The corrosion resistance standards for foundation repair brackets are established by the International Code Council (ICC) and ASTM International. These standards ensure the long-term integrity of brackets exposed to soil moisture, varying pH levels, and chemical compounds.
Key requirements include:
- ICC Building Code Compliance: According to IBC Section 1808.8, steel elements in soil must have a protective coating or sacrificial thickness to maintain structural capacity for their intended design life.
- AC358 Acceptance Criteria: Specified for helical pile systems, this criteria mandates that brackets in ground contact must resist section loss from corrosion.
- ASTM Galvanization Standards: The industry-accepted method for meeting these codes is hot-dip galvanizing to ASTM A123 or ASTM A153. These standards define the minimum requirements for coating thickness and performance.
- Engineering Considerations: Corrosion allowances are factored directly into underpinning bracket load capacity calculations. In aggressive environments, such as coastal installations or contaminated fill, standard galvanizing may be supplemented with epoxy overcoats or high-performance paint systems.
