Plastic geogrids can be divided into unidirectional plastic tensile geogrids, bidirectional plastic tensile geogrids, and convex node bidirectional (plastic) geogrids.

Unidirectional tensile geogrid is made of polymer extruded into thin sheets, punched with regular holes, and then longitudinally stretched. During this process, the polymer is oriented in a linear state and forms a uniformly distributed, high node strength, elongated elliptical network like overall structure. This structure has a relatively high tensile strength and modulus, providing the soil with an ideal chain system for bearing and diffusing forces. This product has a high tensile strength (>150Mpa) and is suitable for various soils, making it a widely used reinforcement material.

Main purpose:

1. Strengthening the roadbed can effectively distribute diffusion loads, improve the stability and bearing capacity of the roadbed, and extend its service life;

2. Can withstand larger alternating loads;

3. Prevent roadbed deformation and cracking caused by the loss of roadbed materials;

4. Improve the self-supporting capacity of the backfill behind the retaining wall, reduce the soil pressure on the retaining wall, save costs, extend the service life, and reduce maintenance costs;

5. Combining the anchor spraying concrete construction method for slope maintenance can not only save 30% -50% of investment, but also shorten the construction period by more than twice;

6. Adding geogrids to the roadbed and surface layer of highways can reduce deflection, minimize ruts, delay crack occurrence time by 3-9 times, and reduce structural layer thickness by up to 36%;

7. Suitable for various soils, no need to source materials from other places, saving labor and time;

8. The construction is simple and fast, which can greatly reduce the construction cost.

biaxial geogrid

Bidirectional geogrid is made of high molecular weight polymer through extrusion, plate forming, punching process, and then longitudinal and transverse stretching. This material has high tensile strength in both longitudinal and transverse directions, and this structure can also provide an ideal chain system for more effective force bearing and diffusion in soil, suitable for large-scale permanent bearing foundation reinforcement.

Product Features:

1. Increase the bearing capacity of the roadbed and extend its service life.

2. Prevent the collapse or cracking of the road (ground) surface, and maintain a beautiful and neat appearance of the ground.

3. Convenient construction, time-saving, labor-saving, shortened construction period, and reduced maintenance costs.

4. Prevent cracks from forming in culverts.

5. Strengthen the soil slope to prevent soil erosion.

6. Reduce the thickness of the cushion layer to save costs.

7. Support the stability and greening environment of the slope with grass and mesh mats.

8. Can replace metal mesh and be used for false roof mesh in coal mines.

Product Usage

Biaxially oriented plastic geogrid is suitable for various embankment and roadbed reinforcement, slope protection, tunnel wall reinforcement, permanent bearing foundation reinforcement of large airports, parking lots, dock cargo yards, etc.

Application scope:

1. Reinforcement of roadbeds for various highways, railways, and airports;

2. Ground reinforcement for permanent load-bearing structures such as large parking lots and dock cargo yards;

3. Slope protection for railways and highways, and reinforcement of culverts;

4. The secondary reinforcement of the soil slope after unidirectional tensile geogrid reinforcement, further enhancing the soil slope and preventing soil erosion;

5. Reinforcement of mines and tunnels.

Convex node bidirectional (plastic) geogrid

High tensile strength - the longitudinal and transverse tensile yield strength per meter can reach 20-150KN, which has been tested by the Product Quality Supervision and Inspection Center of the Ministry of Transport, Railway, and Water Resources.

Small deformation - the yield elongation of the convex node steel plastic geogrid is ≤ 3%; The yield elongation of convex plastic geogrid is ≤ 10%.

High node strength - This product uses a fused cast convex node connection to form a grid with longitudinal and transverse reinforcement strips. Its node strength is high, and the shear strength of welded grid nodes is ≥ 1.5MPa. The ultimate peeling force of convex node grid nodes is ≥ 300N.

Long service life - plastic is a material for protecting high-strength steel wire, and it is also a force bearing material for plastic grid. It has chemical properties of acid, alkali and salt corrosion resistance, and has anti-aging and anti-oxidation properties through scientific formulation.

Suitable for various permanent projects, with a service life of over a hundred years.

Good effect - the grid mesh casting convex node structure enhances the interlocking effect between the grid and the soil, can restrain the lateral displacement of the soil, enhance the bearing capacity of the foundation, reduce the overall settlement of the soil and improve the uneven settlement of the soil, enhance the overall performance of the foundation, and prevent surface cracking.

Cost saving - proven through several engineering examples.
