Product Introduction

Polyester filament geotextile is a type of geosynthetic textile featuring a three-dimensional porous structure. It is manufactured using PET or PP as raw materials through a production process that integrates melt spinning, air-laid web formation, and needle-punching consolidation.

This geotextile exhibits excellent mechanical properties and high water permeability. It is resistant to corrosion and aging, and performs multiple functions including isolation, reverse filtration, drainage, protection, stabilization, and reinforcement. It adapts well to uneven subgrades and withstands damage during construction. The material demonstrates low creep, maintaining its original functionality under long-term loading. Even when briefly exposed to temperatures as low as -20°C, its performance remains virtually unchanged. Extensive testing and practical applications have proven that filament geotextile offers long-term corrosion resistance against various natural soils, moisture, and microorganisms.

Function and Use

• Water Conservancy Projects: Sea dikes, river embankments, lake levees; reservoir reinforcement; reclamation works; flood emergency response.

• Highway, Railway, and Airport Engineering: Soft ground improvement; slope protection; anti-reflective cracking layers in pavements; drainage systems; greenbelts and dividers.

• Power Engineering: Foundation works for nuclear power plants; ash dam projects for thermal power plants; hydropower station projects.

• It is widely used for reinforcement, stabilization, filtration, and separation in roads, railways, dams, coastal tidal flats, and other civil works.

• Filament geotextile is particularly suitable for use in saline-alkali marshes and landfill sites.
