A process is described for the removal of an asbestos-filled lining or coating applied on a surface of a building. According to the process, high-pressure water is jetted out against the lining or coating while mechanically rubbing the lining or coating, thereby separating the lining or coating as fragments from the surface. The fragments are drawn together with the surrounding air and are then collected by means of a dust collector. Also described is a water jet device suitable for use in the removal of an asbestos-filled lining or coating. The device includes at least one rotary shredding blade to be driven by a motor in use, at least one water jet nozzle provided near the center of rotation of the blade, a cylinder surrounding the blade and nozzle in such a way that high pressure water is jetted out from the nozzle against the lining or coating and the blade is brought into frictional contact with the lining or coating, whereby the lining or coating is separated as fragments, and an exhaust pipe connected to the cylinder.
