China PET Polyester Filament Nonwoven Geotextile ManufacturerApplication:
1. Reinforcement effect: Used in rock engineering such as highways, railways, airports, stone dams, slope embankments, retaining walls, and embankments, to disperse soil stress, increase soil modulus, limit soil slip, and improve stability.
2. Protection function: prevent the embankment from being washed away by wind, waves, tides, and rain, and use it for bank protection, slope protection, bottom protection, and soil erosion prevention.
3. Reverse filtration: Used as a filter layer for embankments, dams, rivers, and coastal rocks, soil slopes, and retaining walls, to prevent sand particles from passing through and allow water or air to pass freely.
