Polyster filament geotextile is spinning needle directly adoping the approach of polyster and can choose any one from the specifications of 80-800g/m2.
It is a geosynthetic material in geotechnical engineering and civil engineering applications. It uses polyester filament yarn into a network and method of consolidation. And the fibers is arranged in its three-dimensional structure. In addition to good mechanical properties, it also has a good vertical and horizontal drainage performance and to extend good performance and high resistance to biological, acid,chemical stability,such as anti-aging properties. As the same time, it has a wide aperture range, the pore distribution of twists and turns, excellent penetration performance and filter performence.
Features: Soil erosion; Water soil formed guiding; Soil tensile strength and resistance enhancing; To prevent soil by external force and destruction; To prevent the sand, soil and concrete mixed between layers; High permeability; Corrosion Resistance.
