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:Are geogrids resistant to biological fouling?: Yes, geogrids are generally resistant to biological fouling. Geogrids are made from materials that are not easily degradable, such as high-density polyethylene (HDPE) or polypropylene (PP), which makes them less susceptible to colonization by organisms and reduces the likelihood of biological fouling. Additionally, geogrids often have a smooth surface that makes it difficult for biofilms or other organic matter to adhere to the grid. However, it is important to note that while geogrids are resistant to biological fouling, they are not completely immune, and regular inspection and maintenance may be required to prevent any potential buildup of organic matter.

Q:Can geogrids be used in subgrade improvement?: Yes, geogrids can be used in subgrade improvement. Geogrids are commonly used to reinforce weak or unstable soil in subgrade applications. They provide additional strength and stability to the soil, allowing for better load distribution and reducing settlement.

Q:How do geogrids improve the load-bearing capacity of foundations?: Geogrids improve the load-bearing capacity of foundations by providing reinforcement and stability to the soil. These geosynthetic materials are placed within the soil layers and their interlocking geometry creates a more rigid and compact structure. This helps distribute the load evenly across a wider area, reducing the risk of settlement and increasing the overall strength of the foundation.

Q:Can geogrids be used in soil stabilization for erosion control?: Yes, geogrids can be used in soil stabilization for erosion control. Geogrids are commonly used to reinforce and stabilize soil, preventing erosion by providing strength and stability to the soil structure. They can be effective in controlling erosion on slopes, retaining walls, and other areas prone to soil movement or erosion.

Q:What are the typical dimensions and sizes of geogrids?: Geogrids typically come in various dimensions and sizes depending on their intended applications. They can range in width from 1 meter to 6 meters and have lengths that can extend up to 100 meters or even more. The thickness of geogrids can vary between 1.5 mm to 3 mm. However, it's important to note that the specific dimensions and sizes of geogrids can vary among manufacturers and depend on the specific project requirements.

Q:Are geogrids resistant to high temperatures?: Yes, geogrids are generally resistant to high temperatures. They are designed to withstand extreme temperature conditions and maintain their structural integrity.

Q:GDZ150 type one-way steel plastic welding geogrid D in the construction of the roadbed is horizontal paving also vertical spread?: The direction of the pulling force is consistent with the direction of the road extension

Q:Fiberglass grille price?: Fiberglass geogrid 50KN, 2 yuan per squareFiberglass geogrid 80KN, 3.5 yuan per squareFiberglass geogrid 100KN, 4.5 yuan per squareFiberglass geogrid 30KN, 1.7 yuan per squareFiberglass geogrid 40KN, 1.9 yuan per square

Q:Can geogrids be used in ground improvement techniques?: Yes, geogrids can be used in ground improvement techniques. Geogrids are commonly employed to reinforce and stabilize weak soils, enhance load-bearing capacity, and control soil erosion. They are effective in various ground improvement applications such as retaining walls, slope stabilization, and road construction. Geogrids provide increased tensile strength and distribute loads, resulting in improved stability and performance of the ground.

Q:Can geogrids be used in reinforcement of pavement overlays?: Yes, geogrids can be used in the reinforcement of pavement overlays. Geogrids are commonly used as a reinforcement material in pavement construction to enhance the strength and durability of the pavement structure. They are placed between layers of pavement materials to distribute loads and reduce cracking, rutting, and other forms of pavement distress. Geogrids help to improve the overall performance and lifespan of pavement overlays.
