A Rundown on Bollards and What They Are Used For

I stand tall and strong, you see me every day and I keep everyone safe: What am I? A Bollard!

Yeah, don’t worry if you didn’t get it. To be completely honest, who even recognises bollards to begin with? You probably walk past one everyday or park next to one at your local supermarket and don’t even realise it.

They are used just about everywhere and anywhere and are very much a part of our day-to-day lives, but what exactly is a bollard used for? We know they stop us from parking in unauthorised areas, but surely that’s not all.

Let’s find out.


What is a bollard used for?

In a nutshell, a bollard helps establish a perimeter, both visual and protective, and is engineered to keep pedestrians and motorists safe from potential harm. But that’s not all. Bollards come in a wide variety of shapes and sizes, made from metal, plastic, stone and/or cement.

Furthermore, some types of bollards have been designed to absorb a considerable amount of impact typically caused by errant vehicles, preventing secondary collisions, and keeping pedestrians and motorists safe from injury.

This leads us to our next question, where should bollards be placed? Well, there’s no better way to explain where bollards should be placed than actually finding out the different types of bollards available.


What are the different types of bollards

1.   Removable & retractable bollards

Removable bollards are an easy to use solution for controlling access to certain areas including private property or public spaces that are often prone to authorised parking. Similarly, automatic retractable bollards offer access control to pedestrian areas for emergency and authorised vehicles, prevention of unauthorised parking, and site entrances.

Applications for removable/retractable bollards

  • Prevent unauthorised access/parking
  • Access control to pedestrian areas for authorised vehicles
  • Control access to site entrances


Industries that use removable/retractable bollards

  • Council and government buildings
  • Road and public safety
  • Construction sites
  • Car parks
  • Sports and recreation


2.   Construction bollards

As the name suggests, these types of bollards are typically found on construction sites and/or road construction projects. The main purpose of a construction bollard is to protect a designated area and the workers in it from any external accidents by redirecting traffic or preventing it from entering. Made from a flexible and brightly coloured plastic with a reflective tape wrapped around, the bollard acts as a visual deterrent.


Applications for construction bollards

  • Prevent external accidents
  • Prevent traffic from entering
  • Visual deterrent


Industries that use construction bollards

  • Construction sites
  • Road and civil safety


3.   Security & Car park bollards

Serving a similar purpose to the construction bollard, security bollards have been designed to protect assets, such as ticket machines, and pedestrians from low-speed collisions. The only difference lies in the construction of the bollard. Rather than plastic, security and car park bollards are almost entirely made out of steel, are filled with concrete and generally decorated. Depending on the location, impact resistance of the bollard is based on how it is fixated to the ground.


Applications for security & car park bollards

  • Protect car park assets, like ticket machines, and pedestrians
  • Protect assets, students, and visitors at educational institutions
  • Protect assets, patients staff and visitors at hospital car parks


Industries that use security & car park bollards

  • Council and government buildings
  • Public safety
  • Car parks
  • Hospitals
  • Sports and recreation
  • Shopping centres
  • Schools and universities
  • Outside restaurants


4.   Marine bollards

Marine bollard

You might have guessed it, marine bollards are used to anchor boats and are a crucial part of mooring systems. Based on its intended use, mooring bollards come in a range of shapes and sizes with a mushroom shape appearance. This allows ropes to be dropped over the top and will not easily come loose. Additional cross rods provide additional security for tying ropes around the bollard.

Applications for marine bollards

  • Part of mooring system to secure boats

Industries that use marine bollards

  • Docks
  • Jetties


5.   Hostile vehicle mitigation bollards

Offering the highest level of protection for high-value assets and people, HVM bollards are highly recommended for sensitive and high-value locations. They provide the most protection against out of control vehicles and vehicle-based attacks, making them ideal for protecting locations with large masses of people like an outdoor market or religious congregations. They also provide the most effective form of security barriers for high-value assets such as embassies, government buildings and airports.


Applications for HVM

  • Provide high level protection in airports, government buildings, embassies
  • Provide high level protection for areas with large masses of people such as festivals, outdoor markets, religious meetings
  • Provide high level protection against out of control vehicles in high-traffic areas


Industries that use HVM

  • Council and government buildings
  • Events, public safety
  • Sports and recreation
  • Educational institutions


6.   Bicycle parking bollards

Bicycle parking bollards provide a hitching point for a secure bike lock-up and typically consist of post-and-arm shape for 2 bikes to be secured. The main purpose of bicycle parking bollards is essentially providing cyclists an area to safely park and lock their bikes.


7.   Guardrails/ end terminal bollards

Guardrails and end terminal bollards have been engineered to absorb impact and protect motorists and assets in the event of a collision. As a non-gating and non-redirective deterrent, guardrails help ‘capture’ errant vehicles and effectively minimise potential injuries, secondary accidents/collisions and other hazards. They are particularly useful in areas with limited space such as bridges, tight corners or roundabouts.


Applications for HVM

  • Provide protection in areas with limited space: bridges, roundabouts, highways, roads
  • Provide safer work zones by protecting employees
  • Stop errant vehicles and help keep pedestrians and motorists safe


Industries that use HVM

  • Council and government buildings
  • Events, public safety
  • Sports and recreation
  • Educational institutions
  • Mining
  • Factories & warehouses

Why is replacing your piping system so expensive?

Why Is Replacing Your Piping System so Expensive?

We take a look behind the scenes of what really goes on when replacing your piping system.

It’s come to your attention that replacing the piping system is actually really expensive. But why? You may not know this, but it’s going to take a lot more than just a plumber. In terms of outdoor piping, drainage is typically underneath concrete slab, while indoor renovations require a passage for drainage pipes to make way for wastewater.

Whether your pipes have reached the point of beyond repair and your hands have been forced, or you’ve decided it’s time to remodel the bathroom and thought heck, why not replace the pipes while you’re at it.

This is the untold story of when concrete cutting crosses paths with plumbing.


When you need drainage channels in concrete slab

If you noticed water pooling near a doorway, wall or outside in the yard with nowhere to go, you may have a drainage issue. Flooding indoors can lead to rising damp, stains and cause serious water damage, while proving to be an unsightly inconvenience when entertaining outdoors.

This is when you’d typically seek a concrete cutter to cut drainage channels in concrete slab. Whether it’s new or old concrete slab, a professional can easily create drainage channels for water to escape.

Depending on the size of the job, costs will vary:

  • For smaller jobs, hand-held saws provide a quick and easy solution.
  • For medium-sized jobs, a track-mounted saw may be necessary to cut a perfectly straight channel in one clean cut.
  • For longer channels, a road saw is the most effective and accurate at cutting longer channels.


When you need new passages and drainage holes through walls, floors or the roof

If you’re doing a complete overhaul of your bathroom or kitchen you will most likely need to cut new passages for pipes and drainage holes. Concrete core drilling is the easiest and most effective way to create holes through any structure to make way for pipes, be it through walls, floors or the roof.

Depending on the size of the job, core drills can create holes over a metre deep and a metre wide using special diamond core drill bits.


Best opportunities to replace your piping system

Replacing exposed piping

If you’re not looking to tear up the yard and knock down walls, consider replacing any pipes that are exposed. Although it may still be a big job, replacing exposed pipes is fairly upfront.


Replace during a renovation

At the very least, take this opportunity to inspect and if necessary, replace any piping that is exposed when you tear down walls and open up the floor. If you are installing new fixtures that require a water passage you’ll most likely require a concrete cutter for drainage channels and holes to prevent water from going where it shouldn’t be.


Tradies to hire

In most cases, you may only need to hire a professional concrete cutter and plumber when replacing your piping system. Bathroom or kitchen renovations may require additional trades including a licensed electrician, tiler, bathroom waterproof, carpenter and cabinet maker (if you’re going custom).


How much it’s going to cost to replace your piping system

You’re looking at around $6,000 to $12,000 to replumb an entire house, depending on the complexity of piping, material and features required.

To replace the entire drainage system you can expect to fork out around $5,000 to $20,000, again depending on the complexity of piping, material and features required.

Need a professional concrete cutter?

In reality, we wouldn’t recommend conducting DIY concrete cutting or plumbing for that matter (it’s illegal in WA), as the consequences severely outweigh the few dollars you save initially. When it comes to combining drainage channels, passages and core drilling holes, you can always rely on the professionals at Diamond Cut Concrete.
