Typical pier spacing ranges from 6-12 feet depending on the load requirements and building type. For most residential structures, 8-foot spacing is common. Consult with a structural engineer for specific load calculations.
Pier diameter typically ranges from 8-24 inches. Larger diameters provide more bearing capacity but require more concrete. 12-inch diameter piers are common for most residential applications.
Pier depth depends on soil conditions and local building codes. Typically 2-4 feet deep, but may need to go deeper in areas with poor soil or frost concerns. Check local building codes for minimum requirements.
Yes, it's recommended to order 5-10% extra concrete to account for variations in hole size, spillage, and measurement errors. Having slightly more is better than running short during the pour.
This calculator is specifically designed for pier foundations. For slab foundations, footings, or other foundation types, different calculations and considerations apply.
Concrete costs vary by location, quantity ordered, delivery distance, and current market prices. Additional costs include delivery fees, pumping if needed, and labor for installation.
Most pier foundation projects require building permits and inspections. Check with your local building department for specific requirements and to ensure compliance with local codes.
