curbstones

Curbstones, also known as kerbstones, are large stone blocks that form the border between a road or pavement and a verge or sidewalk. Traditionally, they were quarried from granite or sandstone, but modern curbs are often made from concrete. Their primary function is to delineate the edge of the carriageway, preventing vehicles from driving onto the adjacent land and providing a physical barrier for pedestrians.

The shape and profile of curbstone vary depending on their intended use and location. Some are rectangular and set flush with the road surface, while others have a more pronounced rounded or angled profile. These different profiles can assist with drainage by directing water away from the road and into a gutter system. In some urban environments, curbstones are also designed with tactile paving features to alert visually impaired pedestrians to the edge of the sidewalk.

Historically, curbstone construction was labor-intensive, with individual stones being carefully shaped and fitted. Today, pre-cast concrete sections are commonly used, allowing for faster installation and a more uniform appearance. The durability of curbstone is a key factor, as they are subjected to significant wear and tear from vehicle traffic, weather conditions, and de-icing salts. Their presence is a fundamental element of urban infrastructure, contributing to road safety, traffic management, and the aesthetic design of public spaces.
