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.
