PROBLEM TO BE SOLVED: To prevent generation of remaining water between a stabilizing layer formed on a slant surface and a substrate by forming the layer to have a water penetration characteristic by a method of blowing a material composed of aggregate material having a specified grain size coated with a self hardening adhesive to a work execution surface through a nozzle. SOLUTION: Aggregate materials 2 are quantitatively fed to a hopper 7 continuously through a measuring unit 5 from a hopper 3, and pressure fed to a mixer 11 by the air from a compresser. Then, a self hardening type adhesive 14 prepared by the hopper 9 and a grout mixer 8 is presssure fed to the mixer 11 by a grout pump 19, the air of the compresser 12 is fed to the mixer 11, and materials A composed of the aggregate materials coated with the adhesive 14 are sprayed or blown to a work execution surface from a nozzle 18. The aggregate materials are composed of screened sand whose grain size is 5-15 mm, and in the case of applying green plants on the work execution surface, those of screened crushed stones, screened sand and gravels or artificial lightweight rough aggregate materials are used. The adhesive 14 is formed of cement paste into which reinforceing materials or mixing materials are mixed properly. Accordingly, the purpose is attained.
