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.
