Concrete Curb & Gutter Calculator — m, m³
How to use this calculator
Choose a curb profile type — barrier (vertical face), mountable/rollover (sloped), or straight curb with gutter pan. Enter total run length, curb and gutter dimensions using the unit dropdown (m, cm, mm). Select your currency below.
Cost — ready-mix per m³, 50 kg bags, or 25 kg bags.
Reinforcement — continuous longitudinal bars (Ø10 or Ø12) running the full curb length per EC2 §9.5.
Labor — rate per linear meter, per m³, or flat price.

How to Calculate Concrete for Curb and Gutter (Metric)
This calculator estimates concrete volume for three common curb and gutter profiles: barrier (vertical face), mountable/rollover (sloped face), and straight curb with gutter pan. Enter run length, curb height (typically 15 cm), curb width (15 cm), gutter pan width (30–60 cm), and gutter thickness (10–15 cm). Choose units (m, cm, mm) from the dropdown.
Formulas
Barrier: Area = Curb Height × Curb Width + Gutter Width × Gutter Thickness.
Mountable: Area = ½ × Curb Height × Curb Width + Gutter Width × Gutter Thickness.
Straight: Area = (Curb Height + Gutter Thickness) × Curb Width + Gutter Width × Gutter Thickness.
Volume = Area × Length × (1 + Waste%). Density: 2 400 kg/m³.
Reinforcement per EC2
Continuous longitudinal bars (Ø10 or Ø12) for crack control. Lap splices at 40db per EN 1992-1-1 §8.7. Standard bar length 6 m or 12 m. Expansion joints every 6–10 m.
