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.
