A kerb stone When you walk along a road On the kreb stone, footpath, or landscaped garden, you’ve probably noticed the boundary stone that separates the road from the pedestrian walkway. That boundary is known as a kerb stone (or curb stone, depending on the region). It plays a crucial role not only in road safety but also in the aesthetics and structural support of pavements.
In this blog, we’ll answer the most asked questions about kerb stones, their uses, sizes, installation, and maintenance.
What is a kerb stone?
A kerb stone is a rectangular concrete or stone block used to create boundaries between the road and footpath, parking areas, gardens, or landscaped zones. It provides strength to the pavement edge and prevents road edges from breaking.
Is it curb or kerb stone?
The difference lies in regional spelling:
- In British English, it’s written as kerb stone.
- In American English, it’s written as curb stone.
Both terms mean the same thing.
What is kerb vs curb?
- Kerb → British spelling (used in India, UK, and most Commonwealth countries).
- Curb → American spelling (used in the USA and Canada).
So, kerb vs curb is purely a matter of spelling preference.
How thick is a kerb stone?
A kerb stone is typically 100 mm to 150 mm thick, depending on road design and traffic load requirements.
What is the use of kerb?
The use of kerb is to:
- Provide safety to pedestrians.
- Define the edge of the road.
- Prevent vehicles from leaving the carriageway.
- Control rainwater flow toward drainage.
What is kerb height?
The curb height is the vertical distance between the road surface and the top of the kerb stone. Normally, it ranges from 100 mm to 200 mm, depending on design standards.
What is a kerb wall?
A curb wall is a small retaining structure made of kerb stones or concrete to support pavements, prevent erosion, and guide surface runoff.
How are kerb stones installed?
The steps for kerb stone installation include:
- Excavation and preparation of the base.
- Laying a cement concrete foundation.
- Aligning kerb stones in position.
- Filling joints with mortar.
- Backfilling and compacting around the stones.
Do kerbstones prevent erosion?
Yes, kerbstones prevent soil and road edge erosion by holding the pavement together and directing water toward drains.
What are common uses for kerb?
Common uses for kerb include:
- Road safety boundaries.
- Parking lot demarcations.
- Footpath and garden edging.
- Drainage channel guidance.
What is a normal kerbstone?
A normal kerbstone generally has a standard size of 300 mm (height) × 150 mm (width) × 1000 mm (length).
What is the weight of kerb stone?
The weight of curb stone depends on size and material. A standard concrete kerb stone weighs between 35 kg to 45 kg.
Why is kerb stone used?
Kerb stones are used to:
- Protect road edges.
- Provide structural support.
- Improve the aesthetics of pathways.
- Safeguard pedestrians.
What is the HSN code for kerb stone?
The HSN code for kerb stone in India is 68029300, which falls under “worked monumental or building stone.”
How to cut a kerb stone?
Kerb stones can be cut using:
- A stone-cutting machine.
- An angle grinder with a diamond blade.
- Chiseling for small adjustments.
What is the purpose of a kerb stone?
The purpose of a kerb stone is to ensure safety, durability, drainage control, and aesthetic boundary marking in road and landscape construction.
What is the difference between kerb and kerb stone?
- Kerb → Refers to the raised edge along the road.
- Kerb stone → The physical concrete or stone block used to construct the kerb.
How do you maintain kerb stones?
Maintenance of kerb stones includes:
- Regular cleaning.
- Replacing broken or displaced stones.
- Repainting for visibility.
- Checking drainage flow.
Can you paint kerb stones?
Yes, kerb stones can be painted (commonly in black and white stripes or yellow and black). This improves visibility for drivers and enhances road safety.
Conclusion
A kerb stone may seem like a simple roadside element, but it plays a vital role in road safety, drainage control, pedestrian protection, and overall road aesthetics. Whether you call it kerb or curb, its purpose remains the same: to provide strength, function, and structure to roads and pathways. Proper installation, maintenance, and use make kerb stones an essential component of urban infrastructure.
