Demolition contractors are called in when unsafe buildings need to be destroyed, usually to make way for new construction. They use proven methods to demolish these homes and buildings, such as wrecking balls to break apart concrete buildings and dynamite to get through dense areas. A high amount of strategy is involved, especially with the use of explosives. Safety is of the utmost importance in this industry, so be sure that the consultants or contractors you hire have the proper skills, licenses, and experience. Demolition contractors can also dismantle items, provide cleanup and abatement, excavation, and implosion. They may focus on commercial, residential, or industrial demolition, or all three. They may haul off scrap metal, and also provide concrete and asphalt crushing, cleanups, and recycling in keeping with the environment. Demolition contractors are frequently used in extensive renovations, remodeling, and addition projects, along with excavation and building projects. They should have experience in the construction industry, and know how to operate machinery such as backhoes, tractors, and cranes. Finding a reputable demolition contractor can be challenging, but knowing the right definitions can help in your search.
Excavation – To dig a hole in the ground to extract something, such as in an archeological site. Usually backhoes are used for this purpose, as are diggers.
Concrete crushing – To grind, break, crush or pound concrete into tiny bits using special machinery.
Abatement – To reduce, remove, or lessen something, such as in the case of mold or lead abatement as part of a building or remodeling project.
Demolition contractors commonly handle situations when a building has to be torn down. They also handle partial demolitions, such as of a wing or taking out a single wall in a home.
In many cases, partial demolition takes place as part of renovation of a building. Internal remodeling of a house may require the removal of walls or replacement of windows. Additions to a home often require the demolition of part of an exterior wall, breaking through to create a door.
At the other extreme, demolition can mean the total destruction of a large building. Although explosive demolition is actually a very small part of what contractors do, it is a very visible part of their image. Videos of the violent implosions of large structures circulate routinely.
In most cases, a building is dismantled carefully. Scrap metal and other materials are recovered as much as possible. Recycling has long been part of the history of demolition work, even before current environmental concerns. In some cases, especially when demolishing commercial or industrial buildings, care has to be taken to deal with toxic materials such as asbestos, referred to as 'abatement'. Although the classic wrecking ball is commonly used, for example to break down concrete, demolition tools also include tractors and backhoes. Cranes may be employed when dealing with taller buildings.
Many materials can be recycled. Concrete and asphalt, for example, can be crushed and turned into aggregate, which is used for roads and driveways. The site of a demolished building may require extensive excavation to remove foundations before new construction can begin. In some cases, demolition contractors may also offer excavation as a separate service. In many cases, their work is part of an overall construction or remodeling project, and they may be consulted on various phases. Demolition companies also handle cleanup of the site.
