ICC-ES AC358 addresses the corrosion protection of steel helical piles by establishing specific mandates for material thickness and coatings based on three distinct soil corrosivity categories. These requirements ensure the structural integrity and long-term durability of the foundation in various environmental conditions.
The protection strategies for each category include:
By following these thresholds, the AC358 standard ensures that helical piers resist section loss over time, preserving the load path from the structure to the bearing stratum.
Repairing stair-step cracks in brick veneer involves a two-step approach: addressing the underlying structural movement and sealing the visible damage. Because these cracks are typically caused by foundation settlement into expansive soils, it is critical to stabilize the structure before…
Distinguishing between settlement and shrinkage cracks is essential for determining the structural health of a home. These two types of cracks have different causes and implications for your foundation: While shrinkage cracks can often be addressed with routine patching or…
No, stair-step cracks should never be ignored. While minor hairline cracks are sometimes cosmetic, stair-step patterns are among the most telling signs of foundation problems and often indicate underlying settlement. Why You Should Address Them Stair-step cracks typically develop when…
Yes, stair-step cracks in brick are one of the most distinctive and telling signs of foundation settlement or sinking. These diagonal fractures follow the mortar joints in a zigzag pattern, signaling that the underlying foundation is settling or moving unevenly.…
Understanding the difference between these two warranties is essential for protecting your construction investment. While they often work together, they cover different aspects of a project and are provided by different parties: Key Comparisons Professional inspections by a structural engineer…
