Kerb stone refers to a horizontal concrete or stone block used to edge and separate sidewalks, driveways, and roads from the adjacent landscaped or grassed areas. It serves as a barrier to prevent vehicles and pedestrians from encroaching on the green space while also enhancing the visual appeal of the surrounding area. Kerb stones come in a variety of shapes, sizes, and materials, including concrete, natural stone, and granite, and can be customised to match the design and style of a specific property or area. They are widely used in urban development, commercial and residential landscaping, and road construction projects.

Kerb stone: Types of kerbs
-
Low or mountable kerbs
Class I kerbs are another name for low or mountable kerbs. The kerb stone’s main function is to direct traffic so that it stays in its lane. The height of this kerb is extremely low to make it easier for the motorist to move the shoulder region. This form of a kerb stone, which has a height of 70 to 80 mm, is ideal for the longitudinal drainage system.
