Understanding Asbestos in Piping
Asbestos is a mineral once commonly used in construction for its heat and fire resistance properties, but whilst it was effective, its fibrous nature posed significant health risks when inhaled or ingested. In older buildings (typically before 1999), asbestos may be present in various piping systems, including:
Drain Pipes – Often made from asbestos cement, these pipes resist corrosion.
Gutters – Asbestos was used in guttering systems for added durability.
Ventilation Flues – Commonly found in industrial applications, these pipes utilised asbestos for heat resistance.
In this blog, we discuss on ways to identify asbestos piping and lagging, the dangers it presents, why you need to leave it alone and the importance of contacting an asbestos consultant as soon as possible.
Dangers of Asbestos Piping and Lagging
The primary risk occurs when asbestos pipes become damaged, releasing harmful fibres into the air, which can lead to severe health issues such as mesothelioma and lung cancer​.
Steps to Take if You Suspect Asbestos Piping
- If pipes are intact, do not disturb them
- Hire a qualified asbestos consultant to inspect and test the piping​
- If asbestos is confirmed, adhere to an asbestos management plan that may include encapsulation or removal​
Recent statistics indicate that asbestos continues to pose a significant risk in the UK, with over 5,000 deaths attributed to asbestos-related diseases each year. The Health and Safety Executive (HSE) reported that in 2022 alone, there were 2,257 deaths from mesothelioma, a cancer strongly associated with asbestos exposure. Additionally, new cases continue to emerge, demonstrating that the legacy of asbestos piping, lagging and insulation wraps in buildings remains a critical health concern.
When & Why Were Asbestos Pipes Used?
Asbestos cement pipes gained popularity in the early 1900s and mid-20th century due to their durability and corrosion resistance, making them a common choice for various applications, including industrial sewer pipes, chemical piping and other types of cement-based pipes.
However, many of these old pipes contained asbestos fibres, posing significant health risks. When these pipes deteriorate or fail, they can release ingested asbestos, particularly in situations where the pipes are buried underground. Consequently, pipe failures not only compromise infrastructure but also increase the likelihood of asbestos exposure, which can lead to serious health complications.
Identifying and managing these risks is crucial to ensure safety, avoid its exposure and prevent health issues associated with asbestos exposure. Effective asbestos management involves conducting thorough surveys and tests to determine the presence of asbestos in piping systems. Professional asbestos consultants can perform inspections and collect samples for laboratory analysis, allowing property owners to make informed decisions about remediation or maintenance.
Identifying Asbestos Cement Pipes in Your Home
Identifying asbestos cement pipes in your home or workplace can be challenging, as there are hundreds of different materials and products that may contain asbestos.
Historically, pipe manufacturers used asbestos as it was often deemed low risk and not harmful to human health, which is why you shouldn’t expect to find warning labels or hazard signs on all asbestos materials within a building, however there is of course more than sufficient evidence to show asbestos cement water pipes, especially those used for drinking water, can lead to an increased risk of stomach and gut cancers due to the asbestos fibres. Asbestos is also undetectable by its smell, making it even harder to identify without the input of a professional.
The range of asbestos-containing cement products is extensive, including roofing materials (such as sheeting, panels, and tiles), pipes (like foul drains, wastewater collection systems, flues, and guttering), flooring and even less common items like and insulating boards.
Identifying Whitish-Grey Coloured Pipes
Asbestos cement pipes typically appear white or light grey but may be painted or covered with various materials, such as black bitumen. While these pipes are becoming increasingly uncommon in residential properties, they can still be found in some homes.If you suspect your home or property contains similar pipes or have any concerns about asbestos, please reach out to us for unbiased advice.
Identifying Asbestos in Piping
Asbestos was commonly used in construction in the mid-20th century, with Chrysotile, or white asbestos, being the most prevalent type found in pipe work due to its beneficial properties. Other forms of asbestos, such as wraps, insulation, lagging or hard-set asbestos, may also be present in piping systems. Many of these materials pose significant health risks, making it crucial to understand the type of asbestos involved.
If you have any concerns about asbestos in your pipes or pipework, it’s essential to seek advice from a qualified expert. Getting an asbestos survey or asbestos testing done is a crucial step in identifying any potential risks.
Today, gutters, drain traps, and downpipes are made from safer materials such as metal and PVC plastic. However, asbestos was commonly used in these products before the year 2000, especially prevalent before 1980, so buildings after this date are usually okay for safe occupancy.

If you discover asbestos pipes on your property, it’s natural to feel concerned about potential dangers. While asbestos is indeed a hazardous material, several factors can influence the level of risk associated with your pipes and their impact on your health.
Condition
Asbestos cement pipes can be safe if they are in good condition and properly sealed. However, it’s wise to conduct an asbestos survey to assess potential risks. Damaged, broken, frayed, or eroding pipes can become hazardous and require immediate attention.
Location
The location of asbestos pipes plays a significant role in their risk level. Pipes in low-traffic areas generally present less danger than those in high-traffic zones. Underground pipes may be safe to leave undisturbed, but any visibly damaged asbestos cement pipes should be addressed promptly, and removal may be the best option. An asbestos survey by a qualified consultant is recommended.
Age
The age of asbestos pipes is also a critical factor. Over time, these pipes can become brittle and damaged. When broken, asbestos can release friable materials into the air, increasing the risk of airborne fibre exposure. Most asbestos cement pipes have a lifespan of around 50 years, so they can last a long time with proper maintenance.
The Impact of Asbestos on Water Supply Systems
Asbestos has been a concern in various infrastructures, including drinking water distribution systems. Historically, pipes that contained asbestos, particularly cement-based pipes, were used extensively, leading to significant health risks. Studies have indicated that exposure to seven million fibres from asbestos can occur in environments where these pipes are present.
This includes old pipes that may be buried underground and can eventually decompose over time, potentially contaminating water supplies and causing cancer. Many utility companies have been working to address these issues – regulations have been implemented to ensure public safety regarding asbestos exposure limits, especially for those working in proximity to materials containing asbestos. It is crucial for property owners to be aware of the potential presence of asbestos in their plumbing and to seek advice from professionals.
