What Are the Different Types of Concrete Kerbs?

Building a road is a complex and expensive undertaking that involves careful planning, skilful construction, and the right materials. One of the most important aspects of any roadway is its kerbing. Knowing what your options are can help you build the best road possible. So, what are the different concrete kerbing options available, and how can you choose the right one for your project? 

Straight Kerb

The most basic type is known as a straight kerb. As its name implies, this type is characterised by its linear design, which helps create an even surface along the edge of a roadway. Straight kerb is often used in areas where speed limits are low or in areas where aesthetic considerations are not as important. It can also be used on highways and motorways to create a transition between lanes or differentiate between high-speed lanes and low-speed access roads.

Angled Kerb

Angled kerbs, also known as "skew" kerbs, are designed with an angled face that slopes towards the centreline of the roadway. This design helps divert water away from the traffic lane while providing additional protection against errant vehicles straying off-course. Angled curbs are often used on highways where higher speeds necessitate greater levels of safety.

Offset Kerb

Offset kerbs feature two parallel faces, with one side slightly higher than the other, creating a "step" effect that helps guide drivers back onto the road when they stray too far off course. Offset kerbs are commonly used on highways where drivers may need assistance in orienting themselves at high speeds or during inclement weather conditions.

Combination Kerb

Finally, a combination kerb combines elements from all three types mentioned above into a single unit. It offers both aesthetic appeal and increased safety for motorists. Combination kerbs are typically made up of angled faces combined with offset steps which provide both visual cues and physical barriers to help keep drivers on track during their journey.

These are some of the different types of concrete kerb available when building a road. Each has its own advantages depending on your needs and preferences. So, if you're involved in road development and planning the best layout for a particular sequence of roads, you'll want to work with a contractor who specialises in this type of civil engineering work. Get in touch with an expert organisation for further advice, and they will help you to choose the right type of concrete kerb.
