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.
Helical piers are an ideal foundation solution for municipal boardwalk projects due to their efficiency and minimal environmental impact. According to RMSSCO, there are several key reasons to use them for these types of infrastructure projects:Minimal Environmental Disturbance: The rotary…
Inadequate soil compaction leads to structural failure because it leaves physical gaps in the ground that cannot support the weight of a building. According to the provided content, this process involves the following mechanisms:Creation of Voids: When fill or backfill…
Foundation repair is common on the Colorado Front Range primarily due to the region’s unique and aggressive soil conditions. The area is home to some of the most volatile expansive clay soils and bentonite clay in the country, which create…
A geotechnical report is a critical requirement for foundation repair because it provides the engineering data necessary to design a safe, stable, and code-compliant structural support system.Key reasons you need this report include:Code Compliance: Many local building codes in the…
You should contact a professional foundation repair expert or a licensed structural engineer as soon as you discover a horizontal foundation crack. Unlike vertical cracks, these are serious structural red flags that signal your foundation wall is bowing inward under…
