The demolition contractor often deals with the concrete for demolition purposes. It involves tasks related to the renovation or replacement of the concrete. This repair work ensures the longevity and strength of the structure. The building material, concrete has several impressive features, one of which is robustness. That is why it takes time to complete the demolition project due to the hardness that concrete provides for the structure.
It is difficult to perform the job when there is a short deadline and also a compact space. To remove such obstacles, here are some of the best methods of concrete demolition that the contractors use.
A Traditional Method Of Using Explosives
It is no more a practical solution to the demolition jobs. This method is used majorly when the contractors need to break the larger pieces of concrete. Here the parts of the structures are fixed with explosives and destroyed. But it is not the best way to demolish the concrete structures. The reason is the explosives also damages the surrounding structures. Also, the modern structures come with lots of restrictions.
Remote Controlled-Brokk Demolition
The most efficient way to perform the demolition task is Brokk Demolition. This type of demolition is beneficial in various types of tasks, particularly those in remote areas. It is implemented with the help of the robots that are controlled with the help of the remote. The robots make the task efficient. It does not require many workers. This process provides lots of safety to the labours working on the site.
If you want to take the benefits of Brokk demolition, you can get the help of the certified companies and professionals that provide the advanced services of demolition like CA drillers at the affordable price. Their online presence will help you to figure out the best of what these companies offer.
Micro-Blasting
According to the experts, it is quite easy to break the concrete from the inside as compared to destroying it from the outside. The traditional methods of demolition take the advantage of this internal weakness of the structure and use explosives to break them. But, such a method also destroys the nearby construction.
This process covers the disadvantages of the traditional method. First, the drilling tool makes holes in the concrete structure. Now, the powdered cartridges are placed in these holes. It will help in breaking the concrete without producing much debris. Also, the structures in the surroundings are not harmed. This process does not produce much waste.
Hydraulic Bursting
This demolition technique has many advantages to notice. It is a silent demolition which includes hydraulic power unit. Just like the micro-blasting, the contractor drill holes in the concrete. There are fashions in which the holes are made, either in the straight line or in the diamond shape. The burster determines the various features of the holes like diameter, and spacing. After the holes are made, it is the perfect time to insert the burster head in them. It comes with lots of pistons and the pressure is applied on these pistons to break the concrete. It creates cracks in the concrete structure. This task is repeated and more cracks are formed in the entire structure. Now, this structure can be removed very easily.
Pressure Bursting
This type of demolition approves of dust and noise free demolition. Also, it is one of the safest methods of removing large slabs of concrete. There are two types of pressure bursting- chemical and mechanical bursting.
1. Chemical Bursting- In this type, expansive slurry gets into the boreholes to process the demolition.
2. Mechanical Bursting-Here, the motor produces hydraulic pressure, which runs the high-power splitting machine.
In both these techniques, the holes are drilled into the concrete so that lateral force can be applied to break them into pieces. Now it is time to clear the broken pieces with the help of the crane. The labours can also do it manually. But it will waste their time.
These are some techniques used in the demolition of the structures. These types of demolition will keep you aware of how demolition is executed by the professionals of the construction and demolition industry.
