Concrete Curb and Gutter Volume Calculator

Calculate the concrete volume needed for a combined curb-and-gutter roadway section.

Computed in your browser — nothing you enter is uploaded. Figures are presented for United States against IRC 2024, and every formula is cited under regulatory standards below.

Curb and gutter concrete volume

7.36 yd³

High confidence
Combined cross-sectional area
1.21 ft²

With the figures above, the curb and gutter concrete volume comes to 5.62 m³. Note that total run length sits at the low end of the range this calculator was checked against, so treat the output as indicative rather than settled. This is calculated for United States and cites IRC 2024. Building in another market? Change the selector above so the units and code reference follow.

Estimated cost — your price

This site holds no price list for this material — local prices vary too much to publish honestly. Enter your supplier's price and the result is costed with it.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

  • Combined cross-sectional area = (curb height × curb width) + (gutter width × gutter thickness); volume = run length × combined cross-sectional area

Frequently asked questions

Why is curb-and-gutter volume calculated as one combined section?
Curb and gutter are typically formed and poured together as a single monolithic concrete section, so the combined cross-sectional area (curb height × curb width, plus gutter width × gutter thickness) is multiplied by the run length to get one total volume for the section.
Does this account for transitions, curb returns, or driveway aprons?
No — this calculates volume for a straight run of constant curb-and-gutter cross-section only. Curb returns at intersections, driveway aprons, and any depressed or transition sections have different geometry and should be volumed separately.
What curb and gutter dimensions should I use?
Use the actual dimensions from your project's roadway standard detail — curb height, curb width, gutter width, and gutter thickness all vary by jurisdiction and roadway classification.
