ASBESTOS REMOVAL INFORMATION

Ausnorth Asbestos Pty Ltd provides a high quality and safe removal of asbestos.

What is asbestos: Asbestos is a naturally occurring mineral found in the ground. It contains fibres that have excellent durability, fire resistance and insulating properties.

There are two main types of Asbestos:

LDB/FRIABLE A CLASS:

Friable asbestos is material containing asbestos that when dry, is in a powder form or may be crushed or pulverised into a powder form by hand pressure. This material poses a higher risk of exposing people to the air born asbestos fibres.

It is legislative requirement that all friable asbestos be conducted under the supervision of an Independent Hygienist who will issue a Clearance certificate when the removal has been completed and no threat of contamination has been found.

Examples:

  • Backing of sheet vinyl or vinyl tiles, linoleum flooring, fire damaged materials, fire doors, pipe lagging, sprayed on vermiculite (ceiling texture) insulation materials, etc.

LDB: Low Density Board is a lightly compressed board containing asbestos fibres in a calcium silicate plaster. It is sometimes referred to as asbestos insulating board. LDB can contain up to 70% asbestos fibres by volume. Asbestos cement sheeting typically contains between 5 to 20% asbestos. It looks similar to plaster board and asbestos cement sheeting known as fibro.

Examples:

  • Is typically used for internal wall and ceiling panels and as acoustic insulation and when used in ceiling tiles is commonly perforated

BONDED B CLASS:

When asbestos fibres are bound into the matrix of another material such as asbestos cement products or resin binder, it is known as bonded asbestos. It cannot be crumbled, pulverised or reduced to powder by hand pressure.

Examples:

  • Sheeting such as flat, profiled or corrugated, used on walls, ceilings, roofing and fencing.

Asbestos as a product was not completely banned from used In Australia until 31st December 2003. Asbestos in domestic building products has not been used since the late 1980’s, but if you house was build or renovated before 1990 it is thought that it will likely contain asbestos in some form.
