Introduction
A geogrid is geosynthetic material used to reinforce soils and similar materials. The principal function of geogrids is for reinforcement. For 30 years biaxial geogrids have been utilized in pavement construction and soil stabilization projects throughout the worldwide. Geogrids are commonly used to reinforce retaining walls, as well as subbases or subsoils below roads or structures. Soils pull apart under tension. Compared to soil, geogrids are strong in tension.
Lateral spreading of base course aggregate or subbase material is the most critical and common failure in pavement structures. PP biaxial geogrid effectively reduces lateral spreading resulting in increased structural performance and pavement life.
Features and benefits
• High tensile strength in both longitudinal and transverse directions.
• Convenient to use and reduce the construction cost.
• Increase the bearing capacity of the subgrade.
• Reduce the soil erosion.
• UV stabilized.
• Resistance to the chemical and biological corrosion.
Application
1. Base reinforcement for flexible pavements.
2. Subgrade and foundation improvement: cost effective alternate to undercutting and backfilling.
3. Haul road stabilization.
4. Tunnel wall stabilization.
5. Parking areas for commercial and Industrial facilities.
6. Embankment construction over soft soils.
7. Airport runways.
8. Construction platforms on marshy soil.
9. Caps for sludge, landfill and other low bearing materials.
