Asbestos is a broad term for a group of naturally ocurring minerals with a crystalline structure and fibrous character giving them properties of high tensile strength, resistance to high tempreature and abrasion, high chemical resistance, and qualities of adhesion and cohesion. It's use has been widespread due to relatively low mining, processing and maufacturing costs.

The major period of use of asbestos in the building industry was between 1950 and 1976, and it's been used in more than 3000 different products. Bonded asbestos can be found in these associated roofing products:

• AC shingles, tiles and corrugated roof sheeting
• AC rainwater goods, gutters, downpipes and flashings
• roof area waterproof sheeting materials

The importation, manufacture and use of chrysotile asbestos has been banned since December 2003 and there have been strict guidelines set out by the OHS Regulation 2001 which govern the safe handling and removal of material containing asbestos.

It's our obligation as employers that our staff are trained in the safe handling of asbestos, and also as contractors that we hold relevant licenses for asbestos removal. The licensing system protects workers, builders, building occupants and the general public. Anyone who removes, repairs or disturbs areas of 200sqm or more of bonded asbestos must hold a bonded or friable asbestos licence, or a demolition licence.
