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.
Fixing horizontal foundation cracks requires professional, engineered solutions because these cracks signal that the wall is bowing inward under extreme lateral pressure. Unlike minor surface cracks, horizontal fractures compromise structural integrity and cannot be fixed with simple cosmetic repairs.According to…
The cost of adding an egress window to a basement in Colorado typically falls within two general price ranges depending on the specific scope of the project: Factors Influencing the Final PriceSeveral variables can increase or decrease the total cost,…
Based on the provided documentation, a structural engineer charges a fixed fee for an inspection report. Unlike a general contractor who provides a repair estimate, the structural engineer’s fee covers a diagnostic forensic evaluation and the delivery of a sealed…
The cost of repairing a bowing basement wall in Denver varies depending on the severity of the damage and the specific repair method chosen. Because Colorado’s expansive clay soils and climate create unique structural challenges, Rocky Mountain Steel Piering utilizes…
Rocky Mountain Steel Piering does not publish a flat per-foot rate for helical pier installation. Because every property in the Denver Metro and Front Range region has unique subsurface conditions, costs are provided through custom quotes following a thorough on-site…
