Summary
Non-friable asbestos refers to asbestos-containing materials in which the fibres are firmly bound within a matrix (for example cement or resin), making them less likely to release airborne fibres under normal conditions. In land remediation, environmental consulting and development compliance, distinguishing non-friable from friable asbestos is critical for risk assessment, remediation strategy and regulatory compliance.
Definition
Non-friable asbestos is asbestos-containing material (ACM) in which the asbestos fibres are bonded or cemented and cannot be easily crumbled, pulverised or reduced to powder by hand pressure when dry.
Why It Matters
For environmental consultants, remediation specialists, developers and regulatory stakeholders in Australia, the term “non-friable asbestos” is highly significant because:
- It influences the risk profile of a site. Bonded/non-friable ACMs usually pose lower immediate fibre-release risk compared with friable ACMs, but they are not without hazard if disturbed, deteriorated or during demolition.
- It affects regulatory obligations and required licences. For example, under SafeWork NSW guidance, removal of over 10 m² of non-friable asbestos in NSW may require a licensed removalist.
- It drives the design of site investigation, remediation and validation workflows. Consultants such as Nova Group Pacific integrate non-friable asbestos assessment into contaminated land programs, soil and waste classification, and project compliance tracking.
- It affects the cost, timing and planning of redevelopment or land-use change projects. If bonded ACMs are present, the developer or site owner must factor in appropriate asbestos management or removal strategies to ensure project viability and avoid unexpected compliance issues.
When It's Required
Trigger conditions
You must consider non-friable asbestos when:
- Conducting a site assessment or due diligence on buildings constructed or altered prior to the bans on asbestos use (for example pre-1990s).
- Planning building refurbishment, demolition or major renovation works, especially with materials likely to contain asbestos cement sheets, vinyl asbestos tiles, roofing sheets, pipes, asbestos-cement pipes or cladding.
- Carrying out a contaminated land investigation or excavation where buried asbestos materials or legacy ACMs (non-friable) might be present in soil or fill.
- Developing or updating an asbestos management plan (AMP) or asbestos register for a facility, workplace or development site, which must treat non-friable ACMs differently to friable ones.
- Ensuring compliance with regulatory frameworks such as the Work Health and Safety Act 2011 (WHS Act) and associated codes of practice, for example the classification and removal of asbestos-containing materials.
Legislative context in Australia
In New South Wales, removal of non-friable asbestos over a threshold area requires a Class B licensed removalist; whereas any amount of friable asbestos requires a Class A licence.
The presence of non-friable asbestos in soil or land requires reporting and management under the Protection of the Environment Operations Act 1997 (POEO Act) where applicable.
