A kerb machine is specialised construction equipment used to lay concrete or asphalt curbing efficiently and uniformly. It automates the process of forming continuous kerbs along roadsides, parking lots, and other infrastructure projects. These machines can create various kerb profiles, such as barrier, mountable, and channel kerbs, depending on the requirements of the project. Kerb machines are highly valued for their ability to produce consistent and durable kerbs quickly.

A concrete kerb machine works by extruding concrete through a mould to form a specific kerb shape. The machine is fed with a concrete mix, which is then forced through the mould using an auger or similar mechanism. As the machine moves along the designated path, it leaves behind a perfectly shaped kerb. The process includes vibrators to remove air pockets and ensure a smooth finish. This method allows for continuous kerbing with minimal manual intervention, resulting in high efficiency and uniformity.

The width of a kerb machine varies based on the model and the type of kerb it is designed to create. Typically, kerb machines can range in width from about 0.6 metres to 1.2 metres. The specific width required depends on the project specifications and the desired kerb profile. It's essential to choose a kerb machine that matches the width and profile requirements of your project for optimal results.

The thickness of a concrete kerb generally ranges from 100 mm to 150 mm, depending on the specific application and design requirements. For standard roadway kerbs, a thickness of about 150 mm is common to ensure durability and strength. The thickness can vary based on factors such as the expected load, environmental conditions, and local regulations. Ensuring the correct thickness is crucial for the longevity and performance of the kerb.

The life expectancy of a concrete kerb typically ranges from 20 to 30 years, depending on various factors such as the quality of materials used, environmental conditions, and maintenance practices. High-quality concrete mixes and proper installation techniques can enhance the longevity of the kerb. Regular maintenance, such as cleaning and repairing minor damages, also plays a significant role in extending the life of concrete kerbs.

The drying time, or curing time, for a concrete kerb can vary based on the weather conditions and the specific concrete mix used. Generally, a concrete kerb can take 24 to 48 hours to set sufficiently to handle light foot traffic. However, it usually requires at least 7 days to reach a significant portion of its strength and up to 28 days to fully cure and achieve maximum durability. Proper curing practices, such as keeping the concrete moist, are essential during this period to ensure optimal strength and longevity.

Yes, kerbing machines can install curved kerbs, but the minimum radius of the curve depends on the machine type, mould design, and kerb material. Modern slipform kerbing machines are particularly effective for gentle to moderate curves.

Key points about curved kerb installation

• Machine capability: Some machines have adjustable moulds or steering to follow curved layouts
• Curve radius: Tight curves may require smaller, specialised machines or manual adjustment
• Material flexibility: Concrete mix and consistency affect the ability to form smooth curves
• Site preparation: Accurate stringlines or guide markers ensure the kerb follows the intended alignment

With proper planning and equipment, kerbing machines can produce consistent, smooth curved kerbs for roads, pathways, and landscaped areas.

Yes, kerbing machines require trained operators to ensure accurate, safe, and efficient installation of kerbs. Operators control the machine’s speed, steering, and concrete flow.

Key points about kerbing machine operation

• Training: Operators must understand machine controls, mould adjustments, and concrete consistency
• Guidance: Operators ensure the kerb follows the correct alignment and gradient
• Safety: PPE and awareness of moving machinery and concrete hazards are essential
• Quality control: Skilled operators monitor surface finish and joint formation during installation

Using trained operators ensures kerbs are laid straight, level, and to the desired specification, reducing the risk of defects or material waste.

The production rate of kerbing machines depends on machine type, kerb profile, concrete mix, and site conditions, but modern slipform kerbing machines are designed for efficient, continuous operation.

Typical kerbing machine production rates

• Standard road kerbs: Approximately 50–150 m per hour

• Complex profiles or tight curves: Rates may reduce to 20–80 m per hour

• Factors affecting speed:

  • Concrete consistency and workability
  • Site preparation, stringline accuracy, and obstacles
  • Operator experience and machine maintenance

Production rates are higher on straight sections with well-prepared sites and consistent concrete supply, while curves or intricate profiles require slower operation for precision.
