By spraying of 50 mm thickness fiber soil, most of the shallow root species, such as grass species and creeper species will be established. In additional to the installation of Eco-Bag, a durable synthetic perforated bag filled with soil mix with 300 mm thickness will be installed, followed by spraying the fiber soil to cover the slope. This will provide an adequate thickness of anchor for most of the woody trees and shrub species. Most of the native species are proved to be established successfully onto the Eco-Green System on the non-soil slope.
