Concrete Footing Calculator

Footing Types

• Strip/Continuous: Foundation walls, long loads
• Spread/Pad: Individual columns or posts
• Combined: Multiple columns on one footing
• Wall: Basement or retaining wall foundations

Sizing Guidelines

• Width: Typically 2x wall thickness minimum
• Depth: Below frost line (varies by region)
• Thickness: Usually 8-12" minimum
• Bearing: Check soil bearing capacity

Key Considerations

• Frost depth requirements in your area
• Soil bearing capacity and type
• Building loads and occupancy
• Local building code requirements
• Drainage and waterproofing needs

Construction Steps

1. Layout and mark footing locations
2. Excavate to required depth and width
3. Level and compact soil base
4. Place forms (if needed above grade)
5. Install reinforcement
6. Pour and level concrete
7. Cure properly before loading

Important Notes

• Always check with local building dept
• Engineering may be required
• Consider soil tests for large projects
• Plan for proper drainage
• Allow proper curing time
