Definition

A method of asbestos abatement that involves treating asbestos-containing materials with a sealant to prevent fiber release. Encapsulants penetrate the material or create a protective coating that binds the fibers together. This method is less expensive and disruptive than removal but requires ongoing monitoring and maintenance. Suitable only for materials in good condition that will not be disturbed.
