Biaxially – Stretched Plastic Geogrid
Short Description:
It is a new – type geosynthetic material. It uses high – molecular polymers such as polypropylene (PP) or polyethylene (PE) as raw materials. The plates are first formed through plasticizing and extrusion, then punched, and finally stretched longitudinally and transversely. During the manufacturing process, the high – molecular chains of the polymer are re – arranged and oriented as the material is heated and stretched. This strengthens the connection between the molecular chains and thus increases its strength. The elongation rate is only 10% – 15% of that of the original plate.

Performance Advantages
High Strength: Through a special stretching process, stress is evenly distributed in both the longitudinal and transverse directions. The tensile strength is significantly higher than that of traditional geotechnical materials and can withstand large external forces and loads.
Good Ductility: It can adapt to the settlement and deformation of different foundations and shows good adaptability in various engineering environments.
Good Durability: The high - molecular polymer materials used have excellent chemical corrosion resistance and ultraviolet resistance and are not easily damaged during long - term use under harsh environmental conditions.
Strong Interaction with Soil: The mesh - like structure enhances the interlocking and restraining effect of aggregates and significantly increases the friction coefficient with the soil mass, effectively preventing the displacement and deformation of the soil.
Application Areas
Road Engineering: It is used for subgrade reinforcement in highways and railways. It can increase the bearing capacity of the subgrade, prolong the service life of the subgrade, prevent road surface collapse or cracking, and reduce uneven settlement.
Dam Engineering: It can enhance the stability of dams and prevent problems such as dam leakage and landslides.
Slope Protection: It helps to reinforce slopes, prevent soil erosion, and improve the stability of slopes. At the same time, it can support the slope grass - planting net mat and play a role in greening the environment.
Large - scale Sites: It is suitable for foundation reinforcement of large - area permanent load - bearing areas such as large - scale airports, parking lots, and wharf cargo yards, improving the bearing capacity and stability of the foundation.
Tunnel Wall Reinforcement: It is used to reinforce the tunnel walls in tunnel engineering and enhance the stability of the tunnel walls.
