A low-cost, low-maintenance greening method using "Non-Rotting Bark Soil E Soil," a building material made from 100% natural materials with specially processed bark from cedar and cypress trees.
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 bark of cedar and cypress, and is a 100% natural recycled building material. The characteristics of "E Soil" are as follows: 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 the bark of cedar and cypress 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 it easy to install 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 can be kept shallower than usual, while sufficiently storing and supplying oxygen, water, and nutrients to plants, promoting good 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 almost eliminated, enabling low maintenance.

basic information
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 bark of cedar and cypress, 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 suppresses the growth of root rot fungi and other pathogens in the soil, thereby reducing the incidence of diseases in grass and flowers. 2. Since the bark of cedar and cypress 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 (40 kg/m² when dry). 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 methods. 5. Due to its high gas phase ratio, the soil thickness can be shallower than usual, while still storing and supplying sufficient oxygen, water, and nutrients to plants, promoting healthy 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.

Company information
Our company offers suitable proposals and construction for buildings, focusing on window glass shading coatings "ZEROCOAT," removable heat-shielding sheets for window glass "ZEROSHEET," as well as rooftop greening and heat-shielding paints, to protect buildings from summer heat and suppress indoor temperature rise. After installation, it is possible to significantly contribute to energy savings by reducing both air conditioning usage and CO2 emissions.
