Geotextile, also known as short fiber geotextile, is a permeable geosynthetic material made by needle-punching or weaving synthetic fibers. The finished product is in the form of fabric, typically 1-6 meters wide and 50-100 meters long. Short fiber geotextile has excellent mechanical properties, good permeability, and is resistant to corrosion and aging. It serves functions such as isolation, reverse filtration, drainage, protection, stabilization, and reinforcement, and can adapt to uneven subgrades. It can withstand external construction forces and has low creep, maintaining its original functions under long-term loads.
Performance Features:
Excellent flexibility, easy to install, with good permeability, filtration, and isolation properties.
Application:
Reverse filtration and isolation drainage maintenance for road, railway, embankment, reclamation, and other engineering projects.
