Asbestos refers to a set of six naturally occurring fibrous minerals. Asbestos has six primary subclassifications; chrysotile, crocidolite, amosite, anthophyllite, tremolite, and actinolite. Among these, chrysotile and amosite asbestos are the most common.
1 in 3 houses in NZ contain Asbestos which makes it a nationwide issue, especially with houses built in the 80’s and 90’s.
If your house or building was built or renovated in the 80’s or 90’s, it is likely to contain Asbestos in some form. To confirm whether a material contains asbestos is to have it tested by a qualified laboratory. We only recommend testing suspect materials if they are damaged (fraying, crumbling) or if you are planning a renovation that would disturb the suspect material.
As a general rule, if a building was constructed:
- Before mid-1980s it is very likely to have materials containing asbestos
- Between mid-1980s and 1990 it is likely to have materials containing asbestos
- After 1990 it is unlikely to have material containing asbestos
According to the Auckland City Council, homeowner’s are often unaware of the existence of asbestos and the serious health risks its removal brings. Materials containing asbestos are often brittle and break easily; if disturbed fibres are released into the atmosphere and can be breathed in up to 30 days after its removal.
Asbestos can be found in many building materials:
