Concrete Driveway Thickness Standards
Driveway thickness must match the loads it will carry. Too thin, and it cracks under heavy vehicles. Too thick, and you're wasting money. This guide covers the standards for different vehicle types.
Passenger Cars: 4 Inches
Four inches is standard for passenger vehicles:
- Cars, SUVs, light trucks
- Standard residential traffic
- Most common thickness
Heavy Trucks/RVs: 6 Inches
Six inches is required for heavy loads:
- Large RVs
- Heavy trucks
- Commercial vehicles
- Prevents cracking under weight
Always Use 4000 PSI Mix
Regardless of thickness, always use 4000 PSI concrete:
- Handles freeze-thaw better
- Supports heavy loads
- Lasts longer
- Worth the small cost difference
The Bottom Line
4 inches for passenger cars, 6 inches for heavy trucks/RVs. Always use 4000 PSI mix regardless of thickness. These standards ensure your driveway handles the loads it will face.
