Demolition and dismantling a building mean destroying or removing any fully built building structures or any part of some high-floor buildings in a pre-planned and controlled manner. Some common things very important for demolition are design life and destroying an old building with some selected techniques.

Everything matters in the demolition of buildings. But all these two things are the major factors that affect the demolition of buildings. When demolition is done, the surrounding area of the damaged building is not affected.

Manual demolition

‘This type of demolition is also known as hand demolition. Also, this demolition method is specially used for breaking some small structures in populated areas. Laborers do this type of demolition with their hands.

As in densely populated areas, large machines cannot be able to go to the sites as these areas are very crowded. In this demolition, laborers use hammers, wire cutters, welding cutters, and many more tools.

Wrecking ball demolition method

In this demolition method, a steel ball with a weight of around 0.5 to 2.0 tons is hung from a crawler-mounted crane. These steel balls have a very high impact as they can break the concrete or machinery. In this method, two techniques are most commonly used.

• First is a vertical drop of a wrecking steel ball.
• The second is a swing action of wrecking a steel ball 

This method is used in industrial dismantling Houston, where the area is not crowded.

Pusher arm demolition method

This is a common method of demolition used for buildings. This machine has a hydraulic excavator, which is lifted with a steel pusher arm and pushed from outside the building. In this method, the machines should have a rigid base for operation from the ground. 

Suppose two buildings are connected, then the building to be demolished is separated from the other building with the help of hand demolition so that it would not cause any effect on the other building.
