How Does Building Implosion Works?

There are various methods applied when it comes to demolishing a building. One of these methods is implosion. Unlike the traditional method like crane and wrecking ball, implosion can demolish a 20-story skyscraper. This is the preferred method especially for demolishing large structures. It’s not rocket science, but it surely is challenging. If you want to know more about implosion, contact demolition company Chicago. But for regular readers like you, continue reading this article for the basic information about implosion.

The Process of Implosion 

We would like to explain this as simple as possible. So here we go. The method will become a success if you remove the support structure of the building. The support section should fall off below its point. Once the heavy part of that structure explodes, it will fall off to the lower part and then cause a damage to the building. In this method, it’s the gravity that will do the work and the explosives are the trigger factor.  

The demolition crew will put the explosives on different areas of the building. The most important key is to plan where to place the explosives and then execute the plan correctly. The damage done by the explosives will be enough to collapse the building. After the implosion, the crew will then cleanup the pile of rubble.  

Examining the Architectural Blueprints  

The first step of building implosion is examining the blueprint of the building. This way, the professionals will know where the structural support of the building is. The blaster crew will then tour the area to take notes about the support structure of each floor. Once the data are gathered, the plan of execution is then made. They will make decisions like what kind of explosives to use, where to put them and how to time them. The challenge is then what direction would the building fall? Ideally, it should fall on a safe and vacant area. The building could be topped over to the north or straight down into its own.  

Dynamites and Detonators 

You now have an idea about the basic thing about building implosion. Now, how do blaster crews decide what kind of explosives to use for the building? If the building has concrete columns, blaster crews will use the traditional dynamite. Dynamite is a mixture of chemicals and once ignited, it burns quickly. A large volume of gas is produced, which then expands and applies outward pressure on the columns. This will then shatter the concrete into chunk, then the building will collapse.  

If the columns are made of steel, a specialized explosive is going to be used. Blaster crews usually use RDX or an explosive made of clyclotrimethylenetrinitramine. The compounds of this explosive expand at a high rate speed of 27,000 feet per second. The high velocity slices through the steel column and splits it in half. Once it’s done, the blaster crews might add dynamites to push the column over a certain direction. Using dynamite and RDX will need a sever shock, which  is achieved by using a blasting cap.
