Metric Concrete Curb & Gutter Volume Calculator
This calculator determines the cross-sectional area and concrete volume for a curb-and-gutter section when site measurements are in metres (m) and millimetres (mm). Results are provided in cubic metres, cubic feet, and cubic yards, along with running totals for multi-section estimates.

Calculator
- the horizontal run of the curb section in metres
- thickness of the curb measured from the face to the back edge in millimetres
- vertical height of the curb above the gutter slab in millimetres
- the horizontal width of the gutter beyond the curb in millimetres
- thickness of the gutter slab (flag thickness) in millimetres
Results
- the cross-sectional area of the curb face and slab in square millimetres
- the volume of concrete needed in cubic metres
- the volume in cubic yards
- the volume in cubic feet
- Running Totals: cumulative volumes for multiple sections
Curb & Gutter Formulas
Variables (all metric): \(D\) = curb depth (m), \(H\) = curb height (m), \(G\) = gutter width (m), \(T\) = flag thickness (m), \(L\) = length (m).
- Curb area: \(A_{curb}=D \times H\)
- Flag width: \(W = D + G\)
- Flag area: \(A_{flag}=W \times T\)
- Total area: \(A_{tot}=A_{curb}+A_{flag}\)
- Volume (ml): \(V_{m^{3}} = A_{tot} \times L\)
- Volume (ftl): \(V_{ft^{3}} = \dfrac{V_{m^{3}}}{0.0283168466}\)
- Volume (ydl): \(V_{yd^{3}} = \dfrac{V_{ft^{3}}}{27}\)
Worked Example
Given:
\(L = 10\,\text{m},\; D = 0.15\,\text{m},\; H = 0.30\,\text{m},\;
G = 0.40\,\text{m},\; T = 0.15\,\text{m}\)
- \(A_{curb}=0.15 \times 0.30 = 0.045\,\text{m}^2\)
- \(W = 0.15 + 0.40 = 0.55\,\text{m}\)
- \(A_{flag}=0.55 \times 0.15 = 0.0825\,\text{m}^2\)
- \(A_{tot}=0.045 + 0.0825 = 0.1275\,\text{m}^2\)
- \(V_{m^{3}} = 0.1275 \times 10 = 1.275\,\text{m}^3\)
- \(V_{ft^{3}} = \frac{1.275}{0.0283168466} \approx 45.03\,\text{ft}^3\)
- \(V_{yd^{3}} = \frac{45.03}{27} \approx 1.67\,\text{yd}^3\)
