Asbestos Encapsulation
Safe, HSE-compliant encapsulation of asbestos cladding using spray-applied protective coatings. Avoid costly removal and disposal.
What Is Asbestos Encapsulation?
Asbestos encapsulation involves applying a protective coating system over existing asbestos-containing cladding, sealing the material and preventing fibre release. This approach is recognised by the Health and Safety Executive (HSE) as a safe, cost-effective alternative to removal where the asbestos is in good condition.
SprayGrade is particularly suited to asbestos encapsulation projects due to its spray-applied method, which creates a continuous, seamless membrane over the existing cladding without disturbing the underlying material.
Benefits of Encapsulation Over Removal
No Fibre Release
Avoids dangerous disturbance of asbestos fibres
Cost Savings
Up to 70% cheaper than full removal and disposal
No Disposal Costs
Eliminates hazardous waste disposal requirements
Faster Completion
Projects completed in days, not weeks
Building Remains Operational
No need to vacate or isolate areas
HSE Compliant
Recognised safe method under CAR 2012
When Is Encapsulation Appropriate?
Asbestos Is In Good Condition
Where asbestos-containing materials are intact, undamaged and not releasing fibres, encapsulation provides long-term protection without the risks of removal.
Cladding Is Structurally Sound
The underlying cladding must be structurally adequate. Severely corroded or damaged sheets may require局部 replacement before encapsulation.
Long-Term Management Plan
Encapsulation is part of a long-term asbestos management plan. The material remains in place and must be monitored, but the coating significantly reduces risk.
When Removal May Be Required
- • Asbestos is severely damaged or degraded
- • Cladding has lost structural integrity
- • Major refurbishment or demolition is planned
- • Building use is changing and higher risk profile
- • Asbestos is in a high-risk location (e.g., easily accessible, vulnerable to impact)
Why SprayGrade for Asbestos Encapsulation?
SprayGrade's spray-applied method makes it ideal for asbestos encapsulation. The system creates a continuous, seamless protective layer without disturbing the underlying material.

Complete encapsulation with no gaps or weak points
Weatherproof
Immediate waterproofing and weather protection
UV Resistant
Protects underlying asbestos from UV degradation
Long Service Life
Up to 10+ years before recoating required
Colour Options
Available in multiple RAL colours for aesthetic improvement

Is asbestos encapsulation legal and HSE compliant?
Yes. The HSE recognises encapsulation as a safe, compliant method under the Control of Asbestos Regulations 2012 (CAR 2012) where the asbestos is in good condition. Encapsulation must be recorded in the asbestos management plan and the material monitored.
How long does asbestos encapsulation last?
Properly applied SprayGrade encapsulation typically lasts 10+ years before recoating is required. The coating protects the underlying asbestos from weathering and UV degradation, extending its safe service life.
Can encapsulated asbestos be overcoated later?
Yes. SprayGrade can be overcoated when the time comes for maintenance. This is far simpler and cheaper than removal, and maintains the encapsulation integrity.
Do I need to inform anyone before encapsulating asbestos?
Yes. The work should be notified to relevant parties and recorded in the building's asbestos management plan. A licensed asbestos contractor should survey and assess the material before encapsulation begins.
What's the cost difference between encapsulation and removal?
Encapsulation typically costs 50-70% less than full removal and disposal. Savings come from avoiding: licensed removal contractors, hazardous waste disposal, scaffolding for extended periods, and building downtime.
