Seeding and planting method and seeding and planting structure for wall surface of concrete structure or soilless base rock

TLDR: In this paper, an impervious sheet and a water absorbing mat are stuck to the vertical wall surface formed of concrete, and then a water permeable concrete material is spray to the wall surface to create a water retentive growth base material.

Abstract: PROBLEM TO BE SOLVED: To provide a means for easily carrying out seeding and planting work to a concrete wall surface and enhancing the appearance of the wall surface in harmony with natural environment. SOLUTION: An impervious sheet 2 and a water absorbing mat 3 are stuck to the vertical wall surface 1 formed of concrete. A water permeable concrete material is then sprayed to the vertical wall surface 1 to form a water permeable concrete layer 4. A water retentive growth base material 5 is filled in cavity parts in the water permeable concrete layer 4. A vegetation base material containing plant seeds and the like is further sprayed onto the water permeable concrete layer 4 to form a vegetation base material layer 6. Plants then grow to plant the vertical wall surface 1. Since this seeding and planting work is performed mainly by spraying, construction is extremely easy, and since water is retained in the water permeable concrete layer 4 by the water retentive growth base material 5, the growth of plants is hastened.
