High Strength HDPE Uniaxial Plastic Geogrid Mesh Reinforcement
Retaining Wall Soil
Description:
Yixing Shenzhou HDPE (High-Density Polyethylene) Geogrids are engineered polymeric grids used for soil reinforcement, slope
stabilization, and load distribution in civil engineering projects.
Manufactured through extrusion, punching, and uniaxial/biaxial stretching, they provide high tensile strength with minimal deformation.
Technical Specifications:
| Parameter | Uniaxial Geogrid | Biaxial Geogrid |
|---|
| Tensile Strength | 20-200 kN/m (MD) | 15-50 kN/m (MD/CD) |
| Aperture Size | 25-150mm | 15-100mm |
| Roll Dimensions | 2-6m width x 50-100m | 2-5m width x 50m |
| Temperature Range | -60°C to +80°C | -60°C to +80°C |
Applications :
1. Reinforced Soil Structures
Retaining walls (up to 30m height)
Steep slope stabilization (up to 70°)
2. Transportation Infrastructure
Road and railway embankments
Airport runways and taxiways
3. Mining & Industrial
Tailings dam reinforcement
Heavy-duty access roads
4. Coastal & Waterfront
Revetment protection
Breakwater foundations
5. Landfill Engineering
Liner system reinforcement
Final cover systems
Case Studies :
Qinghai-Tibet Highway: Uniaxial HDPE geogrids reduced frost heave
by 60%
Hong Kong-Zhuhai-Macao Bridge: Biaxial grids enhanced seabed
foundation stability.
Installation Guide :
Subgrade Prep: Compact to ≥95% Proctor density; remove sharp
objects.
Laying:
Uniaxial: Align high-strength direction with load.
Biaxial: Overlap ≥300mm at edges.
Backfilling: Use granular fill in ≤300mm lifts.
