Description 

Plastic geogrid is mainly manufactured from polypropylene or high density polyethylene, which are all UV stabilized, chemical and biological resistance. The plastic geogrid is mainly used in the construction of roadways, highways, railways, slopes for ground stabilization and subgrade reinforcement. The plastic geogrid is extruded into sheet and then punched into regular mesh pattern and finally stretched. According to the stretched direction, it can be divided into uniaxial plastic geogrid and biaxial plastic geogrid.

Uniaxial plastic geogrid

Uniaxial plastic geogrid, made of high molecular polymer, is extruded into sheet and then punched into regular mesh pattern and finally stretched in the transverse direction. This production can ensure the structural integrity of the geogrid. The main materials of the uniaxial plastic geogrid are high density polyethylene and polypropylene, which are highly oriented and resists elongation when subjected to heavy loads for long period of time.

Features

• Can be used in the wet or dry environments.
• UV stabilized.
• Used with variety of materials, including soil and concrete.
• Resistance to the low temperature. It can be used in the minus 45 degree to 50 degree.
• Resistance to the long term chemical or biological degradation.
• High stability and bearing capacity to increase service life.
• High tensile loads in the transverse direction.
• Prevent the material loss caused by the roadbed distortion and crack.
• Lightweight for quick installation and low construction cost.

Applications

• Due to the features of resistance to the low temperature, the uniaxial plastic geogrid is ideal for the frozen soil in the northern areas.
• It can be used in the road, highway, railway, slop construction to improve the load capacity and extend the service life of the road.
• Because of the resistance to the chemical and biological and the interlocking with the infill materials, the uniaxial plastic geogrid can be used in the retaining wall and dam construction for stability and durability
