Kerbstone

What is a kerbstone?

A kerbstone is a durable block placed along roadsides, pavements, and gardens to:

• Separate vehicles and pedestrians
• Guide rainwater to drains
• Support road and pavement edges
• Improve safety and traffic control
• Add visual order to landscapes

Used worldwide, kerbstones are essential in roads, parking lots, gardens, and city infrastructure.

Materials Used

• Granite: Highly durable and weather-resistant; ideal for highways and cities.
• Limestone: Softer stone with a beige look; suitable for medium-traffic and decorative areas.
• Sandstone: Easy to shape, comes in warm tones; used in gardens and dry climates.
• Marble: Luxurious and polished; used for high-end projects, not ideal for heavy traffic.
• Travertine: Porous and warm-colored; great for landscape designs and light-traffic zones.
• Basalt: Dense and strong with a dark, modern look; good for urban environments.
• Concrete: Affordable and flexible; widely used in public infrastructure.
