Aperture Size 12.8mm Warp Knitted Fiberglass Biaxial Geogrid
Tensile Strength 50/100 KN Base Reinforce Parking Lots
Choose Fiberglass Biaxial Geogrid Reason :
You would select this product when you need to:
Reinforce a base course over soft ground.
Stabilize a subgrade to create a solid working platform.
Distribute loads over a wider area to prevent failure.
Reduce long-term rutting and maintenance in paved and unpaved
areas.
Achieve all of the above with a material that is strong in both
directions, highly durable, and resistant to creep.
How a Biaxial Fiberglass Geogrid Works in the Ground ?
When laid on the ground, the biaxial grid creates a coherent,
reinforced platform through two main mechanisms:
Lateral Restraint:
The grid interlocks with the aggregate base material. As traffic
loads try to push the aggregate
sideways and downwards, the geogrid locks the particles in place,
preventing this lateral movement.
Membrane Support:
The geogrid tenses up under load, acting like a taut membrane that
spreads the vertical load
(e.g., from a truck tire) over a wider area of the weak subgrade
soil. This significantly reduces the pressure on the soft soil
underneath.
Fiberglass Biaxial 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.

Fiberglass Biaxial 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
Fiberglass Biaxial 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.
Fiberglass Biaxial 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.
