Encapsulating Asbestos: A Safer Alternative to Removal
Removing asbestos-containing materials is disruptive, costly and high-risk. Where the material is in good condition and unlikely to be disturbed, encapsulation — sealing it safely in place — is often the more practical and compliant choice.
Encapsulation vs removal
The risk from asbestos comes from loose fibres being released. Where an asbestos-containing material is stable, undamaged and not friable, encapsulation locks the fibres in and removes that risk without the disruption, cost and exposure of stripping it out. Removal is normally reserved for material that is damaged, friable or about to be disturbed by other works.
What the regulations say
Under the Control of Asbestos Regulations 2012, encapsulating or sealing-in asbestos that is in good condition — with no drilling, cutting or breaking — is generally classed as non-licensed work, though operatives still need the right asbestos awareness training and competence. Always start from a current asbestos survey and risk assessment, and use suitably trained (and where required, licensed) contractors.
The solution: a spray-applied encapsulation coating
Soteria is an elastic, crack-bridging coating that encapsulates asbestos-containing materials — such as cement roofing, cladding and panels — locking fibres in place behind a tough, decorative finish. It is UV-resistant and weatherproof, so it can be left fully exposed inside or out, and stays flexible as the substrate moves.
How it is applied
- Confirm the material is suitable for encapsulation from the asbestos survey
- Prepare the surface following safe-working controls
- Spray-apply Soteria to the specified coverage
- It cures to an elastic, weatherproof, decorative seal
Benefits
- Encapsulates fibres to prevent release
- Elastic and crack-bridging
- UV-resistant; suitable inside and out
- Far less disruption than removal
Frequently asked questions
Is encapsulation always allowed? No — only where the material is sound and won’t be disturbed. Damaged or friable asbestos usually needs licensed removal.
Do I need a licensed contractor? It depends on the material and method; always follow your survey, risk assessment and current HSE guidance.
