What Are the Basics of Concrete Barriers

Concrete barriers are essential for the preservation and safety of construction sites as well as a number of other settings. But if you have never used a concrete barrier before, what can you expect? Do they require a specific usage?

In this blog, we will answer the question ‘What are the basics of concrete barriers?’

At PPC Concrete Products, we are here to provide solutions for your construction needs, from the person working on their part-time project to commercial clients, and everyone in between.

Monthly construction output had risen an estimated 1.6% value in June 2023, and we would like to think our accessible concrete products had a small part to play by giving our clients easy access to reliable and easy-to-use construction solutions.

How are concrete barriers made?

How are concrete barriers made?

Concrete barriers are developed in two ways. Although there may be alternative development methods being used, the two we will mention are the most commonly known.

1.   Precast Concrete Sections

This is the most used method for concrete barrier creation. The process begins with preparing a mould that is created with the required shape of the barrier. Usually, steel bars are positioned in certain areas of the mould in order to reinforce its strength.

After this, a concrete mix is prepared and poured within the mould. Different concrete mixes exist depending on the desired outcome. But for most barriers, a mix that would ensure durability and strength would be used.

Once poured, the mould is then vibrated for an amount of time, this ensures any trapped air bubbles are removed. After this, the concrete filled mould is then left to cure for a number of days. The length can vary depending on the size of the mould and the mix used. Curing takes place in specific environments that ensure the curing process is not disturbed.

After the cure has completed, the mould is removed from the concrete. Sometimes there may be surface level issues that need addressing, once sorted, the barrier is ready to transport.

2.   Slipform paving

Slipform paving is a method used for larger industrial-scale projects, it is used in instances where a continuous stretch of concrete barrier is required. It makes use of a specialist machine known as a slipform paver.

It functions by having wet concrete being fed into the machine via a conveyor belt. This concrete makes its way through a mould, which shapes it into the required barrier shape. The slipform paver runs along a track, and places each barrier as it makes its way along the track.

The curing process takes place once the barrier has been set. Although this method can create concrete barriers in an incredibly quick fashion, the curing process has the potential to suffer based on the environment it is placed in.

Regardless of the method used, the final product is a strong and durable concrete barrier ready for transportation and installation on site.

What are the basics of concrete barriers?

The basics of any quality concrete barrier are almost universal, as long as your concrete barrier is made by qualified experts, you can expect the following basic functions…

  • Weight: Due to being made from concrete, a concrete barrier will naturally be heavy, meaning it will have a greater level of stability. In addition to this, it makes it incredibly difficult to move without mechanical assistance, which is extremely helpful in deterring anyone trying to trespass with a vehicle.
  • Durable: Again, because it is made from concrete, a concrete barrier will have a higher level of durability in comparison to other barriers made from other materials. It has the capability to withstand impacts and still remain effective in most cases.
  • Resistances: Concrete is fire-proof, and is not affected by other weather occurrences. This makes it incredibly useful for any environment.
  • Long-lasting: Concrete barriers, when created properly, transported safely, and used correctly, has the potential to last decades. Making them a great option for anyone looking for the most permanent solution possible.

Depending on the concrete barrier provider you opt for, you may find that they have additional features. For example, with PPC Concrete Products, our blocks have an interlocking feature.

The interlocking feature of our concrete barrier allows our barriers to physically connect with each other without any additional materials. As a result, the concrete barrier gains a greater level of structural integrity.

In addition to this, an interlocked group of barriers makes it extremely difficult for anybody to move the barriers without doing it in the right order, with the right machinery.

Concrete barrier alternatives — Which is the best?

In terms of all around effectiveness, concrete barriers are undisputedly the best. However, they may not be appropriate for every setting. In certain occasions, you may only require a barrier that can easily be transported, for a temporary event for example.

In this instance, metal barriers and plastic barriers are a helpful alternative, depending on the requirement. A plastic barrier may be helpful for traffic or pedestrian diversion on roadworks, whilst a metal barrier may be more appropriate for crowd control at a music event.

Is a concrete barrier indestructible?

No. Concrete barriers are not entirely indestructible, but their level of durability and resistance is far greater than a vast majority of its alternatives. The only issues that can cause significant damage instantly to a concrete barrier are…

  • Repeated high velocity impacts (Car crashes etc).
  • Explosions in its immediate vicinity.
  • Consistent forceful impacts with durable objects, which can cause cracks and chips over a sustained period.
  • Freak weather occurrences such as an earthquake.

How much is a concrete barrier?

The cost of a concrete barrier will vary depending on the provider you opt for as a result of their rates. Additional information may also contribute to the cost of your quote. Important information that can affect the price of a concrete barrier can include…

The last three points are subject to if they are rented from the provider, whereas the size of the barrier is subject to the provider creating more than one size of concrete barrier.
