Short Filament Pet Polyester Geotextile Nonwoven Black And White
Color Geosynthetic Materials Road Geotextiles
Long fiber geotextile fabric is prescribed by the state, a kind of
new construction material that used for civil engineering. And the
filament fibers are arranged into reticular through different
equipment and technology. Then through the acupuncture craft, let
different fibers interwoven with each other, mutual entanglement,
fixed and make the fabric standardizing.
This is in order to make the fabric soft, plump, thick, stiff and
achieve different thickness to meet the using requirements. In
addition, its relative product is short fiber geotextile fabric,
but the tensile strength of the filament is higher than that of the
short fiber.

Polyester Filament Needle Punched Geotextile is mainly used in the
following projects: in the highway (including temporary road)
railway, embankment, earth rock dam, airport, sports field and
other projects, to strengthen the weak foundation at the same time
play the role of isolation and filtration.
Railway engineering, water conservancy engineering, landfill, bank
slope protection, horticulture engineering, agricultural
engineering, sports venues. Separation and reinforcement in road
and railway construction.Prevention of soil movement in erosion
control measures
Short Filament Polyester Geotextile Construction phase: Laying the foundation for stable use
1. Pre-construction Preparation
Site Clearance: Thoroughly remove sharp debris such as stones,
rebar, and glass from the construction area. Level the ground and
prevent protrusions from puncturing the geotextile.
Product Inspection: Verify that the geotextile specifications and
quantity match the test report. Inspect the appearance for damage,
mold, and unusual odors.
Tool Preparation: Prepare tools such as a heat bonding machine,
sewing machine, measuring tape, and edge stones. Ensure the
splicing equipment is functioning properly.
2. Standardized Construction Process
Laying Operation: Lay the geotextile in a "bottom-up, slope-first,
bottom-later" sequence to avoid excessive tension leading to stress
concentration. Allow for 5%-10% expansion and contraction.
Splicing Process: Use heat bonding or sewing for splicing. The
overlap width should be ≥10cm. The heat bonding temperature should
be controlled at 150-180℃ to ensure no delamination or cracking at
the splice.
Protective Covering: Within 48 hours of completion, promptly cover
the geotextile with a protective layer of soil, gravel, or
geomembrane to prevent UV exposure.
Mechanical Operations: Construction machinery must operate on the
protective layer. If direct contact with the geotextile is
necessary, wooden planks must be laid down to distribute pressure;
dragging or rolling is prohibited.
3. Construction Quality Acceptance
Visual Inspection: No damage or wrinkles; laid flat; joints neat
and secure.
Performance Testing: Randomly sample and test the joint strength;
it must reach at least 80% of the parent material strength; test
the permeability coefficient; it must meet design requirements.
Hidden Works Records: Record in detail the laying range, joint
locations, coverage thickness, etc., and archive for future
reference.
