Plastic Mesh Grid Biaxial Geogrid Made Of Polypropylene (PP) For Soil Stabilizer On Roads

Definition and Classification of Plastic Geogrids
Plastic geogrids are geosynthetics with a grid-like structure, made from high-molecular-weight polymers through processes such as extrusion, punching, and stretching. They are primarily used for reinforcement, strengthening, and protection in civil engineering. Depending on the direction of stretching, they can be divided into two categories: unidirectional and biaxially oriented geogrids.

Characteristics and Applications of Unidirectional Plastic Geogrids

• Materials and Structure: Made from high-density polyethylene (HDPE), it is extruded into thin sheets, punched, and then stretched longitudinally, forming an oblong mesh structure with oriented, linearly arranged polymer molecules.
• Main Characteristics: It offers extremely high longitudinal tensile strength and rigidity, excellent creep resistance, and effectively transfers soil stress and spreads loads. The mesh's interlocking effect with the soil improves engineering stability.

Typical Applications:

• Strengthens roadbeds, increasing bearing capacity and extending service life, while reducing rutting and cracking.
• Reduces earth pressure in retaining walls, saving 30%-50% in project costs.
• Adding it to highway pavement can reduce structural layer thickness by up to 36% and delay cracking by 3-9 times.

Characteristics and Applications of Biaxially Stretch Plastic Geogrids

• Materials and Structure: Made from polypropylene (PP) or polyethylene (PE), the material is extruded into sheets, punched, and then stretched longitudinally and transversely to create a high-strength biaxial grid structure.
• Main Features: High tensile strength in both the longitudinal and transverse directions, making it suitable for large-scale, permanent load-bearing applications. Its high coefficient of friction with the soil provides a synergistic interlocking effect.

Typical Applications:

• Permanent foundation reinforcement for large airports, parking lots, and cargo yards.
• Embankment, slope protection, and tunnel wall reinforcement. Combined with shotcrete anchoring, it can shorten construction time by more than half.
• Replacing traditional metal mesh in underground coal mine false roofs, reducing maintenance costs.

Construction advantages of plastic geogrid :

• Strong adaptability: Suitable for various soil types, eliminating the need for sourcing materials from other locations, saving labor and time.
• Convenient construction: Widths up to 6m are possible, enabling efficient laying, requiring only manual fixing followed by compaction with a roller.
• Cost-effectiveness: Reduces structural layer thickness, shortens construction time, and reduces maintenance costs, ultimately reducing overall construction costs by 20%-50%.

Case Studies :
Qinghai-Tibet Highway: Uniaxial HDPE geogrids reduced frost heave by 60%

Hong Kong-Zhuhai-Macao Bridge: Biaxial grids enhanced seabed foundation stability.

“Plastic geogrid is a strong plastic mesh used to reinforce soil and make roads, slopes, and foundations more stable and long-lasting.”
