Yixing Shenzhou Geosynthetics Plastic Geogrid Uniaxial HDPE Grid Product Overview:
Plastic geogrid is a geosynthetic material made from high polymer compounds such as polypropylene (PP) or high-density polyethylene (HDPE). Produced through extrusion, punching, and stretching processes, it forms a square or diamond-shaped grid structure with excellent tensile strength and stability. Plastic geogrids are widely used in road, railway, embankment, slope protection, and foundation reinforcement projects.
Raw Materials
Polypropylene (PP): High toughness, excellent chemical and corrosion resistance.
High-Density Polyethylene (HDPE): High strength, durable, and resistant to cracking.
Additives: UV stabilizers and antioxidants for enhanced weather resistance and long service life.
Types of Plastic Geogrid
| Type | Features | Main Application |
| Uniaxial Geogrid | High strength in one direction | Roads, railways, embankments |
| Biaxial Geogrid | Balanced strength in two directions | Foundations, slopes, retaining walls |
| Steel-Plastic Composite Geogrid | Embedded steel wires for extra strength | Soft soil reinforcement, heavy-load projects |
Manufacturing Process
1.Extrusion: Raw materials are extruded into plastic sheets.
2.Punching: Regular holes are punched into the sheets.
3.Stretching:
Uniaxial Geogrid – stretched in one direction, providing high tensile strength along the longitudinal axis.
Biaxial Geogrid – stretched in both directions, ensuring uniform strength in both longitudinal and transverse directions.
4.Shaping & Cooling: Stabilizes the grid structure.
Plastic Geogrid Uniaxial HDPE Grid Applications
A. Transportation Infrastructure
Road/Railway Embankments:
Reduces aggregate thickness by 30–50% by distributing loads laterally
Delays pavement cracking by 3–9× and reduces structural layer thickness by 36%
Airport Runways: Handles heavy dynamic loads with minimal rutting
B. Retaining Structures
MSE (Mechanically Stabilized Earth) Walls:
Increases wall by 40% and reduces fill material usage 14%
Lowers maintenance costs by 20–50% compared to conventional methods
Slope Stabilization:
Reinforces steep slopes (up to 70°) and prevents erosion
C. Hydraulic & Environmental Engineering
Dam/Levee Reinforcement:
Enhances in riverbanks and coastal areas
Landfill Liners: Protects geomembranes from puncture (CBR ≥3 kN)
D. Specialized Uses Permafrost Regions:
Withstands -45°C to -50°C
Mining Tailings: Stabilizes soft subgrades under heavy machinery
