Specifications

High strength, anti-corrosion, tearing resistant and bursting resistant.

High strength polyester industrial yarns are adopted and, after treated with PVC laminating process, the geomembranes are abtained. These membranes prevent the permeation of water and change the defects of the current geomembranes with low strength and poor water resistance. As a result, they are widely used in such projects as the railroad foundation, dyke protective slopes, reservoirs, highway greenery belts, etc.

Application

Railroad foundations, tunnels, dykes, reservoirs, garbage filling fields, water-prevention and anti-permeation projects. Anti-seepage works of dyke. And application in anti-seepage works of water canal can save 80% of water.

Features

High strength, anti-corrosion, tearing resistant and bursting resistant.

Q:What is the effect of soil type on geogrid performance?: The effect of soil type on geogrid performance can vary significantly. Different soil types have varying properties such as cohesion, friction angle, permeability, and compaction characteristics, which can directly influence the interaction between the geogrid and the soil. The geogrid's effectiveness in reinforcing the soil, providing stability, and distributing loads can be affected by factors like soil type, particle size distribution, moisture content, and density. Ultimately, the geogrid's performance may be enhanced or compromised depending on the specific soil type it is installed in.

Q:Is there a big difference between horizontal permeability and vertical permeability coefficient: For example, geotextile, geomembrane, soft water pipes, etc.. According to the direction of the water flow, the coefficient of permeability of the geotextile is measured

Q:Are geogrids suitable for use in ground reinforcement for wind farms?: Yes, geogrids are suitable for use in ground reinforcement for wind farms. Geogrids provide excellent load-bearing capacity, soil stabilization, and erosion control, making them ideal for reinforcing the ground in areas with high wind speeds. They distribute loads effectively, reduce soil movement, and enhance the overall stability of the ground, ensuring the proper functioning and longevity of wind farm infrastructure.

Q:How do geogrids prevent cracking in asphalt pavements?: Geogrids prevent cracking in asphalt pavements by distributing and reinforcing the load from traffic and reducing tensile stresses within the pavement. Additionally, they enhance the overall structural integrity and stability of the pavement by minimizing differential settlements and controlling reflective cracking.

Q:Are geogrids suitable for use in soil reinforcement for pipeline river crossings?: Yes, geogrids are suitable for use in soil reinforcement for pipeline river crossings. Geogrids are engineered materials that provide stability and strength to soil structures. They can effectively reinforce the soil and prevent erosion, which is essential for maintaining the stability of pipelines in river crossings. Additionally, geogrids have high tensile strength and are resistant to environmental conditions, making them a reliable choice for such applications.

Q:Who knows the laying method of geogrid?: When the f. nail is fixed, the grid overlapping distance is as follows: the longitudinal joint overlap distance is not less than 15cm, and the transverse overlapping distance is not less than 5cm. The longitudinal lap shall be placed on the top of the rear plate in accordance with the direction of asphalt paving.G. fixed nails can not be nailed on the glass, can not be directly hit the glass with a hammer. If the nail is found to be broken or loose after fixing, it will need to be fixed.H. to prevent the construction vehicle tires will be fiberglass grille and stick together. And the asphalt concrete paver wheel slip phenomenon, should be in the surface of the oil layer of stone, stone chip amount of 3m3/1000m2-5m3/1000m2.

Q:What kind of products are the high strength and high strength micro - pile geocell? Introduce some specific details. Thank you: The double direction high strength micro pile lattice chamber has a unique welding point strengthening edge structure. The high strength is achieved by strengthening the sheet between the edges.

Q:What is the recommended geogrid junction spacing for specific applications?: The recommended geogrid junction spacing for specific applications varies depending on factors such as soil conditions, load requirements, and project specifications. It is best to consult with a geotechnical engineer or refer to industry guidelines and standards to determine the appropriate geogrid junction spacing for a specific application.

Q:What kind of projects are used to detect the geogrid: Appearance, physical properties (including: Determination of mass per unit area, amplitude measurement, mesh size measurement); mechanical properties (including: tape tensile test, joint / joint wide strip tensile test, solder joints)

Q:How do geogrids improve the performance of flexible pavements?: Geogrids improve the performance of flexible pavements by enhancing their stability, reducing rutting and cracking, and increasing their overall lifespan. They act as a reinforcement layer within the pavement structure, distributing and transferring the load more efficiently. This helps to minimize pavement deformations and increase resistance to fatigue and shear stresses. Geogrids also restrain the lateral movement of aggregate particles, preventing their displacement and improving the pavement's resistance to lateral spreading and cracking.
