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.
Poor drainage is a leading contributor to foundation settlement because it disrupts the stability of the soil supporting a structure. When water is not properly routed away from a home, it saturates the ground, leading to two primary destructive processes:Soil…
Hydrostatic pressure occurs when the soil surrounding a foundation becomes saturated with water from heavy rainfall, melting snow, or poor drainage. This water fills the voids between soil particles and exerts a powerful lateral (outward) force against the foundation walls.According…
