Environmental Protection

Most environmental protection projects, such as metal ore tailings dams, heap leaching fields, landfills, and ash dam pools, are undertaken in alkaline condition. Therefore, the polypropylene spunbond needle punched geotextile is the only choice. Whereas, a Polyester geotextile will be gradually decomposed under alkaline conditions with strength decreasing sharply, and then safety risks to the project may occur accordingly. With stable chemical performance, polypropylene spunbond needle punched geotextiles can highly keep the quality of the construction, avoid risks to the project, and reduce the maintenance cost.
