Reinforcement Fiberglass Geogrid Key Characteristics and Advantages
High Tensile Strength: Offers significant strength-to-weight ratio.
Low Creep: Unlike some polymers, fiberglass exhibits minimal
elongation under
long-term load, making it ideal for permanent structures.
Excellent Durability: Resistant to chemical and biological
degradation from soil,
alkalis, and moisture. The coating provides UV resistance during
installation and service.
Biaxial Reinforcement: Most fiberglass geogrids are designed to
have near-equal strength in
both the machine (longitudinal) and cross-machine (transverse)
directions, making them ideal
for stabilizing areas where loads come from multiple directions.
How Does Reinforcement Fiberglass Geogrid Work?
The principle is based on tensile strength and friction/interlock:
1. 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.
2 .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.
3 .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). |

quick deployment
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.
