Geogrids Mesh

Biaxially stretched plastic geogrids have great tensile strength in both longitudinal and transverse directions. This structure can provide a more effective chain system for bearing and diffusing forces in soil, suitable for large-scale permanent bearing foundation reinforcement.

Uniaxially stretched PP geogrid is made of high molecular polymer, which is plasticized and extruded into sheets, punched, heated and then stretched longitudinally. It is laid in the soil, and through the interlocking and interlocking effects between the grid mesh and the soil, an efficient stress transmission mechanism is formed, so that the local load can be quickly and effectively spread to a large area of soil. This reduces local damage stress and improves the service life of the project.

Mining Plastic Geogrid is made of polypropylene. It is produced through through several processes: extruding, punching, heating, longitudinal stretching and transverse stretching. It has a high tensile strength. After adding some percent of carbon black material, it makes the product good acid and alkali resistance, corrosion resistance and ageing resistance and durability. Mining Plastic Geogrid is widely used for Improving the bearing capacity of foundation, Preventing cracking and subsiding. It is an economic construction material which is convenient to construct, reducing cost and maintaining expense. Compared with uniaxial geogrid, PP/Plastic Biaxial Geogrid can provide longer service time, higher strength and nicer reinfrocement ability.

Applications of Geogrids Mesh

Geogrids have been greatly used for the construction of earth-sustained and earth-supported structures like mechanically stabilized earth (MSE) retaining walls, steep slopes, and further structures. Its application areas comprise.

❖1. Geogrids for pavements

Geogrids applications in pavement and roadway are made up of subgrade improvement, reinforcing the core course, sub-infrastructure, and surface courses. The outward displacement of railway ballast is apprehended and the settlement is shortened when they are reinforced with geogrids soft subgrade, the stiffer geogrids function better than flexible geogrids as the latter instantly reacts to the applied load.

❖2. Geogrids for retaining wall

Geogrids are accustomed to stabilizing the backfill in retaining walls. The stability of the earth retaining wall counts on the friction angle. Creep and stress relaxation properties influence the performance of geogrids in a retaining wall.

❖3. Geogrids for soil foundation

Both Uniaxial and Biaxial geogrids are typically used in foundation works. The main condition to attain good stability is the interlocking capacity of geogrids and aggregates.

❖4. Geogrids for slope stabilization

he geogrids reinforcement in slope prompts primarily the slope deformation and stability. The bearing capacity majorly depends on the length of the geogrids. To attain the best performance the aperture size should be closely equal to 0.2 times the width of the footing.

❖5. Geogrids for structural elements

In structural elements, the geogrids are used as further reinforcement and as shear reinforcement. To obtain good strength fibers such as polypropylene and steel are used. The geogrids reinforcement brings about high ultimate load-bearing capacity], enhanced energy absorption and reduced slippage, shear, and bond strength, lesser drying shrinkage, and shortened degradation rate.
