Asbestos in Older South African Buildings: Why It Is Still a Silent Risk
Asbestos may no longer be used the way it once was, but it has not disappeared. Many older buildings in South Africa may still contain asbestos materials, especially properties built before asbestos restrictions became widely enforced.
This makes asbestos a silent risk. It may be hidden in roofing, ceilings, insulation, wall panels, pipes, floor materials, or other parts of a building. In many cases, property owners do not even know it is there until renovations, maintenance, damage, or demolition work begins.
At ENSA, we help businesses and property owners manage asbestos safely through professional asbestos removal and environmental services.
What is asbestos?
Asbestos is a naturally occurring mineral that was once widely used in construction and industrial applications because of its strength, durability, and heat-resistant properties.
For many years, asbestos was used in building materials because it was affordable and effective. However, it is now known to be hazardous to human health when asbestos fibres are released into the air and inhaled.
The danger is not always visible. Asbestos-containing materials can look ordinary, which is why professional assessment and removal are so important.
Why asbestos is still found in older buildings
Although asbestos is no longer considered safe, many older buildings still contain asbestos materials that were installed decades ago.
These materials may still be found in:
- Roof sheets
- Ceiling boards
- Insulation
- Gutters and downpipes
- Wall cladding
- Pipes and pipe lagging
- Floor tiles
- Industrial equipment
- Warehouses and factories
- Older residential properties
- Schools, offices, and commercial buildings
If these materials are in good condition and left undisturbed, they may not always pose an immediate risk. However, when they are damaged, broken, drilled, cut, removed, or disturbed, asbestos fibres can become airborne.
This is when asbestos becomes especially dangerous.
Why asbestos is called a silent risk
Asbestos is often called a silent risk because you cannot always see, smell, or feel it. The fibres are extremely small, and once released into the air, they can be inhaled without a person realising it.
Another reason asbestos is considered silent is that health effects may only appear many years after exposure. This means a person may be exposed during renovation, construction, or maintenance work and only experience health consequences much later.
Because of this delayed risk, asbestos should never be ignored or handled casually.
When does asbestos become dangerous?
Asbestos becomes dangerous when asbestos-containing materials are disturbed and fibres are released into the air.
This can happen during:
- Renovations
- Demolition work
- Roof repairs
- Ceiling replacements
- Drilling or cutting
- Storm damage
- Fire damage
- General wear and tear
- Poor removal practices
- DIY construction work
Even small jobs can create risk if asbestos is present. For example, drilling into an asbestos-containing wall or breaking an old asbestos roof sheet can release fibres into the air.
That is why it is important to identify asbestos before work begins.
Why DIY asbestos removal is risky
Some property owners may be tempted to remove asbestos themselves to save money. However, this can be dangerous.
Without the correct knowledge, protective equipment, removal methods, and disposal procedures, asbestos fibres can spread throughout the property. This can put workers, families, tenants, customers, and surrounding communities at risk.
DIY removal may also lead to incorrect disposal, which can create further environmental and health concerns.
Professional asbestos removal ensures that the material is handled, removed, transported, and disposed of safely.
Who is most at risk?
Anyone can be exposed to asbestos if fibres are released into the air, but certain groups may face a higher risk due to the nature of their work or environment.
This may include:
- Construction workers
- Maintenance teams
- Roof repair contractors
- Demolition workers
- Factory workers
- Property managers
- Homeowners renovating older properties
- Employees working in older buildings
- Waste handlers
Businesses and property owners have a responsibility to take asbestos risks seriously, especially when planning renovations, repairs, or demolition projects.
Signs your building may need an asbestos assessment
It is not always possible to identify asbestos just by looking at a material. However, there are some situations where an asbestos assessment may be necessary.
You should consider professional asbestos support if:
- Your building is old and has not been assessed before
- You are planning renovations or demolition
- Roofing sheets or ceilings are damaged
- You suspect asbestos-containing materials are present
- You are buying, selling, or managing an older property
- Contractors will be cutting, drilling, or removing old materials
- Storm, fire, or structural damage has affected the building
Getting professional guidance before starting work can prevent serious health and safety risks.
Safe asbestos removal and disposal
Asbestos removal should always be done carefully and professionally. The process may include identifying the asbestos-containing material, preparing the site, using protective equipment, removing the material safely, preventing fibre release, packaging the waste correctly, and ensuring it is disposed of at the correct facility.
The goal is to protect everyone involved and prevent asbestos fibres from contaminating the property or surrounding environment.
How ENSA can help
ENSA provides professional asbestos removal services to help businesses, property owners, and facilities manage asbestos risks safely.
Our team understands the importance of safe handling, correct procedures, and responsible disposal. Whether asbestos is found in a commercial building, industrial site, warehouse, or older property, ENSA can assist with professional support from start to finish.
Final thoughts
Asbestos may be hidden, but the risk is real. Older South African buildings can still contain asbestos materials, and disturbing them without proper precautions can be dangerous.
Before renovating, repairing, or demolishing an older building, it is important to consider whether asbestos may be present.
Professional asbestos removal helps protect people, businesses, and the environment.
