Protecting Screw Pile Foundations in Corrosive Soil Conditions
At Blade Pile, we understand that the success of any foundation is built on durability and long-term performance, particularly in challenging environments. One of the significant hurdles in foundation construction is ensuring that screw piles withstand the impacts of corrosive soils. In the Australia & New Zealand regions we operate, soil conditions can accelerate the degradation of steel, making it essential to employ the right strategies to protect these vital structures.
With decades of experience in screw piling, we have developed a deep understanding of how to design and install foundations that are not only strong but resilient in harsh soil conditions requiring protection against the aggressive forces of moisture, salts, and chemicals. That’s why choosing the right protective coatings is critical to provide an added layer of defense against screw pile corrosion
The Challenges of Corrosive Soils
Corrosive soils can quickly degrade metal surfaces, including steel screw piles, especially in coastal and industrial environments. These soils often have high moisture levels, low pH, and aggressive chemical properties that can cause rapid corrosion of metal foundations/ This environmental challenge calls for a combination of advanced engineering and protective measures to ensure the integrity and longevity of the foundation.
According to the Australian Corrosion Association’s Impact of Corrosion in Australasia Report, corrosion in soil is influenced by various environmental factors, including soil resistivity, pH, and moisture content. Understanding these factors is crucial for construction professionals to select appropriate materials and solutions that mitigate corrosion risks in foundation systems.
Blade Pile’s Commitment to Durable Foundations
Taking a proactive approach we assess the soil properties at each site before recommending tailored foundation solutions. This includes evaluating the chemical composition of the soil, moisture levels, and other environmental factors that might contribute to corrosion. By understanding the specific requirements of the site, we are able to recommend tailored solutions that ensure both the strength and longevity of the screw piles.
By using premium-grade steel and leveraging the latest in pile installation & protection techniques, our goal is to ensure the foundation remains secure, stable, and protected for the long haul.
Steel Protective Coatings: A Key Defence Against Corrosion
To complement advanced screw piling solutions, we recognise the importance of protective coatings in extending the life of screw piles, especially in harsh, corrosive environments. Common options for protection are the application of high-performance polyurea or zinc coatings, which offer exceptional protection against corrosion, abrasion, and chemical wear.
These coatings are designed to create a seamless, durable barrier on steel surfaces, ensuring that moisture, salts, and other corrosive elements cannot penetrate the material. Offering superior adhesion and flexibility, this type of coating is ideal for steel screw piles exposed to aggressive soils and harsh environmental conditions.
As Ben Bahrami, the General Manager of Liquimix, explains, “Advanced protective coatings are formulated to offer high-level protection in the toughest environments. By applying such coatings to screw piles, you can significantly extend their service life and reduce maintenance costs in corrosive soil conditions.”
Proven Results in Real-World Applications
The success of protective coatings can be seen in numerous of our projects where screw piles have been exposed to corrosive environments. For example, in coastal regions of Queensland and Victoria where saltwater exposure is a constant concern, protective Zinc coatings have proven highly effective in preventing corrosion, ensuring that foundations remain strong and stable. Similarly, in industrial areas with high chemical exposure, the protective coating has played a critical role in extending the life of screw piles, reducing the need for costly repairs and replacements.
A great example of this in action is the Moranbah Hospital redevelopment in Queensland. Blade Pile was engaged to install galvanized screw piles at this project to combat the area’s soil conditions. The galvanization provided a protective layer against corrosion, ensuring long-term foundation stability despite the challenging environmental factors. This project demonstrates how corrosion protection strategies, like using galvanized screw piles, can help ensure a strong, stable foundation even in harsh conditions.Read more about the Moranbah Hospital project here.
