Geocomposite PET Geogrid Thermal Bonding Nonwoven Fabric By Glue
Composite Geogrid Road Pavement Reinforcement
Geocomposite PET Geogrid Thermal Bonding Nonwoven Fabric Product
Overview
This polyester (PET) geogrid composite integrates a high-strength
PET geogrid with a nonwoven geotextile (typically PP or PET,
100–300 g/m²) to provide reinforcement, separation, and filtration
in a single material.
Geocomposite PET Geogrid Thermal Bonding Nonwoven Fabric Key
Features & Benefits
✅ High Tensile Strength – PET geogrid offers 30–500 kN/m tensile
strength with low creep (<2% after 50 years).
✅ Superior Filtration – Nonwoven layer prevents soil migration
while allowing water flow.
✅ Chemical & UV Resistant – PET resists acids/alkalis (pH 2–12),
while UV-stabilized nonwoven extends lifespan.
✅ Flexible & Durable – Adapts to uneven terrain, ideal for
embankments and slopes.
Yixing Shenzhou Composite geogrids are essentially geogrids that
are combined with other materials, typically geotextiles, to
provide enhanced functionality and performance. Common types
include uniaxial, biaxial, and triaxial composite geogrids, which
utilize different directional strengths in their construction.
These composites are often made with materials like polypropylene
(PP), high-density polyethylene (HDPE), and polyester (PET).

Why need to choose Composite Geogrids?
Improved Soil Reinforcement:
The combination of the geogrid and geotextile enhances the strength
and durability of the reinforced soil.
Increased Drainage:
Geotextiles can aid in drainage within the soil mass, preventing
water buildup and potential issues.
Enhanced Filtration:
Geotextiles can act as a filter, preventing fine soil particles
from moving through the structure, maintaining stability.
Crack Control:
In pavement applications, composite geogrids can help to prevent or
minimize crack propagation
Versatility:
They are suitable for various applications, including road
construction, slopes, retaining walls, and landfills
