Asphalt Coated Fiberglass Composite Geogrid Geotex Geomat Geogrid
Composite
Composite Geogrid is a high-performance geosynthetics composed of a
variety of materials, mainly used for foundation reinforcement,
soil stabilization and structural enhancement in civil engineering.
Definition and Types
Material composition
Geogrids are usually made of a polymer matrix (such as
polypropylene, polyester) combined with reinforcing materials
(glass fiber, steel, etc.). Common types include:
Glass fiber composite grid: With glass fiber as reinforcement, it
has the characteristics of high tensile strength and acid and
alkali resistance, and is often used in pavement engineering.
Polyester/polypropylene composite grid: A mesh structure is formed
by weaving or welding process, which is used for reinforced
retaining walls or slope protection.
Structural design
It is divided into two-dimensional plane grid or three-dimensional
structure, and the mechanical properties are optimized through the
synergy of materials.

Manufacturing process and performance characteristics
Production process
Thermoplastic molding: forming a grid structure through
high-temperature molding or ultrasonic welding, such as the rib
welding process of steel-plastic grid.
Woven composite: weaving fiber materials (such as glass fiber) with
polymer substrates and coating them with resin to enhance
durability.
Key performance
High strength: tensile strength can reach 30-200 kN/m, which is
better than single material grid.
Corrosion resistance: suitable for engineering scenarios in acidic
and alkaline environments or long-term exposure.
Water permeability and reinforcement: allowing water to pass
through while enhancing soil stability and preventing landslides.
Application areas of composite geogrid
Water Conservancy and Flood Control Engineering
1. Dam anti-seepage and reinforcementCombined with geomembrane, it forms a composite anti-seepage layer,
improves the flood resistance of dams, and reduces the risk of
leakage.
2. River management and slope protectionApplied to river slope protection, breakwaters, etc. to prevent
soil erosion and enhance the stability of bank slopes.
3. Reservoir and wharf constructionUsed for reservoir foundation reinforcement and wharf cargo yard
foundation treatment to improve bearing capacity and anti-scouring
ability.
Municipal and Airport Engineering
1. Airport runways and parking lotsEnhance the bearing capacity of the runway foundation and reduce
deformation caused by aircraft takeoff and landing. It is also used
for foundation stabilization of large parking lots.
2. Municipal roads and bridges
In urban roads, bridges and tunnel projects, it improves the
compressive strength of the roadbed and reduces the frequency of
road maintenance.
Environmental and Ecological Engineering
1. Isolation of landfill and pollution
As an isolation layer of polluted sites, it prevents the spread of
harmful substances and is also used to reinforce the foundation of
landfills.
2. Soil and water conservation and greening projects
Used in conjunction with grass-planting net mats in ecological
slope protection to reduce soil erosion and promote vegetation
growth.
