How to use it
Enter slab thickness
Most patios and walkways use 4 inches. Driveways and load-bearing work may need more.
Order with waste
Use the 10% waste recommendation to cover spillage, uneven subgrade, and small measurement errors.

FAQ
Concrete estimating questions
How does the gravel calculator work?
Enter the project dimensions and the calculator converts them into material quantities using common construction estimating formulas.
Should I add waste?
Yes. Most material orders should include a waste allowance for cuts, spillage, uneven base, and field measurement variation.
Are these results final construction advice?
No. Use these estimates for planning, then verify product yield, local code, structural requirements, and supplier recommendations.
