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.
