Concrete removal in Melbourne is one of the most dreaded housework as it can be quite a tricky task.
It is difficult to determine the best way to remove it without damaging the surrounding area or leaving behind an unsightly mess. Hence, it is necessary to understand various methods of concrete removal and find the best one for your needs.
In this blog post, we will explore six methods for removing defective concrete so you can get the job done efficiently and effectively.
But firstly, we are dividing the job into two categories—small concrete removals and big projects like pavements and bridge decks.
1. Sledgehammering
One of the methods for concrete removal in Melbourne is by using a sledgehammer. It is specifically used for smaller concrete jobs.
For a slab of concrete that is less than 4 inches thick, you will use a sledgehammer. If the slab is four or more inches thick, you need a demolition hammer.
Start by wearing PPE yourself and then cover the concrete slab with plastic sheets. Now here’s how the process goes:
First, you should dig beneath the concrete if possible.
Start tearing up the concrete roughly a foot from its edge. Move towards the direction of the slab's centre.
As you break the concrete, you can pry the concrete up with a long bar or wrecking bar. You can also place a fulcrum under the bar, which will provide more leverage.
Mesh wire can be cut with bolt cutters. But a metal blade or cutoff wheel is necessary to remove the rebar.
Now you can move the rubble using a wheelbarrow to a flatbed truck or another vehicle equipped to tow the load.
Finally, ensure you are properly disposing of the concrete debris and in compliance with your local laws.
2. Jackhammering
Using a jackhammer is one of the most common methods for removing defective concrete.
This method involves using a heavy-duty tool equipped with a chisel bit to break up and dislodge the concrete slab. Jackhammers come in both handheld and rig-mounted varieties. They may be driven by hydraulics, pneumatic air compressors, or electricity.
Jackhammering is great for removing large slabs of defective concrete, but it can also be quite loud and messy, so make sure that you are wearing protective equipment and taking necessary safety precautions while using this method.
3. Hydro Demolition
The second type of method for concrete removal in Melbourne is hydro demolition, another popular method.
This technique utilises high-pressure water jets to break up and dislodge the slab without causing any damage to the surrounding area. It breaks down concrete into bits the size of sand and gravel with excellent efficiency. Also, it is helpful when you want to protect and clean the steel reinforcement for reusing later.
Though hydro demolition is effective at removing large amounts of concrete quickly, it does require specialised equipment, which may not be available in all areas.
Thus, when you are in discussions with your contractor, you must ensure that they have the right equipment to carry out hydro demolition.
4. Chemical Removal
Chemical removal is another option for defective concrete removal in Melbourne.
This method involves drilling holes in the concrete and pouring a chemical solution into them to weaken the slab’s surface before breaking it apart by hand or with other tools. It may take anywhere from a few hours to a day for the concrete to break apart.
Chemical removal is relatively simple and cost-effective; however, it should only be used as a last resort due to its potential environmental impacts if improperly handled or disposed of incorrectly.
5. Cold Chiseling
Cold chiselling is another option for smaller slabs of defective concrete removal in Melbourne without causing too much disruption to the surrounding area.
It involves using an electric chisel or hammer drill with an appropriately sized bit to break up and remove small patches of defective slabs from your property. Cold chiselling requires patience and precision but can produce great results if done correctly.
6. Hammer & Chisel
The hammer and chisel technique is one of the oldest methods for removing defective concrete from your property.
It is manually striking away at the slab with a heavy-duty hammer until it has been broken into pieces that can then be removed from your property easily by hand or with other tools such as a wheelbarrow or shovel.
Conclusion
Defective concrete can be difficult to remove without causing damage or disruption to your property, but these are the several methods available that allow you to do so safely and efficiently.
From Jackhammering to hydro demolition, all are viable options depending on the project you are undertaking and how much time you have to devote to it.
With some research and planning beforehand, you should have no trouble finding a safe yet effective way to remove faulty concrete from your home or business premises!
When discussing the project with your contractor, start with the type of project, as it will give an immediate idea of what he’s supposed to do. For example, you might need pool removal in Melbourne, and when you communicate it with the contractor, they will understand the requirements.
That’s all. We hope you have a better understanding of concrete removal in Melbourne after reading this blog.
Stay safe!
