What is a Reinforcement Fiberglass Geogrid?
A Reinforcement Fiberglass Geogrid is a geosynthetic material manufactured from
fiberglass filaments, woven or knitted into a grid-like structure and then coated with
a protective polymer (like PVC or acrylic). Its core purpose is to provide tensile strength to soil,
aggregate, or other construction materials that are strong in compression but weak in tension.
How Does Reinforcement Fiberglass Geogrid Work?
The principle is based on tensile strength and friction/interlock:
Tensile Strength:
Soil and aggregate are strong under compression (they can bear weight) but have virtually
no tensile strength (they can't resist stretching or pulling forces). The fiberglass geogrid,
with its high tensile strength (e.g., 50 kN/m, 100 kN/m, etc.), provides this missing property.
Mechanical Interlock:
The open apertures (the "holes" in the grid) allow the soil or aggregate particles to partially
penetrate and lock into the grid. This creates a strong mechanical connection.
Stress Distribution:
When a load is applied (e.g., from a truck wheel), the soil tries to deform laterally.
The geogrid mobilizes its tensile strength to absorb these lateral forces,
effectively "holding the soil together" and distributing the load over a much wider area.
This reduces stress on the weak subgrade and prevents excessive deformation (like rutting).

Reinforcement Fiberglass 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.
Reinforcement Fiberglass 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.
