The purpose of this study is to contribute to the enhancement of technology in domestic related fields through the completion of soil material development and manufacturing technology using recycled materials. Especially, it is important to make the rooftop landscaping easily accomplished by the landlord himself by simplifying manufacturing and construction. I have. The results of the study are as follows. 1) It is considered that the development of lightweight block for vegetation will contribute to the expansion of demand for the industrialization of native plants including rhizome and plants. 2) The rooftop greening absorbs heavy metals such as carbon dioxide, nitrogen compounds, benzene, and dust and purifies the air by releasing oxygen. Therefore, this study will also help secure the rooftop green space. 3) The rooftop greening seems to be effective in reducing water pollution by filtering the initial rainfall through the soil layer. Soil on the roof also rust will serve to reduce the noise by crushing to absorb sound waves. 4) The rooftop greening soil layer will have the effect of improving the durability of the building by protecting the waterproof layer by acid rain and ultraviolet rays and preventing the aging of concrete, and the durability of the concrete surface under the rooftop greening will be improved by virtue of no temperature change.
