Asbestos is a mineral material characterized by a fibrous structure that, until a few years ago, was used in the building industry because of its high mechanical strength and chemical properties. Asbestos fibers are extremely thin, up to 1300 times smaller than a human hair, so they are extremely volatile and easily inhalable.
Because of the carcinogenicity of asbestos fibers, its use has been outlawed since 1992. Law No. 257/92 lays down the terms and procedures for the disposal of inert and asbestos still present in buildings.
Systems for the encapsulation of asbestos usually consist on the application of resins and coatings that can totally cover the surface and fully encapsulate asbestos, completely preventing the dispersion of the fibers in the air.
