Understanding Asbestos in Building Materials
Asbestos in Everyday Building Products
Asbestos, particularly Chrysotile, has been incorporated into a range of building materials, including toilet systems, banisters, and window ledges. This integration typically occurs under the PVC plastics and resins category.
Examples of Asbestos-Containing Products
- Pub Toilets: Despite their color, cisterns can contain asbestos.
- Toilet Seats: Chosen for their water resistance and durability.
- Water Tanks: Noted for longevity and water resistance.
- Window Ledges: Prone to water leakage, making them common sites for asbestos use.
Asbestos Flooring
Old-fashioned or speckled floor tiles are likely to contain asbestos. Types include thermoplastic tiles (20% Chrysotile), PVC tiles (70% Chrysotile), and paper-backed flooring (100% Compressed Chrysotile).
Risks and Removal
While not high-risk, the main concern arises during removal due to asbestos in adhesives.
Asbestos Bitumen Products
These products, such as roofing felt and damp proofing, generally contain about 8% white asbestos, used for water resistance and fireproofing.
Examples and Usage
- Sink pads: Used for soundproofing.
- Galbestos: Profiled sheets with external asbestos lining.
Texture Coatings and Asbestos Cement
Texture coatings like Artex, often used on ceilings and walls, may contain about 5% asbestos. Asbestos cement, used in various forms, typically contains 10-15% asbestos.
Common Applications
- Corrugated Sheets: Used in farmhouses and sheds.
- Slates and Tiles: Appearance similar to modern tiles, requiring careful age assessment.
- Flues, Valves, and Vents: Contain asbestos for heat resistance.
Asbestos in Entrance Ways
Low-rise block flats' entrance ways may contain asbestos cement for fire resistance, posing a risk if damaged.
