Planning Your Concrete Driveway
A well-planned concrete driveway adds curb appeal and value to your home. The most critical factor for longevity is proper thickness and reinforcement.
Recommended Thickness
- 4 Inches: Standard for passenger cars and light SUVs. This is the most common residential specification.
- 5 Inches: Better for medium-duty use or if the subgrade is less than perfect.
- 6 Inches: Required for heavy trucks, RVs, or commercial applications to prevent cracking under load.
Cost Factors
Concrete is typically sold by the cubic yard. Prices vary by region, but generally range from $115 to $150 per yard delivered. Don't forget to budget for:
- Site preparation (excavation, gravel base)
- Formwork (lumber, stakes)
- Finishing tools (bull float, edger)
- Labor (if not DIY)
Frequently Asked Questions
How thick should a concrete driveway be?
A standard residential driveway should be at least 4 inches thick. For heavier vehicles (like RVs or large trucks), increase thickness to 5 or 6 inches.
Do I need rebar in my driveway?
Yes, reinforcement is highly recommended to prevent cracking and shifting. A grid of #3 or #4 rebar spaced 24 inches apart is standard.
How much waste should I calculate?
Always order 5-10% extra concrete to account for spillages, uneven subgrade, and settling. This calculator adds a 10% safety margin.
