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.

Asbestos Abatement
Any work done to control fiber release from asbestos-containing materials: removal, encapsulation, enclosure, or repair. Licensed contractors carry out abatement under strict safety protocols, including sealed containment, negative air pressure, full worker PPE, and certified waste disposal. The aim is to eliminate or reduce the exposure risk to building occupants and workers.
ACM (Asbestos-Containing Material)
ACM (asbestos-containing material) is any material with more than 1% asbestos by weight. At peak use, ACMs appeared in over 3,000 different products: insulation, fireproofing materials, roofing, flooring, and cement products. Buildings must be surveyed for ACMs before renovation or demolition, and any found must be managed or removed to protect occupants and workers.
