Kerb Stone Specifications

Some standards must be met when choosing, designing, and installing kerb stones. The specifications for kerb stones can vary depending on the application, location, and traffic load. By following these specifications, you can ensure that your kerb stones are strong, durable, and fit for their intended purpose. Here are the essential Kerb stone specifications that you need to consider when selecting kerb stones.

Materials Selection

The first step in kerb stone specification is selecting the correct materials. The most common materials used in kerb stone construction are concrete, granite, and natural stone. Each material has its cons and pros, and the selection will depend on the specific needs of your project.

Size and Shape

Kerb stones are available in a variety of kerb stone sizes and shapes. The shapes of Kerb stones include rectangular, quadrant, and half-battered. The kerb stone size in India you choose will depend on the application and the load-bearing capacity required. Rectangular kerbs are typically used in low-traffic areas. While half-battered and quadrant kerbs are ideal for high-traffic areas.

Kerb Stone Dimensions

When it comes to standard kerb stone dimensions, there are specific guidelines that you need to follow. The length, width, and height of kerb stones can vary depending on the application. The height of kerb stones ranges from 100mm to 250mm, while the width can vary from 150mm to 300mm. The length of kerb stones ranges from 600mm to 1200mm.

Kerb Stone Texture

The texture of kerb stones is essential for providing adequate skid resistance. The surface of the kerb stone should be rough enough to prevent slipping but not so rough that it causes discomfort to pedestrians. Texture can also vary depending on the material you will use.

Kerb Stone Color

The color of kerb stones can vary depending on the type of stone and its location. Concrete kerb stones are typically gray, while natural stones like granite, limestone, and sandstone come in a wide range of colors.

Kerb Stone Surface Finish

The surface finish of kerb stones can vary depending on the type of stone and its application. The most common surface finishes are smooth, flamed textured, exposed aggregate, bush-hammered, and sandblasted. Smooth finishes are ideal for areas where there is heavy pedestrian traffic. But textured or exposed aggregate finishes provide a better grip for vehicles.

Load-Bearing Capacity

The load-bearing capacity of a kerb stone is an essential consideration. It determines the maximum weight that the kerb stone can support without cracking or breaking. The load-bearing capacity of a kerb stone is usually measured in kN (kiloNewtons), and it can vary depending on the type of kerb stone and its thickness.


Proper installation is critical to ensure the longevity and effectiveness of the kerb stones. Hence you must follow these steps to ensure a successful installation:

  • The first step you should take is to excavate the area where the kerb stones will be installed. The depth of the excavation should be at least 300mm to provide a stable base for the kerb stones.
  • The base should be compacted and leveled to ensure a stable foundation for the kerb stones. You can add a layer of crushed stone or gravel to provide additional stability.
  • Apply a bed of mortar to the base of the excavation to provide a stable surface for the kerb stones. Make sure to apply the mortar evenly, with a thickness of approximately 25mm.
  • The kerb stones should be placed on the bed of mortar, with a gap of approximately 10mm between each stone. The stones should be leveled and secured in place with additional mortar.
  • Once you have installed kerb stones successfully, you must backfill and compact the area around them. Also, apply a final layer of mortar to fill any gaps between the kerb stones.


Proper maintenance is essential to ensure the longevity and safety of kerb stones. Here are some essential maintenance guidelines that you need to follow.

Regular Cleaning

Kerb stones should be regularly cleaned to remove dirt, debris, and any vegetation growth. You can use a pressure washer to clean the kerb stones effectively.


Any damage to the kerb stones should be repaired immediately to prevent further deterioration. Cracks, chips, or any other damage can be repaired using a suitable repair material, such as epoxy resin.


The mortar joints between the kerb stones can deteriorate over time, which can compromise the stability of the kerb stones. Re-pointing the joints with fresh mortar can help restore the stability of the kerb stones.

Wrap up:

Kerb stones are an essential component of road and pavement construction. Selecting the right type of kerb stone is crucial to ensure durability and safety. By following the specifications and installation guidelines , you can make informed decisions. It will also ensure that your kerb stone meets the required standards and are fit for purpose.
