Concrete Strength & Pricing Guide
Concrete prices vary based on strength requirements. Different PSI ratings (3000, 4000, 5000+) come with different costs to reflect material composition and performance characteristics.
Pricing Factors:
- • Concrete strength and mix specifications
- • Delivery distance and transportation fees
- • Minimum order quantities and service charges
For current pricing in your area, contact local suppliers or visit American Concrete Institute.

Footing Calculator FAQ
Footing depth depends on soil conditions, frost line, and building codes. Typical depths: residential footings 8-12 inches (20-30cm), commercial footings 12-18 inches (30-45cm). Always check local building codes and consider frost depth in your area.
For rectangular footings: multiply length × width × depth. For example: 20ft × 2ft × 1ft = 40 cubic feet or 1.48 cubic yards. Our calculator handles the conversion automatically.
C25 (3000 PSI) is suitable for most residential footings. Use C30 (3500 PSI) or higher for commercial footings or areas with heavy loads. Always consult with a structural engineer for specific requirements.
Most footings require reinforcement. Use rebar or wire mesh for added strength, especially for wider footings or those supporting heavy loads. Check local codes for specific requirements.
Order 5-10% extra concrete to account for waste, spillage, and slight variations in excavation depth. This calculator helps you get the base amount needed.
