Product Description
Geotextile fabric is a high-performance permeable geosynthetic material manufactured from synthetic fibers through needle punching or weaving processes. It is widely used in civil engineering and construction projects due to its excellent mechanical and hydraulic properties.
The finished product is cloth-like, with a typical width ranging from 1 to 9 meters and lengths between 50 to 100 meters. Geotextiles are categorized into woven geotextiles and nonwoven geotextiles, including filament and short-fiber types, to meet different engineering requirements.
Thanks to its superior permeability and strength, geotextile fabric plays a critical role in enhancing soil stability, preventing erosion, and improving drainage efficiency.
Key Features
- High Tensile Strength: Maintains strong mechanical performance in both dry and wet conditions
- Excellent Permeability: Allows water flow while retaining soil particles
- Corrosion Resistance: Resistant to acids, alkalis, and long-term soil/water exposure
- Anti-Aging & Durable: UV resistant and long service life
- Biological Resistance: Not affected by microorganisms or insects
- Lightweight & Flexible: Easy transportation and installation
- Wide Range of Specifications: Available in various widths and weights
Product Functions
- Filtration: Prevents soil particles from migrating while allowing water to pass
- Drainage: Efficiently channels water flow within soil structures
- Separation: Keeps different soil layers from mixing
- Reinforcement: Improves load-bearing capacity of soil
- Protection: Prevents erosion and mechanical damage
Applications
Geotextile fabric is widely used in various infrastructure and geotechnical projects
- Soil separation and filtration layers
- Drainage systems for landfills, mines, and foundations
- Riverbank and slope erosion protection
- Reinforcement of roads, highways, railways, and airport runways
- Ground stabilization in soft soil and swamp areas
- Asphalt pavement crack prevention
- Frost protection and insulation layers
