Types of Asbestos in NSW: What You Need to Know
Asbestos was used extensively in Australian construction for decades, and many homes and buildings across New South Wales still contain it today.
Known to cause severe health issues, asbestos use in construction was banned in Australia at the end of the last century.
Knowing what types of asbestos exist, where they were used, and why professional asbestos testing NSW is essential can protect your health and keep your property safe and compliant.
What Is Asbestos and Why Was It Used?
Asbestos is resistant to corrosion, heat and fire. It was also affordable, and so it was incorporated into thousands of building and construction products throughout the 20th century, making it one of the most widely used materials in Australian residential and commercial construction.
By the mid-1960s, asbestos-containing materials featured in almost 20% of all Australian housing stock.
What Are the Three Types of Asbestos Found in Australian Construction?
Three types of asbestos were used in Australian buildings and manufacturing, each with distinct properties and risk levels.
What is Chrysotile (White Asbestos)?
Chrysotile, or white asbestos, was the most commonly used type in Australia and is found in the majority of asbestos-containing building products. It has a curly fibre structure and was widely used in fibre cement sheeting, roofing products, and insulation materials.
What is Amosite (Brown Asbestos)?
Amosite, or brown asbestos, was used primarily for thermal insulation and fire protection in commercial and industrial buildings. Its straight, brittle fibres make it particularly hazardous if disturbed, as fibres become airborne easily.
What is Crocidolite (Blue Asbestos)?
Blue asbestos is the most dangerous of all asbestos types. It was used in spray-on insulation, pipe insulation, and some cement products, and was mined in large quantities in Western Australia.
What Is the Difference Between Bonded and Friable Asbestos?
Asbestos-containing materials are classified into two broad categories based on how the asbestos fibres are bound within the material. Understanding this difference is important for assessing risk and determining how the material should be handled or removed.
What Is Bonded (Non-Friable) Asbestos?
Non-friable, or bonded, asbestos is the most common type found in NSW homes. The asbestos fibres are bound within a solid material, such as cement, and are less likely to release fibres unless the material is damaged.
Common bonded asbestos products include:
- Corrugated roofing, such as “Super Six” roofing sheets
- Exterior fibro (fibre cement) wall cladding
- Internal fibro wall and ceiling linings
- Asbestos cement fencing
- Guttering, water pipes, and flues
- Moulded garden pots
What Is Friable Asbestos?
Friable asbestos is softer and more crumbly, meaning fibres can be released into the air far more easily. It is less common in residential properties but is found in certain locations and is treated as the higher-risk category.
Common friable asbestos materials include:
- Pipe and roof insulation
- Backing beneath vinyl and linoleum floor coverings
- Vermiculite or “popcorn” ceiling coatings
- Heat-resistant fabrics
- Bonded asbestos that has been damaged by fire or impact
Where Was Asbestos Used in NSW Homes and Buildings?
Asbestos was used in a wide range of locations, both inside and outside NSW properties. New South Wales had one of the highest concentrations of asbestos-containing homes in Australia, largely driven by the postwar housing boom and the widespread use of fibro construction.
Where Is Asbestos Found Inside a Home?
Common interior locations in older NSW homes include:
- Wall sheeting and ceiling linings, particularly in kitchens, bathrooms, and laundries
- Behind wall tiles and bathroom splashbacks
- Textured paint and patching compounds
- Floor tiles and the backing beneath vinyl sheet flooring
- Insulation around hot water systems, heaters, and associated pipe lagging
Where Is Asbestos Found Outside a Home?
On the exterior of older properties, asbestos may be present in:
- Corrugated or flat roofing sheets
- Eaves and soffits
- External wall cladding (fibro)
- Fencing
- Guttering, downpipes, and water pipes
- Outbuildings, sheds, and carports
Was Asbestos Used in Commercial and Industrial Buildings?
Yes. In commercial and industrial settings, asbestos was used more extensively for fire protection and insulation. Uses included spray-on fireproofing, acoustic insulation in walls and ceilings, pipe lagging in mechanical services, and gaskets in plant and machinery. Construction companies, property managers, and demolition contractors working on pre-1990 commercial buildings should treat all suspected materials as potentially containing asbestos until testing confirms otherwise.
What Is Fibre Cement (Fibro) and Does It Contain Asbestos?
Fibre cement, commonly known as fibro, is a composite building material made from cement reinforced with fibrous material. For most of the 20th century, asbestos was the fibre used to reinforce these sheets, making fibro one of the most common asbestos-containing materials found in NSW homes today.
Is Modern Fibre Cement Safe?
Modern fibre cement products do not contain asbestos and are safe for use in construction. They are normally made from cellulose fibre, cement, water, and sand. However, modern fibro looks very similar to older asbestos-containing sheeting, so any fibre cement in a property built or renovated before 1990 should be tested before any work begins.
When Was Asbestos Banned in Australia?
Australia implemented a staged ban on asbestos products over several years.
Key dates in Australia’s asbestos ban:
- Mid-1980s: Australia banned blue asbestos (crocidolite) and brown asbestos (amosite)
- Late 1980s: Asbestos was no longer used in fibre cement and most building products
- 31 December 2003: Australia finally banned the manufacture, import and use of asbestos.
Despite the ban, asbestos remains present in millions of Australian homes and buildings constructed or renovated before 1990. Many houses in NSW built or renovated between 1945 and 1990 contain asbestos.
Can You Identify Asbestos by Looking at It?
No. You cannot identify asbestos by sight, colour, or texture alone. Asbestos-containing materials come in a wide range of forms and appearances, and many have been painted over or incorporated into composite products that show no visible signs of containing asbestos fibres.
The only reliable way to be certain whether a material contains asbestos is to have a licenced professional carry out an inspection and collect samples for testing at a NATA-accredited laboratory.
Why Does Safe Asbestos Testing in NSW Matter?
Safe asbestos testing NSW is the essential first step for any building that may contain asbestos-containing materials. It protects the health of occupants, workers, and your local community, and it is a legal requirement in NSW before any demolition or significant renovation work can proceed on older buildings.
Who Needs Asbestos Testing in NSW?
The following groups are most likely to need NSW asbestos testing:
- Homeowners planning renovations on pre-1990 properties
- Property managers maintaining older commercial or residential buildings
- Business owners in premises built before the late 1980s
- Construction companies and builders working on sites with unknown building materials
- Demolition contractors preparing for structural works
What Does the Asbestos Testing Process Involve?
- A licensed asbestos assessor inspects the property and identifies suspect materials
- Small samples are collected from the suspect materials using safe procedures
- Samples are sent to a NATA-accredited laboratory for analysis
- A certificate of analysis is issued, identifying the presence, type, and concentration of asbestos fibres
- Based on the results, a management or removal plan is developed
Frequently Asked Questions About Asbestos Testing NSW
What types of asbestos are found in NSW homes?
The three types found in NSW homes are chrysotile (white), amosite (brown), and crocidolite (blue). White asbestos is the most common. All three are hazardous if fibres are disturbed and inhaled.
Is asbestos testing in NSW required by law?
NSW WHS Regulations require that asbestos be identified before demolition or refurbishment work on buildings that may contain asbestos. A licensed asbestos assessor must be engaged where required.
Can I test for asbestos myself?
It is really not recommended. Collecting samples without proper safety equipment and training poses a serious health risk. A licensed professional should always be engaged for asbestos testing in NSW.
What does asbestos testing cost in NSW?
Costs vary depending on the number of samples, the size of the property, and the laboratory used. Contact a licensed asbestos assessor for a site-specific quote.
How do I know if my home was built with fibro?
If your home was built or renovated before 1990, it may contain fibro (asbestos cement sheeting). The only reliable way to confirm this is through professional asbestos testing NSW.
