Non-Explosive Demolition Method

Non-explosive demolition means the demolition work is done with some equipment without using any explosives. The different pieces of equipment used for the non-explosive demolition are:

 

Excavators and bulldozers. These are big machines used to demolish commercial buildings of small sizes. They are used for excavation of soil and transferring of debris to trucks.

 

Sledgehammer. It is a small handheld hammer used for the commercial demolition of a single column or small wall.

 

Wrecking balls. When the building is up to 6-7 stories, it cannot be demolished with the help of excavators or bulldozers, wrecking balls are used to perform the job. The wrecking ball crack is attached to a huge steel ball hanging from a steel rope.  The steel ball with force strikes the building; thus, demolishing that part of the building.

 

High reach excavators. These machines are used in the demolition of a tall building, particularly when demolition by an explosion is not possible. A building of up to 300ft in height can be demolished by this type of machine.

 

Explosive Demolition Method

Implosion is the process of commercial demolition with the use of explosives. The structure collapses if the supports of the building are removed. When the implosion technique is used, the main supports of the buildings such as the beams of a column and slab are fixed with explosives.

 

When these explosives are detonated, the column collapse and so is the structure itself. There are two types of implosion, depending on how the structure falls:

 

Falling like a tree. When there is free space is available near the building, this type of demolition is recommended. With this, steel cables are tied to the building to control the direction of the building when it falls.

 

Falling into its own footprint. When there are no free spaces available around the building and the structure around the building has to be protected, this method is used. In this type of demolition, the workers set the explosives on the floor below the middle part of the building.
