Corrugated cement sheets installed before the 1980s frequently contain asbestos (typically chrysotile). Identification steps:
- Age of building – Pre-1980s (UK: pre-1999) construction strongly suggests asbestos content.
- Product markings – Look for “asbestos,” “chrysotile,” or manufacturer codes on the sheet underside.
- Visual condition – Weathering, cracks, drilling holes, or breakage increase fiber release risk. Assume asbestos if damaged.
- Professional sampling – The only definitive method. A UKAS-accredited surveyor collects samples for PLM analysis.
If Asbestos Is Confirmed or Suspected
- Do not cut, saw, drill, sand, pressure-wash, or vacuum.
- For removal or encapsulation, engage an HSE-licensed asbestos removal contractor.
- Maintain an asbestos register and management plan per the Control of Asbestos Regulations 2012.
Undisturbed, intact asbestos cement poses minimal risk. The danger arises during disturbance or deterioration.
