Kerbstones (Curve Stones) are durable precast concrete elements used to define road edges, support pavement stability, and separate pedestrian and vehicular areas. They help prevent paver movement, improve drainage efficiency, and enhance the overall safety and appearance of roads, pavements, and infrastructure projects.
Kerbstones are manufactured by molding a concrete mix of cement, aggregates, and water using vibration or hydraulic compaction techniques. The units are then cured to achieve durable and precision-finished road edging solutions.
Available Sizes
Our precast kerbstones are manufactured in durable standard dimensions suitable for road edging, pavement support, and infrastructure projects.

Cost-Effectiveness & Financial Savings
While kerbstones are often considered a minor component in overall project costs, choosing high-quality precast units delivers substantial long-term savings. Their durability, reduced maintenance requirements, and faster installation significantly lower lifecycle costs compared to conventional alternatives.
Zero Curing Costs
Pre-cured units eliminate on-site water and curing costs.
Labor Efficiency
Faster installation with minimal manpower
High Durability
Crack-resistant and impact-resistant with long service life
Product Scope
The product scope covers the manufacturing and supply of high-performance precast kerbstones designed for structural durability, precision alignment, and long-term infrastructure reliability. These kerbstones are produced using high-strength vibrated concrete (M-30 to M-40 grade) in a controlled factory environment, ensuring uniform quality, zero internal voids, and a smooth, defect-free finish suitable for demanding road and landscape applications.
The range includes multiple kerbstone profiles such as Full Batter, Half Batter, and Flush Kerbs, catering to diverse use cases including main roads, parking entries, and pedestrian crossings. Each unit is engineered for low water absorption (<5%), high compressive strength (>30 N/mm²), and precise dimensional tolerance (±2 mm), enabling seamless installation, efficient water channeling, and resistance to impact, weathering, and chemical exposure.
Kerbstone Types:
Our precast kerbstones are available in multiple profiles to suit different functional and site requirements. Each type is designed to ensure proper edge support, accessibility, and durability across various road and landscape applications.
1. Full Batter
Ideal for main internal roads
2. Half Batter
Suitable for parking entries and vehicle access
3. Flush Kerbs
Used for pedestrian crossings and ramps
Unique Contractor Advantages
Precision Alignment
Standard sizes (300-600 mm) ensure straight lines and uniform curves, unlike manual formwork.
Customization for Branding
Natural grey finish with chamfered edges for a clean and premium appearance.
Immediate Backfilling
Kerbs can be haunched and followed by sub-base work without waiting for curing.
Key Features Of The Product
Precast kerbstones are engineered to deliver superior edge stability, efficient drainage, and long-term durability, making them an essential component for modern road and landscape infrastructure.
- High-strength precast concrete (M-30 to M-40) ensures excellent load-bearing capacity and resistance to impact.
- Precision manufacturing with vibro-compaction guarantees uniform dimensions, smooth finish, and zero internal voids.
Structural Utility
Kerbstones play a critical role in maintaining the integrity and performance of road infrastructure by providing essential edge support, drainage control, and safety separation.
- Guides water flow toward drainage systems.
- Protects sub-base from water damage.
- Edge restraint prevents lateral movement of paver blocks.
- Creates a clear boundary between vehicles and pedestrians.

The Convincer
A road without a strong kerbstone is like a structure without a foundation—no matter the investment in asphalt or pavers, weak edges lead to early failure. Precast kerbstones act as the structural frame of the road, providing essential lateral restraint that keeps interlocking surfaces intact under heavy loads. Manufactured in controlled environments using high-frequency vibration, they ensure consistent strength (M-30+) and a flawless finish, eliminating the variability of on-site construction.
Their rapid installation process removes curing delays, allowing immediate backfilling and faster project completion. Designed for efficient water management, they channel surface runoff toward drainage systems, preventing sub-base damage and potholes. Additionally, they offer long-term sustainability by being reusable and relocatable, while enhancing safety and visual appeal through precise alignment, smooth curves, and customizable finishes.
