For decades, contractors faced three choices when it came to pouring curb and gutter: using a large slipform machine, setting a face form, or shaping it entirely by hand with a darby. Each option had its drawbacks— either too expensive, too labor-intensive, or simply not effective. That’s exactly why the CM4000 Curb Roller was created. To provide a smarter, more effective way to get the job done.
Built by Contractors, for Contractors
The CM4000 wasn’t designed in a boardroom— it was built by someone who actually understood the frustrations of curb and gutter work. The goal was to increase production, reduce labor demands, and ensure a high-quality finish. Unlike traditional methods, the Curb Roller offers versatility without the high up-front cost of slipform machines or the demanding back-breaking labor of hand forming.
From day one, contractor input has shaped the evolution of this tool. That’s why today, the Curb Roller supports over 30 stocked profiles (as well as custom) in various shapes and sizes with fast turnaround times. Whether the job calls for standard curb and gutter, a shorter profile, a monolithic pour, or even a sidewalk application, this machine is designed to adapt.
Versatile Configurations for Every Job
A big advantage of the CM4000 is its adaptability. Here’s how it adjusts to different project needs:
- Sidewalk Kit: Expands the machine’s capabilities, allowing it to function as a roller screed for sidewalk pours and small flumes up to six feet wide and 6 inches in depth.
- Short Profile: A more compact version, perfect for jobs that require a tighter curb-to-gutter ratio.
- Standard Profile: Can pour curb and gutter up to 32 inches wide and 6 inches in height, covering most general applications.
- Monolithic Kit: Designed for jobs where the curb is poured as part of the slab, common in parking lots, street, and storage unit applications.
How It Works in the Field
The CM4000 requires a hydraulic power source and comes equipped with large flat face couplers and a 25-foot hydraulic hose with protective cloth wrapping. It commonly connects to a skid loader, mini excavator, or any other machine with auxiliary hydraulic power. A built-in flow control block ensures the machine operates at the correct pressure— 5 GPM at 2200 PSI —so it runs efficiently while protecting both the Curb Roller and the pump machine.
A few key features make the CM4000 user-friendly on the job site:
-
-
- Lifting Points & Auxiliary Handles: Designed for easy transportation and maneuverability, especially in tight spaces.
- Directional Valve with Neutral Tab: Allows precise control of drum speed and reversible direction while keeping safety at the forefront.
- Operator’s Belt: Helps distribute the weight, making it easier to guide the machine along the forms without putting strain on the operator’s arms, shoulders, and back.

Durable Construction & Long-Term Performance
Made from 3/16” steel, the CM4000’s drums are built to last, typically with a minimum lifespan of 30,000 linear feet before showing significant wear. The most intense wear happens on the gutter side, where the drum meets the form. However, the guide ring shields the drum from wear and extends the drum’s lifespan while maintaining precision and finish quality.
Contractors working in multiple regions know that curb and gutter profiles vary widely, usually from one city to the next. That’s why Curb Roller Manufacturing offers custom drum fabrication. Whether a job requires a standard profile or something unique, the CM4000 can be outfitted to match virtually any curb and gutter specification up to 6 inches high and 6 feet wide.
Expanding Possibilities with Customization
Beyond curb and gutter, the CM4000’s ability to handle custom drum designs means it can be used for flumes, specialty curbs, and other niche concrete applications. While large slipform machines dominate major highway projects, they aren’t always practical for smaller-scale or specialized work. That’s where a machine like this fills the gap by providing cost-effective efficiency without sacrificing adaptability.
For contractors who frequently tackle monolithic curb and gutter, the monolithic kit broadens capabilities even further. And for those working beyond the CM4000’s six-foot limit, options like the CM4100 or a fully custom-built solution can take efficiency to the next level.
A Smarter Approach to Curb and Gutter Work
With labor shortages, tight deadlines, and job site challenges, efficiency and durability matter more than ever. The CM4000 is more than just a machine— it’s a practical solution for contractors looking to improve production and job quality without adding unnecessary complexity.
By listening to contractors and continuously refining its capabilities, the CM4000 delivers a tool that works as hard as the crews using it. Whether it’s streamlining curb and gutter work, expanding into monolithic pours, or taking on custom projects, this machine makes it easier to get the job done right the first time.
