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. 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.
