A low-cost, low-maintenance greening method using "E-Soil," a 100% natural building material made from specially processed bark of cedar and cypress that does not rot.
The Obayashi-style greening method is characterized by the use of "E Soil," a non-decaying bark soil developed by Obayashi Environmental Technology Research Institute Co., Ltd. "E Soil" is made from specially processed cedar and cypress bark and is a 100% natural recycled building material. The features of "E Soil" are as follows: 1. It has the natural antibacterial and insect-repelling properties of cedar and cypress, which helps suppress the growth of root rot fungi and other pathogens in the soil, thereby reducing the incidence of diseases in grass and flowers. 2. Since cedar and cypress bark does not decompose, it maintains its fibrous state for a long time, eliminating the need for soil replacement or addition. 3. It is lightweight, allowing it to accommodate the load-bearing capacity of existing structures. 4. It does not get blown away by the wind or washed away by rain, making installation simple as it only requires placing "E Soil." There is no need for the drainage layer typically required in conventional greening. 5. Due to its high gas phase ratio, the soil thickness can be shallower than usual, while still adequately storing and supplying oxygen, water, and nutrients to plants, promoting strong root growth and supporting plant development over many years. These features allow for low-cost installation, and after installation, the use of pesticides and other chemicals is greatly reduced, enabling low maintenance.

basic information
The Obayashi-style greening method has a significant feature of using "E Soil," a non-decaying bark soil developed by Obayashi Environmental Technology Research Institute Co., Ltd. "E Soil" is made from specially processed cedar and cypress bark and is a 100% natural recycled building material. The characteristics of "E Soil" are: 1. It has the natural antibacterial and insect-repelling properties of cedar and cypress, which suppresses the growth of root rot fungi and other bacteria in the soil, thereby reducing the occurrence of diseases in grass and flowers. 2. Since cedar and cypress bark does not decompose, it maintains its fibrous state for a long time, eliminating the need for soil replacement or addition. 3. It is lightweight, allowing it to meet the load-bearing capacity of existing structures (40 kg/m² when dry). 4. It does not blow away in the wind or wash away in the rain, making installation easy by simply placing "E Soil." There is no need for the drainage layer typically required in conventional greening. 5. Due to its high gas phase ratio, the soil thickness can be shallower than usual, while still adequately storing and supplying oxygen, water, and nutrients to plants, promoting strong root growth and supporting plant development over many years. These features allow for low-cost installation, and after installation, the use of pesticides and other chemicals is greatly reduced, enabling low maintenance.
