Find the Best Kerb and Channel Experts Near You

Kerbs and channels are barriers typically located at the edge of roadways. The purpose of these structures is to direct stormwater into drains and prevent water from entering under road surfaces. The kerb serves as a raised barrier that separates the road from sidewalks or landscaped areas, while the gutter channel, situated next to the kerb, collects and directs stormwater runoff to drainage systems. This system is crucial in preventing water accumulation on the road, which can lead to vehicle hydroplaning and road surface damage. Kerbing and channelling are also designed to protect the edge of the road from erosion, separate the road from the roadside, and discourage drivers from parking or driving on sidewalks and lawns.

There are several processes to consider when it comes to kerb and channel construction. For example, the preparation of kerb mix or concrete requires accurate calculations. Typically, contractors use two types of kerb mixes for various edging types that include C7.5 semi-dry concrete for the bedding, and C20P concrete for the haunch with 25 to 55mm slumps.

Kerb and channel construction starts by laying out the bedding material. It is recommended to lay the bedding concrete approximately 100 to 150mm thick before compacting. The bedding material is generally a mixture of different aggregates such as sand and gravel. These aggregates are trampled to help keep the kerb in place. The sub-base must be topped-up to ensure that only 100 to 150mm of concrete bedding is used.

Next comes the laying of the kerb. The kerb is placed on top of the concrete bedding and compacted down to the required level using a rubber mallet. A string line guide is also used to indicate the level of the kerb. Accurate levelling is one of the most important parts of constructing a kerb. Kerb and channel contractors advise that a kerb should never exceed 3mm above or below the line.

The placement of the haunch comes after the kerb is placed and accurately aligned to the desired level and angle. Haunching concrete holds the kerb in the lateral side plane, which prevents the structure from being pushed out of alignment. In addition, haunching concrete helps the structure’s firmness and robustness to withstand the weight of the contained pavement and its traffic. Kerb and channel contractors then add some finishing touches to give the structure a smooth finish.

Kerb mix is a type of concrete specifically designed for the construction and maintenance of roadside kerbs. Kerb mix can also be used for different purposes where kerb and channel contractors use it for building garden edges, rolled gutters, roadworks, mountable kerbs and channels, conventional vehicle crossings and more.

A kerb and channel refer to a concrete or stone structure installed along the edge of a road. The kerb acts as a boundary between the road and adjacent areas such as footpaths, while the channel (or gutter) is a depression next to the kerb designed to facilitate water drainage from the road surface. This combination helps manage stormwater runoff, preventing flooding and maintaining the integrity of the road surface.

In Australia, there are several types of kerbs commonly used in road construction, including:

1. Barrier Kerbs: These are tall and straight, designed to prevent vehicles from mounting the kerb.
2. Mountable Kerbs: These have a sloped face, allowing vehicles to drive over them if necessary.
3. Semi-Mountable Kerbs: These are a hybrid between barrier and mountable kerbs, offering some resistance to vehicles while still being traversable.
4. Roller Kerbs: These have a rounded shape, making them easier for vehicles to cross.
5. Integral Kerbs: These are built as part of the pavement structure, often used in industrial areas for added durability.

Kerbs serve several important functions in road and urban design, including:

1. Defining Road Edges: They provide a clear boundary between the road and adjacent areas such as footpaths, cycle paths, and landscaped zones.
2. Water Management: Kerbs help channel water into drainage systems, preventing flooding and erosion.
3. Safety: They act as a physical barrier to prevent vehicles from straying onto pedestrian areas or other restricted zones.
4. Aesthetics: Kerbs contribute to the overall visual appeal and orderliness of urban streetscapes.

The primary difference between pavement and kerb lies in their function and placement:

• Pavement: This refers to the road surface that vehicles travel on. It is designed to provide a smooth and durable surface for traffic.
• Kerb: This is a raised edge along the pavement, serving as a boundary and drainage facilitator. It defines the edges of the road and separates it from other areas such as footpaths and landscaped sections.

Kerbs are essential for managing stormwater, enhancing road safety, and contributing to the structural integrity of roadways, while pavements are crucial for providing a stable and smooth driving surface.
