Product Introduction
Multi-directional plastic geogrid is a highly efficient reinforcement material in civil engineering. Compared to traditional unidirectional or bidirectional geogrids, its most significant feature lies in the evolution of its mechanical structure.
Working Principle
In simple terms, the working principle of multi-directional geogrids (mainly tri-directional geogrids) is like weaving a **"360-degree all-around tight-fitting suit"** into the foundation.
It can be understood from three key points:
1. The "triangular effect" in structure
This is its biggest difference from ordinary geogrids.
More stable: Ordinary geogrids have square holes, which easily deform into parallelograms; multi-directional geogrids have triangular holes. According to geometric principles, triangles are the most stable and will not deform under stress.
Isotropic: Regardless of the direction of pressure, the three sides of the triangle can evenly withstand the force, with no weak points.
2. The "locking effect" (interlocking) of the stone: The geogrid itself does not bear weight; it relies on **"clustering":**
When you lay crushed stone on top of the geogrid and compact it, the stones will get stuck in the triangular holes.
The geogrid acts like countless tiny pliers, locking each stone firmly in place.
In this way, the originally loose stones become a hard "composite board," preventing them from shifting when a vehicle drives over them.
3. The "Divergent Effect" of Pressure
It transforms **"point pressure" into "area pressure"**:
Imagine wearing high heels and stepping into mud; you'll sink in. But if you place a large, hard wooden plank under your feet, you won't.
The multi-directional grille acts as this "plank." When a heavy vehicle presses on a single point, the pressure radiates outwards along the triangular ribs, significantly reducing the load on that particular point in the foundation.

Application Case
Application
1. Highways and Urban Roads
New Road Construction: Paved into the roadbed to prevent deep ruts from being created by heavy trucks.
Existing Road Reconstruction: Paved over the existing road surface and then covered with asphalt to prevent underlying cracks from spreading upwards.
2. Heavy-Duty Transportation Sites
Logistics Parks: Places where containers and large trucks are frequently parked.
Airports and Ports: Runways, aprons, container terminals—places with extremely high load-bearing capacity requirements.
3. Railways and Rail Transit
High-Speed Rail/Conventional Rail: Paved into the ballast layer under the rails to prevent the gravel from being scattered and reduce the frequency of rail maintenance.
Subways: Foundation reinforcement around stations.
4. Soft Soil Foundations
Muddy Ground, Swamps, Tidal Flats: When building houses or constructing roads on these "muddy" areas, a layer of grating is laid first. It acts like a skeleton to support the entire project and prevent foundation subsidence.
