Assumes ~0.45 ft³ per 60-lb bag and ~0.60 ft³ per 80-lb bag. Add 5–10% waste.
Tips
- Add 5–10% extra for waste and uneven ground.
- Confirm local building codes for thickness and reinforcement.
- Choose 60lb or 80lb bags based on handling preference.
Curb & Gutter Notes
- Dimensions may vary by city or project—always check local curb and gutter standards or engineer drawings.
- This calculator uses a rectangular approximation; rounded edges and slopes slightly reduce actual volume.
- Include extra concrete for waste, trimming, and possible over-excavation during forming.
- Plan expansion joints and proper drainage slope to prevent cracking and water buildup.
Curb & Gutter FAQ
Q1How do I calculate concrete for a curb and gutter?›
Multiply curb depth × curb height + gutter width × thickness, then × length. The curb & gutter calculator automates this formula.
Q2What is the standard curb and gutter size?›
Typical residential curbs are 6 inches high with a 12–18 inch gutter. Dimensions vary by municipality and road type.
Q3Do curbs and gutters require reinforcement?›
Yes, many designs include rebar or wire mesh to prevent cracking. The calculator gives volume only; reinforcement depends on code.
Q4How many cubic yards of concrete are needed for 100 feet of curb?›
It depends on dimensions. For example, a 6-inch curb with 12-inch gutter may require ~3 cubic yards. The calculator gives exact values.
Q5Should I add waste allowance when pouring curbs?›
Yes, always add 5–10% extra for form leakage, over-pouring, and finishing. The calculator recommends this addition.
