Kerbs & Channels

Precast concrete kerbs are the unsung heroes of our roads and streets, ensuring the safety of road users and pedestrians, and contributing to the paved environment over many years. It is worth reminding ourselves of their characteristics and capabilities, and how precast concrete can be specified with confidence as a tried and tested solution – unlike some other unestablished kerb materials.

Precast concrete kerbs are produced in a wide range of sizes and radii with coloured, textured and profiled surfaces. They are manufactured using three main processes: semi-dry, hydraulically pressed and wet cast. The majority of precast concrete kerbs are produced by hydraulic pressing, with some very specialist kerb components wet cast. Secondary processes can provide different surface finishes, some of which provide a close match to traditional stone. These are particularly useful for the cost-effective edging to roads and footways in historic towns and conservation areas.

The full range of British Standard profiles and components is available from Interpave members but the choice of alternatives to suit particular applications continues to grow. Concrete kerbs with integral drainage facilities are widely available and small element kerbing units, similar in size and material to paving blocks, provide added flexibility: use the Manufacturer Members link above for more details. Special kerbs – for example to contain vehicle wheels or improve accessibility onto buses – have also been developed.
