Specifications of Geogrid:
Warp-knitting Polyester Geogrid adopts industrial high strength, high modulus and low shrinkage twisting polyester fiber as raw material. With warp-knitted directional structure, there is no bend statement among warp and weft yarns of the fabric. The cross points of the geogrid are bundled and banded together by high-strength polyester fiber. So they form solid binding points. After coating with high-quality oil or water-soluble PVC, its physical and chemical property is greatly optimized.ams and dikes, and mountain slope 2) Can prevent land soil from water and rain erosion before grass covering grows 3) Can bear sourcing of high water space and high-speed water after grass covering grows 4) It can reduce cost of construction by width margin and the cost is only 1/7 concrete,1/8 stone 5) It adopts macromolecule material and anti-UV rays stability, and its chemical character is very stable, and there is no pollution to environment 6) Easy construction after surface of land is smooth 7) A kind of three dimensional structure new-type geosynthetical materials suitable for protecting water and land soil 8) Can effectively prevent water and land soil from flowing away, increase green land and improve living environment Operation: 1) Can use bamboo pole or wood stick pass the whole roll net mat during construction, then pull net mat along slope, use wooden nail or plastic nail to fix four circle of net mat, distance between nails is 750px, one square meter has 10 nails 2) Length of nail from land surface is usually 375px, add nails on loose land, length of nail on up slope is longer than on down slope when construction on high slope 3) Pay attention to keep netting mat smoothl
Applications of Geogrid:
Make reinforce treatment for various kinds of soft soil foundation to evenly distribute load stress and reduce uneven settlement, not easy to generate static electricity, and flammability property good in the coal mine. It is easy to wash coal.
Used in highway, railway, port, airport and municipal project. Support in the recovery working face of coal mine and roadway in the coal mine.

Geogrid Show:
- Q:What is the profit margin of the production of Geogrid
- If the product is supplied in accordance with the specifications required by the contractor
- Q:Can geogrids be used in slope stabilization for railway embankments?
- Yes, geogrids can be used in slope stabilization for railway embankments. Geogrids are commonly used in civil engineering projects to reinforce soil and provide stability. They can be installed in the slope to enhance its strength and prevent erosion, thereby ensuring the stability and longevity of railway embankments.
- Q:What is the difference between Geogrid TGSG and GSL?
- GSL is the code for the two-way stretch geogrid in the standard JT/T480-2002 of the Ministry of Communications
- Q:Are there any specific requirements for geogrid installation in road construction?
- Yes, there are specific requirements for geogrid installation in road construction. These requirements include proper site preparation, ensuring the geogrid is laid flat and taut, adequate overlap and anchoring, and proper compaction of the surrounding soil. Additionally, the geogrid should be installed according to the manufacturer's guidelines and in compliance with relevant industry standards and specifications.
- Q:Are geogrids effective in reducing pavement rutting?
- Yes, geogrids are effective in reducing pavement rutting. They provide reinforcement to the pavement structure, distributing loads more evenly and improving its overall stability. By reducing the excessive movement of the underlying soil, geogrids help mitigate rutting and extend the lifespan of the pavement.
- Q:How to restore the plastic geogrid after being destroyed?
- 3 when laying geosynthetics, the direction of high strength should be placed in the main stress direction of the embankment.4 geosynthetic materials should be paved after the design requirements of the back section, and timely coverage with sand.
- Q:How to connect two-way geogrid
- Transverse 10cm overlap with plastic tape binding on the grid
- Q:Can geogrids be used in reinforcement of concrete structures?
- Yes, geogrids can be used in the reinforcement of concrete structures. Geogrids are high-strength synthetic materials that are commonly used to enhance the stability and strength of various civil engineering projects, including concrete structures. They are typically embedded within the concrete to provide additional tensile strength and prevent cracking or failure. Geogrids are particularly effective in applications where there is a need for increased load-bearing capacity, such as road and bridge construction.
- Q:What is the effect of creep on geogrid performance?
- The effect of creep on geogrid performance is that it can cause long-term deformation and reduced tensile strength over time. Creep refers to the gradual movement or deformation of a material under constant load or stress. In the case of geogrids, prolonged exposure to sustained load or stress can result in creep, leading to a loss of the geogrid's initial stiffness and load-bearing capacity. This can negatively impact its ability to provide soil reinforcement, stability, and confinement, compromising its overall performance in geotechnical applications. Therefore, creep considerations are crucial when designing and selecting geogrids for long-term projects.
- Q:What are the limitations of geogrids?
- Geogrids have a few limitations. Firstly, they are not suitable for all types of soil and terrain conditions. They are most effective in soils with good particle interlock and cohesion. Secondly, geogrids are not effective in situations where there is high water flow or erosion potential as they do not provide sufficient protection against these forces. Additionally, geogrids may have limited strength in certain applications, such as heavy load-bearing scenarios, and may require additional reinforcement. Lastly, the installation and maintenance of geogrids can be complex and costly, requiring skilled labor and regular inspections to ensure proper functioning.
