Geotextile geobag can completely replace stone, cement and other materials, which can greatly reduce the project cost. After construction, the slope has vegetation covered surface, which makes the excavated slope achieve greening effect and form natural ecological slope. It has the filtering function of water permeability and impervious soil. The slope formed in this way has high water permeability, and has strong protection and stability effect on soil loss, local mud (soil) rock flow and slope collapse.
