Description

  The present invention relates to a rooftop greening material for holding and growing plants such as herbs and trees for greening the rooftop or outer wall of a building, and a rooftop greening method using the same.

  In recent years, especially in urban areas, a decrease in green space, an increase in the soil and water surface concrete coverage, and an increase in energy consumption have caused the heat island phenomenon and the like, and human life is being threatened. At the same time, increasing carbon dioxide emissions and increasing air pollution are becoming issues.

  In order to solve this problem, in urban areas, the rooftops of buildings and other buildings for the purpose of heat insulation, air cooling, concrete protection, air purification, rainwater temporary storage, creation of living habitats, etc. Greening is anxious.

Currently, various researches are being conducted on rooftop greening. The main method is to add peat moss and other additives to the soil to make it lighter and then deposit it on the rooftop, and at the same time implement waterproofing and irrigation work. However, this method requires foundation work for waterproofing and irrigation on the roof and is expensive, and there are also problems in terms of retention performance and runoff resistance of lightweight soil.
As another example, vegetation mats processed into mats using materials such as urethane are also applied, but they are expensive and they use a lot of unnatural chemical products. It can be said that it is incomplete. As such an example, JP 2003-259731 A can be cited.
