Hey! Concerned about the longevity of metal screw piles. What should we know about corrosion and how to prevent it?

Hey! Your concern about corrosion is valid - it's one of the recognized disadvantages of pile foundations. Since metal is susceptible to electrochemical corrosion, especially when buried in soil that may contain moisture, minerals, and other corrosive elements, protection is essential for long-term durability. The best approach is to choose piles with galvanized or two-component coating from the start. Galvanizing provides a zinc layer that protects the steel underneath, while two-component coatings offer even more robust protection against chemical and moisture exposure. These protective coatings significantly extend service life - properly protected piles have a minimum service life of 80 years. Without adequate corrosion protection, however, piles can deteriorate much faster, potentially compromising structural integrity within years rather than decades. The investment in quality coatings is worth it - replacing a failed foundation is exponentially more expensive than paying for proper protection initially. When selecting piles, don't compromise on corrosion protection to save money. Ask suppliers specifically about coating types, thickness, and expected service life in your soil conditions. Some soils are more corrosive than others, so local soil chemistry matters.
