The Difference Between A Biaxial Geogrid and A Unidirectional Geogrid

What is a unidirectional geogrid and a biaxial geogrid

Geogrid is one of the main geosynthetic materials. Compared with other geosynthetic materials, it has unique properties and effects. Commonly used as reinforcement of reinforced soil structure or reinforcement of composite materials.

Bidirectional geogrid is a bidirectional structure, with bidirectional stretching function, a mesh structure, square mesh geogrid.

The unidirectional  geogrid is a unidirectional structure with a unidirectional stretching function, one direction stretching molding, and the mesh is thin and rectangular.

Advantages of biaxial geogrid：

Bidirectional geogrid is a bidirectional structure with bidirectional tensile function, the raw material is mostly polypropylene, the material has a large tensile strength and modulus in the longitudinal and transverse. This structure provides a more complete interlocking system in the soil and is therefore used to strengthen the foundation of large-area sexual bearing.

Advantages of the unidirectional geogrid：

A uniaxial geogrid is a unidirectional structure with a unidirectional stretching function that provides stability in only one direction, primarily longitudinal. Unidirectional polyethylene geogrid: This material is characterized by a fairly high tensile strength and tensile modulus in the tensile direction, which provides the ideal interlocking system for the soil, and the tensile rate is low. It is an ideal reinforcement material at present.

The difference in the application of unidirectional geogrids and biaxial geogrids：

The main use of unidirectional plastic geogrid is to strengthen weak foundations; Reinforced asphalt or cement pavement; Reinforcement of road embankments and retaining walls; Strengthening river seawalls; Dispose of the landfill. 

Special application of unidirectional plastic geogrids: low temperature resistance. 

Biaxial  plastic geogrid are suitable for all kinds of embankment and subgrade reinforcement, slope protection, tunnel wall reinforcement, large airports, parking lots, dock freight yards and other long-term load foundation reinforcement
