The present invention provides a method for stabilizing irregular structures such as rock structures in mines and in construction sites as well as other rock and concrete structures. The method comprises concurrently heating and mixing a mixture of polyoxypropylene diamine with an aromatic diamine liquid, mechanically purging the mixture under pressure and applying the purged mixture to a desired irregular structure. The invention also provides a weather resistant and anti-corrosive polyurea coating material as a fibrous mesh, liquid film, geotextile mat and foam for stabilizing rock, concrete and molding tool structures.
