Asbestos is a naturally occurring mineral that was widely used in construction materials until the 1980s. It was valued for its heat-resistant properties and was commonly found in insulation, roofing materials, and flooring.

However, asbestos is now recognized as a serious health hazard. When asbestos fibers are released into the air and inhaled, they can cause a variety of respiratory illnesses, including lung cancer, mesothelioma, and asbestosis.

Because asbestos was so widely used in construction, it is likely to be present in many older buildings. That's why it's important to have an asbestos survey conducted on your property if you are planning any refurbishment or demolition work.
