Kerb Stone

Kerb Stone

Kerb stones are an essential element of urban landscapes, serving both functional and aesthetic purposes. Not only do they delineate the boundary between pedestrian and vehicular areas, but they also add character and charm to our city streets.

From their humble beginnings as crude stones stacked to define road edges, kerb stones have evolved into a versatile and durable construction material with various shapes, sizes, and finishes.

In this article, we will explore the history, uses, and benefits of kerb stones, as well as the modern techniques and designs that are revolutionizing their application in urban planning and design.

What is Kerb Stone?

A kerb stone, or curb stone, is a structural element used in road construction and landscaping to create separation between a roadway and adjacent areas such as sidewalks, parking areas, and gardens.

It is typically a rectangular or square-shaped stone or concrete block placed along the edge of a pavement to prevent vehicles from driving onto pedestrian areas or gardens, and to guide rainwater towards designated drainage systems.

Kerb stones play an important role in preventing damage to sidewalks and curbs from vehicle traffic and providing a safe path for pedestrians.

In addition, they help to delineate parking areas and create a visual boundary between the road and surrounding areas.

The design and materials used for kerb stones vary depending on the specific function and aesthetic requirements of a project. The most commonly used materials include natural stone, concrete, brick, and composite materials.

Kerb stones can also be found in different sizes and shapes, with rounded, square, or sloped edges.

In road construction, kerb stones are typically installed before the laying of the road surface. The process involves excavating a trench along the road edge and filling it with concrete to create a solid foundation.

The kerb stones are then placed on top of the concrete, aligned and leveled, and secured with mortar or adhesive. In some cases, a safety kerb may be used, which features a sloped face to reduce the severity of vehicle impacts.

In landscaping, kerb stones can be used as a decorative element to add visual interest and define different areas within a garden or park.

They can be used to retain soil, create raised flower beds, or act as a border for pathways and water features.

Dimensions of Kerb Stone

As a civil engineer, I am well-versed in the dimensions and specifications of kerb stones. These important elements play a crucial role in delineating roadways, walkways, and parking areas while also providing protection and stability to adjoining surfaces.

The typical dimensions of kerb stones are dependent on their designated use and the specific requirements of a project. Generally, kerb stones are rectangular in shape and range in length from 1 to 3 feet.

The width can vary from 6 inches to 1 foot, while the height typically ranges from 6 to 12 inches.

For pedestrian and light vehicular traffic, kerb stones with a height of 6 inches are commonly used. This dimension provides adequate protection for pedestrians while allowing easy access for vehicles.

For heavier vehicular traffic, such as on highways or industrial areas, the height of kerb stones may increase to 12 inches for added strength and protection.

In addition to the dimensions, kerb stones also come in a variety of edge profiles, such as square, rounded, and beveled.

These profiles not only add aesthetic value to the overall design but also serve functional purposes, such as reducing the risk of tire damage and providing a smoother transition for vehicles.

It is important to note that the proper installation of kerb stones also plays a critical role in their effectiveness. They should be placed on a well-compact and leveled base to ensure stability and longevity.

Prices of Kerb Stone

The prices of kerb stones typically vary depending on several factors such as the type of material used, the size and shape of the stone, and the supplier.

In general, concrete kerb stones are more affordable compared to natural stone kerb stones. Concrete kerb stones can range from $3 to $10 per linear foot, while natural stone kerb stones can cost anywhere between $20 to $50 per linear foot.

The size and shape of the kerb stone can also affect its price. Standard size kerb stones, which are around 6-8 inches in height and 4-6 inches in width, are more economical compared to larger or custom-sized kerb stones.

Moreover, the supplier also plays a significant role in determining the price of kerb stones. Local suppliers may offer lower prices compared to those that import kerb stones from other countries due to the additional transportation costs.

Additionally, the cost of installation should also be taken into consideration when looking at the overall price of kerb stones. Some suppliers may offer installation services, while others may require you to hire a separate contractor, which can add to the overall cost.

Overall, the prices of kerb stones can range from $3 to $50 per linear foot, depending on various factors. It is essential to do proper research and compare prices from different suppliers to ensure you are getting the best deal for your project.

Uses of Kerb Stone

Kerb stones, also known as curb stones, are an important component in civil engineering projects. These concrete or stone blocks are used at the edge of roads, pavements, sidewalks, parking lots, and other paved areas.

They provide a physical barrier between the pavement and the surrounding landscape, as well as offering a number of other benefits. In this article, we will explore the various uses of kerb stones in civil engineering.

1. Safety and Traffic Control

One of the primary uses of kerb stones is to promote safety and control traffic flow. These blocks help to delineate between pedestrian walkways and vehicle lanes, preventing accidents and ensuring the safety of both motorists and pedestrians.

Kerb stones also assist in directing the flow of traffic by guiding drivers around curves and regulating the width of roads.

2. Drainage

Kerb stones play a critical role in drainage systems, particularly in areas with heavy rainfall. These blocks act as a barrier, preventing water from flooding pavements and roads by directing it towards storm drains.

In addition, kerb stones with a sloped top can prevent water from accumulating on the surface of roads and sidewalks, reducing the risk of accidents.

3. Stability and Durability

Due to their size, weight, and sturdy construction, kerb stones provide stability and durability to roads and other paved areas. They are designed to withstand heavy loads and can resist the impact of vehicles or other objects, making them an ideal choice for high-traffic areas.

4. Aesthetic Appeal

Kerb stones can enhance the aesthetic appeal of a landscape by adding structure and definition to a paved area. They come in a variety of sizes, shapes, and colors, allowing for customization to suit the specific needs and design of a project. Kerb stones can also be used for decorative purposes, adding visual interest to outdoor spaces.

5. Property Protection

Kerb stones are also used for property protection, serving as a protective barrier between the road and private property.

They can prevent vehicles from parking on sidewalks or encroaching on private land, ensuring that property boundaries are respected.

6. Accessibility

For people with mobility issues, kerb stones can serve as a guide for navigating sidewalks and other public spaces. They provide a detectable edge, allowing individuals with visual impairments to safely use sidewalks and crosswalks.

Kerb stones also assist wheelchair users by providing a smooth transition from the road to the sidewalk.


In conclusion, kerb stones serve as an essential element in urban and suburban design, offering both functional and aesthetic benefits. From providing a secure barrier for pedestrians and vehicles, to enhancing the overall appearance of a streetscape, kerb stones play a crucial role in creating safe and attractive communities. With a variety of materials, styles and installation methods available, these versatile structures offer endless possibilities for urban planners and designers. It is evident that the use of kerb stones will continue to be integral in the development and maintenance of modern cities and towns.
