A kerb is a key element of any road – a solid support that holds the edges of the road together, clearly delineates space for cars and pedestrians, and ensures safety. It separates the road from lawns, pavements, or other areas and prevents vehicles from straying off the designated path. It helps protect the road edges from disintegration, maintains the stability of the road structure, and extends its lifespan. It also directs rainwater drainage to prevent puddles from forming on the road surface.

Visually, it also serves as a clear boundary interface: “Here’s the road – no further.” The standard natural surface ensures a subtle appearance that easily blends into any environment. Where there is a road, there is also a firmly marked edge. And that edge is held by the kerb.
