FG Biaxial Grid 100 Asphalt Pavement Knitted Glass Fiber Geogrid
Reinforce Soft Soil Road Construction
What is a Glass Fiber Geogrid?
A Glass Fiber Geogrid is a geosynthetic material made from
high-strength
glass fiber filaments coated with a protective polymer (like PVC or
acrylic).
These filaments are woven or knitted into a grid-like structure,
consisting
of ribs (the longitudinal and transverse elements) with large,
regular openings called apertures.
Its primary function is to function as a reinforcement material
within soil, asphalt, or other granular
materials. It does not act as a separator or filter but distributes
loads and provides tensile strength
to a system that would otherwise have none.
Glass Fiber Geogrid Key Components and Manufacturing
Glass Fiber Filaments: The core material. Glass fibers are known
for their exceptionally high tensile strength
and low elongation (they are very strong but don't stretch much).
Coating: The glass fibers are sensitive to abrasion and the
alkaline environment of soil and cement.
A specialized polymer coating is applied to:
Protect the fibers from mechanical damage.
Protect against chemical degradation.
Improve the bond (friction) between the grid and the surrounding
soil or asphalt.
Glass Fiber Geogrid Key Properties:
Aperture Size:
Typically ranges from 20x20 mm to 40x40 mm, optimized for optimal
interlock with common aggregate sizes.
Coating:
Coated with a polymeric material (e.g., PVC) to protect the glass
fibers from abrasion and
damage during installation and to provide UV resistance.

Glass Fiber Geogrid Key Benefits:
✔ Optimal Load Distribution – Reduces stress and prevents
reflective cracking
✔ Asphalt-Compatible – Bitumen-coated for superior adhesion in
paving applications
✔ High Tensile Strength – 50 kN/m in both directions (longitudinal
& transverse)
✔ Corrosion & UV Resistant – Long-lasting durability in harsh
conditions
✔ Easy Installation – Flexible, lightweight, and roll-form for
quick deployment
Glass Fiber Geogrid Applications:
1.Road and Pavement Reinforcement:
Laid on soft subgrade before placing the aggregate base course.
It reduces rutting, extends pavement life, and allows for a thinner
base layer, saving cost.
2.Soil Stabilization:
Used to build stable working platforms on very soft soils (like
clay or peat),
allowing construction equipment to operate.
3.Asphalt Overlay Reinforcement:
A specialized application where a fiberglass geogrid is embedded in
asphalt to retard reflective cracking from old pavement layers.
4.Landfill and Embankment Support:
Provides tensile strength to soil structures.
5.Parking Lots and Access Roads:
A very common application for this strength class.
Glass Fiber Geogrid Key Considerations and Potential Downsides :
Not a Fix for Structural Failure:
If your old driveway is failing due to a poor base
(e.g., sinking, severe rutting), a geogrid will not help. The
underlying base must be sound and stable.
Proper Thickness is Critical:
Paving too thin of an asphalt layer (e.g., 1.5-2 inches) over the
grid will not
provide enough material to interlock properly and can lead to
raveling (the asphalt breaking apart around the grid).
Cost:
It adds to the initial cost of the driveway project due to the
material cost and specialized installation knowledge.
Contractor Experience:
Not all asphalt contractors are familiar with the proper
installation technique for paving geogrids. It is vital to hire a
contractor who has proven experience with this specific product.
