Superior Flow Rate - 120+ L/m²/s permeability for rapid drainage
Precise Filtration - Controlled AOS retains soil while allowing water flow
Extreme Durability - UV-resistant PP with ≥8 kN/m tensile strength
Multi-Soil Adaptability - Works in sandy to clayey conditions
Introduction:
Engineered for superior performance, our High-Flow Filtration Geotextile Filter represents the pinnacle of drainage technology in modern civil engineering. This advanced filtration fabric combines exceptional flow capacity with precise particle retention, making it ideal for critical infrastructure projects. Manufactured from premium UV-stabilized polypropylene, our geotextile filter delivers unmatched durability in demanding environments from landfill liners to coastal protection systems. With specialized needle-punching technology, we achieve optimal porosity (120+ L/m²/s) while maintaining strict AOS (Apparent Opening Size) control for effective soil retention. The product has become the preferred choice for engineers worldwide, with over 500,000 square meters shipped annually to major infrastructure projects across three continents.
Key Features
1. Superior Hydraulic Performance:
Our proprietary manufacturing process creates a three-dimensional fiber matrix that maintains exceptional flow rates (120+ L/m²/s) even under heavy loads, outperforming conventional geotextiles by 40-60%. The optimized pore structure prevents clogging while effectively retaining soil particles as small as 0.075mm.
2. Engineered Durability:
The UV-stabilized polypropylene fibers provide outstanding resistance to environmental degradation, with tensile strength maintained at ≥8 kN/m after accelerated aging tests. Special needle-punching technology enhances dimensional stability, preventing fabric distortion during installation.
3. Adaptive Filtration:
Precisely controlled AOS ratings (70-100) ensure optimal performance across various soil types, from coarse sands to silty clays. The gradient density structure automatically adjusts to different hydraulic gradients, maintaining filtration efficiency throughout the project lifespan.
