Frequently Asked Questions
What’s the formula for concrete calculation?
Volume = Length × Width × Depth (converted to feet). Waste percentage is added to account for spills and finishing.
How thick should concrete be for driveways?
4 inches is standard for passenger vehicles, 5-6 for heavy trucks. Commercial applications may require 6-12 inches.
How do I convert to cubic yards?
One cubic yard = 27 cubic feet (3ft × 3ft × 3ft). Our calculator automatically converts to the most appropriate unit.
Why include a waste factor?
Concrete delivery involves inevitable losses from spillage, form adjustments, and finishing. 5-10% is typical industry allowance.
What is ready-mix concrete?
Concrete mixed and delivered in a ready-to-use state. Common for projects needing more than a few cubic yards of material.
