What is a concrete barrier?

How much are concrete barriers?

Our concrete barriers are rectangular-shaped blocks of concrete with the ability to be interlocked beside each other, reinforcing their stability.  Their shape is wider at the bottom and slightly more narrow on the top.

Although the purpose of a concrete barrier is quite simple, its level of application is wide. Here is where concrete barriers be used.

  • On roads for traffic control.
  • For perimeter protection during events (crowd control), construction and more.
  • For temporary construction works.
  • To protect workers from hazards such as heavy machinery.
  • To ensure the safety of motorways and dual carriageways under work
  • For security barriers at open rail lines.
  • To support a large, temporary structure, such as scaffolding, a stage, or a marquee tent.
  • To block unwanted vehicles (e.g. blocking vehicles from getting into a secure location, such as an airport).
  • For docking next to waterways.
  • For creating parking bays.
  • For securing a vacant area.
  • For preventing fly-tipping.
  • To be used as a base for public seating, public artwork or a public garden feature.
  • For use in a public playground or skate park.

What are the dimensions of a concrete barrier?

The following dimensions of our concrete barriers are 900×2000 mm. This equates to 90×200 cm.

These dimensions display that concrete barriers aren’t tall structures, but more than tall and wide enough to barricade your site from vehicles, as well as let members of the public know that they should not be going beyond those barriers.


We encourage you to get in contact with us if you have any further questions regarding the dimensions of our barrier blocks.

Difference between interlocking concrete blocks and concrete barriers

The difference between interlocking concrete blocks and concrete barriers may not seem like a lot, considering the uses we highlighted earlier, although physically they are different.

Interlocking concrete blocks are taller than our concrete barriers, which happen to be longer than the blocks. The difference in shape also allows our interlocking concrete blocks to be stacked upon each other, whereas the shape of our concrete barriers can’t facilitate stacking.

Additionally, interlocking concrete blocks have a wider degree of use as opposed to barrier blocks, which can’t be used for anything beyond the uses of a fence.

Are there any downsides to concrete blocks and barriers?

Depending on your needs there may be a few downsides to each of these products, here are some things to consider:

Downsides to concrete blocks

  • They can’t be moved manually
  • They can topple if stacked too high

Downsides to concrete barriers

  • They can’t stack upon each other
  • They can be climbed over
  • Can become weaker if subjected to high-velocity impact on a regular basis

How long does concrete last?

Concrete is resilient by nature, it can last for a number of years and beyond without any serious degradation. The only exception to this is if the blocks or barriers are in an environment in which they regularly receive forceful impact.

Are interlocking concrete blocks better than concrete barriers?

It’s not a question of which is better, but rather, which is more suited to your needs. You could use interlocking concrete blocks as a safety perimeter for a site, but you may find you can cover more length with fewer concrete barriers.

Both options have a similar level of application, yet both thrive under specific usage. If you’re considering purchasing either of these concrete products, don’t hesitate to get in contact so we can advise you best in relation to the project you want to use our products for.

What is the cost of a concrete barrier?

What is the cost of a concrete barrier?

For those looking to purchase a concrete barrier for their site, the cost of the barrier will depend on a few factors including:

  • The perimeter it will be barricading
  • If you choose to use Interlocking concrete blocks or Jersey barriers
  • The number of blocks/barriers you require
  • The size of barrier you opt for

We encourage you to get in contact with us directly if you are considering using our products for your site. If you can outline the details of your project, we will be able to provide you with a quote as well as any guidance you may require if you need it.

Are concrete blocks and barriers made on-site?

No, our concrete products are prepared, moulded, dried and checked on our site before they are transported or collected. Making them on your building site would require more space than you can afford to give, this can present a health hazard on your site, which we wouldn’t want to create.
