TRIGRID®EX Geogrid - Soil Reinforcement
TRIGRID®EX – Advanced Soil Reinforcement Solution from Japan
1. Introduction
TRIGRID®EX is an advanced tri-axial soil reinforcement geogrid system developed and widely applied in Japan for slope stabilization, roadbed reinforcement, and reinforced soil retaining walls. With its unique structure, TRIGRID®EX provides more effective load distribution compared to traditional uni-axial or bi-axial geogrids.
2. Key Technical Features
Tri-axial structure: Distributes load effectively in multiple directions, enhancing overall soil stability.
High tensile strength: Withstands large multi-directional forces, minimizing ground deformation.
Compatible with various fill materials: Can be combined with local soils, aggregates, or recycled materials, optimizing construction costs.
Environmental durability: Made from high-quality polymers, resistant to aging, chemicals, and harsh environmental conditions.
3. Practical Applications
TRIGRID®EX has been applied in numerous projects in Japan and worldwide, including:
Reinforced soil retaining walls: Construction of vertical or steep retaining walls exceeding 20m in height.
Slope and embankment stability: Mitigates slope sliding and ground settlement.
Railway and highway construction: Improves load-bearing capacity and foundation lifespan.
Weak soil and coastal areas: Minimizes uneven settlement and enhances long-term stability.
4. Superior Advantages Compared to Traditional Solutions
| Load direction | Uni-axial or bi-axial | Tri-axial, multi-directional |
| Reinforcement efficiency | Average | High, long-term stability |
| Deformation resistance | Prone to deformation | Significantly reduced deformation |
| Long-term cost | High (frequent maintenance) | Cost-effective, extended service life |
5. Prospects for Application in Vietnam
Given Vietnam’s diverse topography—mountainous areas, weak soils, and high embankments, along with the growing demand for expressways and high-speed railways, TRIGRID®EX is highly suitable for:
Building sustainable infrastructure foundations.
Stabilizing slopes along mountain highways and expressways.
Constructing high retaining walls in urban and industrial areas.
Coastal and riverbank projects to mitigate erosion and subsidence.
6. Conclusion
TRIGRID®EX is not only an advanced construction material but also a comprehensive engineering solution for safe, sustainable, and cost-effective infrastructure development.
This proven Japanese technology holds strong potential for widespread application in Vietnam’s future infrastructure projects.
