Enhance Roads Stability And Loading Ability High Strength Polypropylene Uniaxial Plastic Geogrid
Uniaxial Plastic Geogrid Introduction
Plastic uniaxial geogrid is manufactured from plastic materials which may be high-density polypropylene or high-density polyethylene (HDPE) resins by the hot extruding process to make the resins into thin plates, the plates are punched into the regular holes for the formation of desired grids, and then the punching patterns are stretched longitudinally into the desired meshes to develop designed tensile strength.

Uniaxial Plastic Geogrid Feature
This kind of structure has high tensile strength and tensile modulus. The tensile strength reaches 100-200mpa, which is close to the level of low carbon steel. It is much better than the traditional or existing reinforced materials. In particular, this kind of product has higher early tensile strength and tensile modulus than the international level (the elongation is 2% - 5%). It provides an ideal linkage system for soil to undertake and diffuse forces. The product has high tensile strength (> 150MPa) and is suitable for all kinds of soil. It is widely used as reinforcement material at present.
Its main features are: high tensile strength, good creep performance, convenient construction and low price
Plastic Uniaxial Geogrid Applications
- For strengthening soft foundation: Geogrid can quickly improve the bearing capacity of foundation, control the development of settlement, limit the road base, effectively distribute the load to the wider subbase, so as to reduce the thickness of the base, reduce the project cost, shorten the construction period and prolong the service life.
- One way geogrid is used for reinforced asphalt or cement pavement: geogrid is laid at the bottom of asphalt or cement pavement, which can reduce rutting depth, prolong pavement fatigue life, and reduce asphalt or cement pavement thickness to save cost.
- It is used to reinforce embankment slope and retaining wall: the filling of traditional embankment, especially high embankment, often needs to be overfilled, and the edge of road shoulder is not easy to be compacted, which leads to the phenomenon of slope rain erosion, collapse and instability. At the same time, a gentle slope is needed, which covers a large area, and the retaining wall also has the same problem Reduce the floor area by half, prolong the service life and reduce the cost by 20-50%.
- It can be used to reinforce River seawall: it can be made into gabion and used together with grid to prevent the dam from collapsing due to sea water scouring. The gabion has permeability, can slow down the impact of waves, prolong the life of dike, save manpower and material resources, and shorten the construction period.
- For disposal of landfill: Geogrid combined with other geosynthetics can effectively solve the problems of uneven settlement of foundation and emission of derived gas, and improve the storage capacity of landfill site to the maximum extent.
