The asbestos-enclosed solidification treatment material is mainly a first asbestos treatment material having a high permeability obtained by mixing an alkaline aqueous solution or slurry containing metal ions, vegetable or animal oil, and vegetable or animal glue. And, mainly, an alkaline aqueous solution or slurry containing metal ions, vegetable or animal oil, vegetable or animal glue, organic or inorganic fiber, and aggregate are highly sealed. It consists of a combination with a second asbestos treatment material.

  Since this first asbestos treatment material is made of a highly permeable solution, it gradually penetrates into the building structure by applying, spraying or injecting it onto the surface of the building structure containing asbestos fibers. Then, after drying, an organometallic compound is formed. Since the 2nd asbestos processing material consists of a highly sealing solution which has lime as a main component, it sprays on the building structure after processing of the 1st asbestos processing material, and calcium ion is asbestos fiber. It is made to act on the surface and is firmly bonded to asbestos fibers, and limestone is formed over time by the action of carbon dioxide in the atmosphere.
