Geogrid

1. Subgrade Reinforcement in Road Construction

Geogrids enhance load-bearing capacity and stability in roadbeds. When installed within the subgrade, they:
✔ Restrict lateral displacement of soil particles
✔ Distribute loads evenly, reducing differential settlement
✔ Improve soft soil strength (e.g., in marshland road projects)
✔ Extend pavement service life by minimizing deformation

2. Slope Protection & Erosion Control

Used for reinforcing embankments, geogrids:
✔ Increase shear strength of slope soils
✔ Prevent landslides and soil erosion
✔ Support vegetation growth (combined with bioengineering)
✔ Stabilize steep/crumbly slopes (e.g., in mining or highway cuts)

3. Retaining Wall Reinforcement

In mechanically stabilized earth (MSE) walls, geogrids:
✔ Reduce lateral earth pressure by 30–50%
✔ Enhance structural integrity through soil-geogrid friction
✔ Allow thinner wall designs, cutting material costs
✔ Improve resistance to overturning and sliding

Technical Advantages

✅ High tensile strength (20–100 kN/m, per ASTM D6637)
✅ Chemical resistance (pH 3–11 stability)
✅ Long-term durability (>50-year design life)
✅ Cost efficiency (saves 20–40% vs. traditional methods)

Applications in Action:

• Highway embankments (e.g., reinforced soft clay subgrades)

• Landfill containment walls (with HDPE geogrids)

• Green reinforced slopes (vegetation + geogrid synergy)

(Complies with ISO 10318, ASTM D5262, and AASHTO M288 standards)
