    Product characteristics
    1、 High unidirectional tensile strength, good creep resistance, and stable chemical properties;
    2、 Large friction coefficient with gravel.
    Scope of application
    1、 It is mainly used in retaining walls, bridge abutments, and steep slope projects;
    2, retaining wall and bridge abutment belong to the force structure body, and bear all the external loads: active soil pressure, dynamic load on the upper part of the structure, temperature stress, etc., the reinforced material is under the action of large tension for a long time, as well as the repeated action of dynamic load, the molecular structure of the material produces fatigue, the performance of its attenuation, accelerate the aging of the grille. To avoid the structure due to the creep of the reinforced material and produce large deformation, high-density polyethylene (HDPE) as the raw material of the unidirectional geogrid.
    Construction method
    When used for road base and road surface, the construction method is the same as two-way geogrid.
    When used for reinforced soil retaining wall, the construction method is as follows:

    1. Set up the foundation and construct it according to the designed wall system. When the prefabricated reinforced concrete panel is elected, it is generally 12-15cm thick and supported on the prefabricated concrete foundation. Its width is not more than 30㎝, thickness is not less than 20㎝, and depth is not less than 60㎝ to prevent the influence of frozen foundation.

    2. Leveling the wall foundation, excavating, and leveling according to the design requirements. Soft soil needs to be compacted or refilled, compacted to the required density and should be slightly beyond the range of the wall surface.

    3. Laying of reinforcement material, the main strength direction of the reinforcement material should be perpendicular to the wall surface, and fixed with pins.

    4. The wall is filled with soil by machinery, and the distance between the wheels and the reinforcement material should be kept at least 15 cm. The thickness of one layer of soil after compaction is about 20-15 cm.

    5. When the wall is constructed, the wall surface should be wrapped with geotextile fabric to prevent leakage of earth filling.

What Are the Environmental Benefits of Using Unidirectional Stretch Plastic Geogrid?
Unidirectional stretch plastic geogrid, a specialized geosynthetic material, offers a multitude of environmental benefits when utilized in civil engineering and construction projects. As society increasingly prioritizes sustainability and eco-conscious practices, understanding the environmental advantages of this innovative material becomes paramount. 
1. Reduced Environmental Footprint:One of the primary environmental benefits of using unidirectional stretch plastic geogrid lies in its ability to reduce the overall environmental footprint of construction projects. Traditional methods of soil stabilization and reinforcement often involve extensive excavation, transportation of heavy materials, and significant disturbance to natural landscapes. In contrast, geogrids require minimal excavation and can be installed with fewer heavy machinery and resources. 
2. Preservation of Natural Resources:Unidirectional stretch plastic geogrid minimizes the depletion of natural resources by offering a more efficient alternative to traditional construction materials. For instance, in soil retaining structures, geogrids reduce the need for conventional materials such as concrete, steel, and aggregates, which are often sourced through resource-intensive mining and quarrying processes. 
3. Erosion Control and Soil Conservation:Erosion poses a significant threat to soil quality and ecosystem health, leading to loss of arable land, sedimentation of water bodies, and degradation of natural habitats. Unidirectional stretch plastic geogrid plays a crucial role in erosion control by stabilizing soil surfaces and preventing soil displacement caused by wind, water, or gravitational forces. When incorporated into erosion control measures such as retaining walls, embankments, and slope stabilization systems, geogrids help maintain soil integrity, reduce sediment runoff, and protect fragile ecosystems from degradation.
4. Improved Water Management:Effective water management is essential for mitigating the adverse impacts of floods, droughts, and water scarcity on both natural and human-made environments. Unidirectional stretch plastic geogrid contributes to improved water management by enhancing the infiltration and drainage characteristics of soil profiles. By reinforcing soil structures and promoting uniform water distribution, geogrids help prevent waterlogging, control runoff, and facilitate groundwater recharge. 
5. Long-Term Durability and Performance:The long-term durability and performance of unidirectional stretch plastic geogrid further contribute to its environmental benefits. Unlike traditional materials that may degrade over time due to corrosion, weathering, or biological decay, geogrids are engineered to withstand harsh environmental conditions and maintain their structural integrity for extended periods. 
6. Promotion of Sustainable Land Use Practices:By facilitating the implementation of sustainable land use practices, unidirectional stretch plastic geogrid supports ecosystem resilience and biodiversity conservation. Whether applied in agricultural terracing, reclamation of degraded land, or restoration of natural habitats, geogrids provide a versatile solution for addressing land management challenges while minimizing ecological disturbance. Moreover, the integration of geogrids with revegetation efforts promotes the establishment of native plant species, enhances soil fertility, and creates habitat corridors for wildlife, contributing to ecosystem restoration and conservation goals.
7. Energy Efficiency and Carbon Reduction:Reducing energy consumption and carbon emissions is paramount in combating climate change and achieving global sustainability objectives. Unidirectional stretch plastic geogrid contributes to energy efficiency by streamlining construction processes, reducing transportation distances, and minimizing the use of heavy machinery.
