Resistance of Helical Piles: Protecting Your Foundation for the Long Term

Corrosion Resistance of Helical Piles: Unmatched Protection for Your Foundation

At Piers and Piles, our helical piles are built to last, specifically engineered to resist corrosion and ensure the long-term stability of your foundation. Corrosion is one of the biggest threats to foundation integrity, especially in areas with challenging soil conditions like Long Island, Brooklyn, and Queens. That’s why we utilize advanced corrosion protection features, including hot-dip galvanizing, to provide a durable solution that stands the test of time—even in high-moisture or salt-rich environments. Our corrosion-resistant helical piles offer unparalleled protection against the elements, safeguarding your property’s foundation for decades.


In this guide, we’ll explore the key factors that contribute to corrosion in helical piles, the cutting-edge technology we use to combat it, and why investing in corrosion-resistant helical piles is essential for the long-term health and stability of your structure.

The Importance of Corrosion-Resistant Helical Piles

When it comes to foundation stabilization, corrosion is one of the most significant threats to the longevity of helical piles. In areas where the soil is rich in salt, has a low pH, or retains excess moisture, the threat of corrosion significantly increases. This is especially true in coastal regions like Long Island, where cities such as Hampton Bays and Montauk frequently deal with groundwater and flooding issues, as well as in Queens neighborhoods like Rockaway Beach, where saltwater infiltration and high moisture levels can rapidly corrode unprotected steel foundations.

 

At Piers and Piles, we understand the critical role corrosion resistance plays in safeguarding your property. That’s why we’ve invested in advanced technology to ensure our helical piles are built to withstand the harshest soil conditions. Our helical piles are hot-dip galvanized to protect against the damaging effects of salt, moisture, and other corrosive elements commonly found in these regions. By adding a thick layer of zinc, we create a barrier that extends the lifespan of the piles and prevents structural failures that could compromise your foundation.

Factors That Affect the Corrosion Life of Helical Piles

The corrosion life of helical piles depends on various factors that influence how quickly they degrade, especially in challenging environments like Long Island, Brooklyn, and Queens. Understanding these factors is critical for ensuring long-term foundation protection.

 

  • Soil Composition and Water Content: Soils with high moisture levels, like those found in coastal regions, accelerate corrosion by promoting electrochemical reactions that wear down steel.
  • Soil Resistivity: Low soil resistivity, typically found in salty or clay-rich soils, increases the risk of corrosion. In areas like Long Island, where saltwater may infiltrate the soil, lower resistivity can mean faster corrosion.
  • Seasonal Variations and Groundwater Exposure: Changes in groundwater levels due to rainfall or seasonal shifts can affect the corrosion rate. In regions where groundwater fluctuates, the piles are exposed to varying conditions, increasing the likelihood of corrosion.
  • Salt Content in Coastal Regions: Long Island’s proximity to saltwater introduces higher salt ion concentrations into the soil, which can aggressively corrode unprotected steel.
  • Steel Imperfections and Stress Concentration: Any inconsistencies in the steel’s structure or stress from the installation process can create weak points, making those areas more susceptible to corrosion.
 

As contractors, we have a responsibility to consider these factors when choosing corrosion-resistant helical piles to ensure the longevity and stability of your foundation. It’s also our job as certified helical pile installers to pay close attention to critical technical forces during installation, such as torque, axial load, and lateral resistance, ensuring that the piles are installed with precision and reach stable soil strata without losing integrity—just one of the many reasons it’s important to hire contractors that are reliable, licensed, and stand behind their work like Piers and Piles.

Corrosion Protection Features of Our Helical Piles

 

At Piers and Piles, we design our helical piles to withstand the toughest environmental conditions, ensuring long-lasting durability and optimal corrosion protection. Our corrosion-resistant technology is vital for safeguarding your foundation in areas with aggressive soil conditions like Long Island, Brooklyn, and Queens.

 

Here’s how we ensure our helical piles stand the test of time:

 

  • Hot-Dip Galvanizing: Our helical piles are coated with a thick layer of zinc using the hot-dip galvanizing process. Following ASTM A123 standards (Grade 75), the zinc coating is at least 3.0 mils thick, equating to 1.7 oz/ft² of zinc. This sacrificial zinc layer corrodes before the steel, providing extended protection against moisture and salt intrusion, especially in coastal regions.

  • High-Speed Hot Dip Mill Galvanized Steel: For certain products, we use high-speed hot dip mill galvanizing (ASTM A653 G90), where the zinc coating ranges from 0.32 oz/ft² to 0.45 oz/ft² per side, corresponding to a thickness of 0.76 mils per side. This offers excellent protection for environments with fluctuating moisture levels or moderate corrosive elements.

  • Uniform Zinc Coating: We apply a consistent and uniform zinc coating across the entire surface of each helical pile, ensuring there are no weak spots for corrosion to initiate. This uniformity maximizes the pile’s lifespan and provides comprehensive protection, even in the most corrosive environments.

  • Galvanized Thickness Standards: Our helical piles exceed industry standards for zinc coating thickness. The thicker the zinc layer, the longer it takes for corrosion to reach the steel core, guaranteeing that your foundation remains stable for decades.

Our corrosion-resistant features are especially crucial for regions with high salt content and fluctuating groundwater levels, like the coastal areas of Long Island and Queens. Choosing our helical piles means securing your foundation against the elements, ensuring peace of mind and structural integrity for years to come.

How to Estimate the Corrosion Life of Helical Piles

The corrosion life of helical piles depends on several critical factors, each influencing how long your foundation can resist degradation. The longevity of these piles is typically evaluated by two main considerations: the life expectancy of the galvanized coating and the time it takes for the steel shaft to lose 10% of its wall thickness after the zinc coating has worn off.

 

 

Key Variables in Corrosion Life Estimation:

 

 

  • Galvanized Coating Life Expectancy: The hot-dip galvanizing process applies a protective zinc layer to the steel. This zinc layer acts as a barrier against corrosion, but over time, the coating will degrade. The rate at which this happens depends on soil resistivity, moisture, and salt content. In areas with neutral soil pH and high resistivity, like parts of Queens, the galvanized coating can last for decades.
  • Steel Shaft Corrosion: After the zinc layer wears off, corrosion begins to attack the steel itself. It’s estimated that 10% of the pile’s wall thickness must corrode before structural integrity starts to be affected. Soil conditions, moisture content, and groundwater exposure play a big role in determining how fast this occurs.
  • Soil Resistivity: Higher soil resistivity slows down the corrosion process, while lower resistivity, typically found in salty or clay-rich soils, increases it. In regions like Long Island, where saltwater intrusion can lower soil resistivity, helical piles with enhanced protection are essential.
 

In simpler terms, the corrosion life of helical piles is influenced by soil conditions, environmental exposure, and the effectiveness of the protective coatings. Understanding these factors helps in planning for long-term foundation stability.
