The bidirectional plastic geogrid is made by extrusion, sheet forming, and punching processes, followed by longitudinal and transverse stretching of high molecular polymer. This material boasts significant tensile strength in both directions, offering an ideal interlocking system for force distribution and transfer within the soil, suitable for reinforcing large-area foundations. It is applicable for reinforcing embankments, roadbeds, slope protection, and wall reinforcement in large airports, parking lots, and cargo yards, among other load-bearing foundations.

Construction Method

Excavate the foundation bed, install a sand layer (not exceeding 10cm in elevation), compact it into a platform, lay the geogrid, ensuring the longitudinal axis aligns with the main load-bearing direction. The longitudinal overlap should be 15-20cm, and the transverse overlap 10cm. Secure the overlaps with plastic tape, and at intervals of 1.5-2m, fasten the laid geogrid to the ground using U-shaped nails. The geogrid should be promptly backfilled with soil material, and the number of layers laid will depend on technical requirements.

Bidirectional geogrids are used to increase the bearing capacity of roads and foundations, extending their service life.

2. Bi-directional geogrids are used to prevent road or ground collapse or cracking, maintaining the ground's aesthetic and orderly appearance.

3. Bi-directional geogrids facilitate construction, saving time, effort, and shortening project duration, as well as reducing maintenance costs.

4. Bi-directional geogrids are used to prevent cracks in culverts.

5. Bi-directional geogrids are used to reinforce soil slopes and prevent soil and water erosion.

6. Bi-directional geogrids are used to reduce the thickness of the sublayer, saving on construction costs.

7. Bi-directional geogrids are used to support the stability of the green environment for边坡植草网垫.
