Where appropriate, asbestos can be encapsulated, rather than being removed. A risk assessment should be carried out prior to any asbestos encapsulation works to ensure this is the best course of action.
Asbestos encapsulation can take many different forms, depending on the nature of the material. Encapsulation can be defined as the application of an impervious material, which is secured over or around an asbestos containing material (ACM), and is designed to prevent the release of fibres under foreseeable conditions, such as vibration, impact and age degradation. Encapsulation should maintain the beneficial properties of the original asbestos application and maintain it in a safe condition
Asbestos encapsulation is not a viable option for asbestos containing materials that are beginning to crumble and deteriorate. Applying the sealant on the material can only make the asbestos loose and facilitate the release of the fibres into the air. Using a penetrating sealant may also make it difficult to remove the asbestos containing material, should you decide upon that later on in the future. Additionally, the encapsulant should be checked and inspected from time to time as it may deteriorate over time.
