What are Trief Kerbs?

A Trief kerb, otherwise known as a containment kerb, is a uniquely designed safety kerb used in road construction. These kerbs act as a robust and deterrent barrier, protecting pedestrians and infrastructure by preventing vehicles from mounting pavements.

These kerbs are ideal to use where it is especially important that vehicles do not mount the pavement such as areas of high pedestrian traffic or bridge crossings.

Trief Containment Systems developed this product, and since then, Trief kerbs have become a popular and effective road safety measure used all over the world.

Why Are Trief Kerbs Used?

One of the primary purposes of Trief kerbs is to improve safety on roads and pedestrian walkways. They serve as a physical barrier between vehicles and the pavement, reducing the risk of accidents from cars that accidentally mount kerbs and become a danger to pedestrians. By creating a separation between vehicular and pedestrian areas, Trief kerbs help to safeguard vulnerable road users and prevent potential collisions.

Safety Enhancement

The main reason for using Trief kerbs is to provide a safer environment. They form a physical barrier between vehicles and pedestrians, reducing the risk of accidents.

Untold damage can be caused when a car veers off the road onto the pavement. Trief kerbs can be a lifesaver for pedestrians and help prevent cars from mounting pavements.

Trief kerbs are not used as a deterrent to stop vehicles travelling head-on at a 90-degree angle, here, reinforced barriers must be used. This type of safety kerb proves highly effective in stopping cars mounting kerbs when travelling at a perpendicular angle to the roadside.

If a car has to swerve to avoid a road collision, a Trief Kerb may prevent it from veering onto public footpaths and walkways and inadvertently creating danger for pedestrians.

Aesthetic Appeal

Apart from safety, Trief kerbs also improve the visual appeal of the area where they’re installed. They come in different colours and shapes, complementing the overall design and aesthetic of the surrounding landscape. Trief kerbs are a popular choice for road construction projects aiming to create safer and more attractive environments for pedestrians and motorists alike.

How Are Trief Kerbs Installed?

The installation of Trief kerbs involves careful planning and a step-by-step process by Quinn Developments.

Pre-Installation Planning

Site Assessment

The site assessment begins with a detailed analysis of the terrain where the Trief kerbs will be installed. We consider factors such as the slope of the land and soil type and perform a drainage evaluation of the proposed kerb locations. When we lay out the kerbs, we need to ensure that they are installed on stable ground and suitable foundations are in place.

We also need to ensure that any underground utilities, such as water pipes, electrical cables, and gas lines, are identified and marked to prevent accidental damage during the installation process.

Material Selection

Trief kerbs are generally manufactured from concrete, which is highly durable and strong. Concrete can withstand heavy loads and resist damage from environmental factors such as moisture and temperature fluctuations, making it an ideal material for Trief kerbs. Trief Kerbs are wet cast from high-strength concrete, and different strengths can be adopted for various situations if the placement dictates or expects a level of frequent collision.

Installation Process

Site Preparation

The site is prepared by clearing any debris or obstacles. This includes removing rocks, branches, and other debris from the installation site to create a clean and clear workspace for our highway team.

Once any debris is removed, our team will level the ground. We will ensure proper drainage and address any uneven areas that could affect the stability of the kerbs.

Laying the Kerbs

The alignment for the planned Trief Kerbs is then marked on the ground using stakes, strings, or paint. This helps guide our installation process and ensures that the kerbs are positioned accurately according to the project specifications.

After excavation, the subbase is prepared to provide a stable foundation for the Trief kerbs. This may involve compacting the soil or adding a layer of aggregate material to improve stability and drainage.

The grade, or slope, of the kerb alignment, is carefully set to ensure proper drainage and alignment of the kerbs. Our engineers may use a laser level or other surveying equipment to achieve the desired slope and elevation.

Finishing Steps

Once the kerbs are laid, they’re backfilled with concrete or soil to provide support. Finally, the surface is cleaned, and our quality assurance team inspects the installation.
