Asbestos
Encapsulation

Repair or encapsulation of Asbestos Containing Materials (ACMs) may be a more suitable alternative to removal. Our team of friendly experts at Remco have the knowledge and experience to help you choose the right course of action.

Asbestos Containing Materials (ACMs) should always be kept in a good, sealed condition and protected from damage or disturbance. If your asbestos is not properly sealed or has suffered minor damage or wear over the course of time, it might be more appropriate or more cost effective to have the material encapsulated and display asbestos warning signs, rather than having the material removed. 

When considering encapsulation rather than removal, possible future damage to the ACM must be taken into account, e.g. from structural movement; vibration; vandalism; or from tools and equipment, or vehicle activity such as fork-lift trucks. The need for future maintenance work must also be considered.

Methods

What Is Asbestos Encapsulation?

Asbestos encapsulation can be defined as the application of an impervious material, which is secured over or around an ACM. It is designed to prevent the release of asbestos fibres under normal and 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.

Mechanical Encapsulation

E.g. by use of board or sheet materials to over-clad or box-in the asbestos material.

High Build Elastomeric Coating

A liquid encapsulant like paint applied in several layers (such as ‘Idenden ET150’) which provides impact resistance and is flame resistant.

Penetrating Encapsulates

Suitable for encapsulation of sprayed coatings, insulation, boards etc. (such as ‘Incorez’ or ‘Serpiflex’). Spray applied encapsulants are available which will penetrate friable ACMs.
