FAQ
How do I calculate concrete for a curb?
Multiply the curb cross-sectional area by its length, add waste, then convert cubic feet to cubic yards. A trapezoid uses the average of its top and bottom widths.
Can I include a gutter pan?
Yes. Enter both gutter width and thickness. Leave both fields empty when the curb has no gutter pan.
Are standard curb dimensions built in?
No. Enter dimensions from the approved drawing or your field measurements. Curb profiles and local requirements vary.
When should I use the slab concrete calculator?
Use the slab calculator for patios, driveways, and other broad rectangular pours. Use this page for a long curb cross-section and optional gutter.
