Case Study

  • Location: Philippines
  • Product:20KN-20KN PP Biaxial Plastic Geogrid
  • Application: Large Parking Lot

Issue

A Philippine customer has a large parking lot that needs to purchase geogrids for foundation reinforcement. At present, customers are a little confused about PP Uniaxial Geogrid and PP Biaxial Geogrid, and it is unclear which one to choose.

After communicating and explaining with customers, sending product introductions, photos, construction pictures and cases projects, customers finally learned that uniaxially stretched plastic geogrids have extremely high tensile strength and tensile modulus, while biaxially stretched plastic geogrids have extremely high tensile strength and tensile modulus. In addition to its high tensile strength in both longitudinal and transverse directions, the grid can provide effective bearing capacity in soft soil foundations and can make it an integral interlocking system. Finally customer choose to use PP Biaxial Geogrid.

The difference between the application of PP Uniaxial Geogrid and  PP Biaxial Geogrid.

  1. Conceptual difference. PP Uniaxial plastic geogrid is formed by extruding high molecular polymer into thin plate, punching regular mesh, and then stretching longitudinally. This process can make the polymer into an oriented linear state and form an oblong network-like monolithic structure with uniform distribution and high node strength, which has relatively high tensile strength and tensile modulus.  PP Biaxial plastic geogrid is made of high molecular polymer through the process of extrusion, plate forming and punching, and then stretched vertically and horizontally. The Biaxial plastic geogrid has great tensile strength in both longitudinal and transverse directions. This structure can also provide a more effective force bearing and diffusion ideal interlocking system in the soil, which is suitable for large areas. Permanent bearing foundation.
  2. Application difference. Uniaxial plastic geogrids are mainly used to reinforce weak foundations; reinforce asphalt or cement pavements; reinforce embankment slopes and retaining walls; reinforce rivers and seawalls; and treat landfills. Special application of Uniaxial plastic geogrid: low temperature resistance. Biaxial plastic geogrid is suitable for various dams and roadbed reinforcement, slope protection, cave wall reinforcement, large airports, parking lots, docks and other long-term load-bearing foundation reinforcements. The main functions of the Biaxial plastic geogrid are to increase the bearing capacity of the roadbed and prolong the service life of the roadbed; prevent the road from collapsing or cracks, and keep the ground beautiful and tidy; it is convenient for construction, saves time and effort, shortens the construction period, and reduces maintenance costs; Cracks occur in culverts; strengthen soil slopes to prevent soil erosion; reduce the thickness of the cushion to save costs; support the stability of the grass-planted mesh pads on the slopes, and green the environment; it can replace the metal mesh and be used for false roof meshes in coal mines.

Summary

Plastic biaxial Geogrid is a major geosynthetic material, which has unique properties and efficacy compared with other geosynthetics. Bidirectional geogrids are often used as reinforcement for reinforced soil structures or as reinforcement for composite materials. Geogrids are divided into four categories: plastic geogrids, steel-plastic geogrids, fiberglass geogrids and fiberglass polyester geogrids.

The Biaxial Geogrid is made of high molecular polymer through extrusion, plate forming and punching process, and then stretched vertically and horizontally. The material has great tensile strength in both longitudinal and transverse directions. This structure can also provide a more effective force bearing and diffusion ideal interlocking system in the soil, which is suitable for large-scale permanent bearing. Foundation reinforcement.

Since the macromolecules of the polymer in the manufacture of the  plastic Geogrid will be rearranged and oriented during the heating and extension process, the bonding force between the molecular chains is strengthened, and the purpose of improving its strength is achieved. Its elongation is only 10% to 15% of the original sheet. If anti-aging materials such as carbon black are added to the geogrid, it can make it have better durability such as acid resistance, alkali resistance, corrosion resistance and aging resistance.
