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.
