Curb and gutter machines are specialized construction equipment designed to automate the forming and pouring of road curbs, gutters, sidewalks, and other concrete boundaries. These machines improve efficiency, quality, and consistency while reducing manual labor on large-scale paving projects across highways, municipal roads, and commercial developments.
How Curb and Gutter Machines Work
These machines use a combination of a hopper to hold concrete or asphalt mix, conveyor or auger systems to deliver material, and molds defining the shape and dimensions of the curbs or gutters. The concrete is effortlessly extruded and compacted into the desired profile as the machine moves continuously along the construction path.
Hydraulic systems power the movement, mold adjustments, and material delivery components. Operator control panels allow precise adjustment of speed, height, width, and shape of the curb, while some advanced models integrate GPS or laser guidance for stringless operation, enhancing precision and productivity.
Types of Curb and Gutter Machines
Curb and gutter machines are essential for:
In the 1970s, Power Curbers revolutionized curb construction by introducing the hydraulic mold offset concept, lifting productivity and allowing operators to quickly avoid obstacles like utility covers without stopping work. Their 5700 series machines set new standards for the curbing industry and remain in demand for both new and pre-owned units thanks to their durability and ease of use.

Types of Curb and Gutter Machines
- Slipform Curb and Gutter Machines: These automated machines extrude continuous curbs or gutters with smooth, uniform finishes. They excel in large projects due to fast production rates and adaptability to various designs. Automated cross-slope controls and stringless guidance are common.
- Power Curbers: Versatile units with adjustable molds and settings for custom curb dimensions. Widely used in residential and municipal jobs, power curbers handle concrete and asphalt and maintain high-quality consistency.
- Extrusion Curb Machines: Smaller, compact machines using screw extrusion to form curbs, often ideal for confined urban areas or smaller jobs.
- Hopper: Holds and feeds concrete or asphalt mix.
- Conveyor or Auger System: Moves and mixes materials.
- Mold/Forming Plates: Shape and size the curb.
- Hydraulic System: Controls machine functions and mold positioning.
- Operator Controls: Panels for real-time adjustments.
- Mobility System: Crawler tracks or wheels for site maneuverability.
- Optional Trimmers: Prepares pavement edges before curb placement.
- Power Curbers 5700-D: Known for slipform precision, GPS integration, and hydraulic mold adjustment.
- Miller Curber Machines (MC 550, MC 650, MC 850, MC 900): Various sizes suitable for diverse curb widths with vibration and multiple auger options.
- Compact Extrusion Machines: Best for smaller or specialized applications requiring flexibility and maneuverability.
Curb and gutter machines are essential for:
- Roadway construction, shaping curbs and gutters to channel water and mark lanes.
- Parking lot boundaries and drainage.
- Landscaped garden borders and pedestrian sidewalk edges.
- Drainage ditch liners and agricultural irrigation barriers.
- Stadium, golf course, and recreational path construction.
- Barrier walls and parapets for highway safety.
- Typical curb widths range from 14 to 24 inches or more.
- Operating speeds vary from 1 to 30 meters per minute depending on machine type.
- Machine power ranges from small gasoline units (~5hp) to hydraulic diesel-driven track machines (~50-100+ hp).
- Adjustable mold heights and lateral offsets allow versatile shapes.
- Slipforming: Continuous extrusion technique forming concrete structures without joints.
- Auger Conveyor: A rotating screw that transports concrete evenly.
- Stringless Operation: Using GPS or lasers instead of guide wires for precision.
- Hydraulic Mold Offset: Enables machine to adjust mold position horizontally.
