PET polyester chips Nonwoven Geotextile Easy to construct, acid and alkali resistant For tailings ponds and landfills
Product Introduction
PET polyester chips Nonwoven Geotextile is a geosynthetic material made directly from polyester by spinning and needle consolidation. Product specifications can be selected from 100-800g/m², and the fibers are arranged into a three-dimensional structure. It has good mechanical function, good water permeability, and can resist corrosion, anti-aging. In addition, it can also adapt to the uneven base, resist the damage of external construction force, creep becomes smaller, and can maintain the original function even under long-term load.
Product Properties
Good mechanical function, water permeability, corrosion resistance, aging resistance, and can adapt to uneven base, resist construction external force damage, creep becomes smaller, even under long-term load can still maintain the original function.
Application Fields
Long fiber geotechnical fabric is widely used in the field of infrastructure construction, including but not limited to the following aspects:
Hydraulic Engineering: Filtering for dams and slope protection, isolation and seepage prevention in canals.
Traffic Engineering: Basic isolation, drainage, and reinforcement of roadways, railways, and airport runways; backfilling and slope protection.
Harbor Engineering: Soft foundation treatment, beach revetment, reinforcement of seaport wharves and breakwaters, drainage.
Environmental Engineering: Impervious Barrier for Landfills
Specifications and Standards
Construction and Maintenance
During the construction process, the long fiber geotechnical fabric needs to be laid and fixed correctly to ensure the effective play of its functions. After construction, regular inspection should be carried out to ensure its integrity, and any damaged parts should be repaired in time to maintain its long-term effectiveness.To sum up, the long fiber geotechnical fabric plays a crucial role in modern engineering construction due to its excellent performance and wide range of application fields.
