In Nebraska, building codes generally require deck footings to be placed at a specific depth to prevent damage from frost heave. According to the International Code Council (ICC) digital building codes, the requirements are as follows:
- Minimum Depth: A minimum footing depth of 42 inches below grade is required for Omaha and much of the state of Nebraska.
- General Range: Depending on the specific local area, the frost depth may require footings to be set anywhere between 36 and 48 inches below grade.
Following these depth requirements ensures that the bearing point of the footing sits safely below the frost line, where soil temperatures remain stable and are not disrupted by seasonal freeze-thaw cycles.
While traditional concrete footings can be Used to reach this 42-inch depth, they often require extensive excavation and curing time. Helical piers are an alternative solution that bypasses these deeper, unstable soils to provide code-compliant, frost-resistant foundations without the need for traditional deep concrete pours.
