Asbestos is a naturally occurring mineral that was commonly used in construction materials, such as insulation, flooring, and roofing, until the 1980s. It was popular due to its durability and resistance to heat, fire, and chemicals.

However, it is now known to be highly dangerous when disturbed, as it can release tiny fibers into the air that can cause serious lung conditions, such as asbestosis, lung cancer, and mesothelioma. Exposure to asbestos can also cause other health conditions, including respiratory issues, asthma, and even kidney disease.

That's why it is essential to have a comprehensive asbestos survey carried out before any renovation or building work takes place to identify any potential hazards.
