Geogrid is a major geosynthetic material with unique properties and efficacy compared to other geosynthetics. It is commonly used as a reinforcement for reinforced soil structures or as a reinforcement for composite materials, for example. geogrids are made from polypropylene, PVC, and other polymers by thermoplastic or molding.

What to look for when constructing a geogrid
Geogrids provide back filtration, drainage, separation, reinforcement, impermeability, and protection. Statistics from manufacturers show that the material is currently used in waterworks levees, earth canal embankments, and inland port terminals. In recent years, more and more attention has been paid to the construction of flood protection projects and the number of construction projects has increased, leading to its use in embankment projects becoming more and more common.
Especially in urban embankment projects, the slope of the river embankment always tends to be steeper to reduce the area of the embankment project and increase valuable land resources. For embankment projects using earth and stone fill, when the fill material cannot meet the stability requirements of the slope, the use of geogrid can not only solve the stability requirements of the slope but also reduce the uneven settlement of the embankment body, which has good engineering benefits.
Firstly, geogrids have high tensile strength, ranging from 25-110kn/m depending on the type of product.
Secondly, the stress elongation is small and has good lateral limit stability enhancement to the structure.
Thirdly, it has high physical and chemical stability with good resistance to aging, soil burial, and corrosion.
Fourthly, high friction coefficient, the mesh structure is fully integrated with the soil and stone structure, which enhances the stable performance of the structure. Fifthly, it has a strong resistance to environmental stress, small deformation during stress enhancement, and a small temperature deformation coefficient in the range of -20°C to 120°C.
Finally, geogrids are generally 4-6 meters wide, light in weight, easy to install, efficient, and economical.
Firstly, when storing and laying, prolonged exposure to sunlight should be avoided, otherwise, performance degradation is likely to occur. When laid in the vertical direction, it should be lapped according to the construction drawings and must be firmly connected.
Secondly, the construction quality must meet the construction requirements as stipulated in the design and construction drawings. During the construction process, no wrinkling, overlapping, or twisting should occur, and the tension of the geogrid needs to be maintained so that it is evenly stressed, and if it is manually stretched, it must be placed close to the ground, the force must be evenly applied and the surface must be flat, in addition, nails need to be used to hold the geogrid in place to avoid displacement.
