HDPE Uniaxial Geogrid is a type of geosynthetic material made from high-density polyethylene (HDPE), with continuous ribs or strands running predominantly in one direction.

The uniaxial orientation of the geogrid offers enhanced tensile strength in the direction of the ribs. When incorporated into construction layers, HDPE Uniaxial Geogrid effectively distributes tensile forces and increases the load-bearing capacity of the soil mass, preventing excessive deformation, rutting, and settlement.

Structure and Features:

HDPE Uniaxial geogrid is made of high molecular polymer after extruded and laminated and punched into regular mesh before longitudinal stretching. This process makes high molecule in direct line state in oblong oval net structure with uniform distribution and high node intensity. This structure has rather high tensile strength and stretch modulus, especially our products of this kind have superior world class tensile strength and stretch modulus with extensibility between 2% and 5%The soil offers ideal force carrying and diffusing chain system. It has large tensile strength (>150Mpa), and is suitable for different kinds of soil reinforcement material.

Its main applications are as follows:

The applications of HDPE Uniaxial Geogrid include reinforcement of road and railway foundations in various construction projects:
1. Enhance roadbed and effectively diffuse its load to improve its stability and bearing capacity and increase service life;
2. Can bear more alternate load;
3. Prevent roadbed distortion and crack caused by the loss of roadbed materials;
4. Increase the self-supporting property of fill behind retaining wall, decrease the earth pressure of retaining wall, save cost, increase service life and reduce maintenance
expense;
5. Combine anchor sprouting concrete construction method to give side slope maintenance, which not only saves investment by 30%-50% but also reduces erection time by one time or
above.
6. To increase geogrid in the roadbed and surface of highways can reduce flexure, track and put off the flawing appearance by 3-9 folds and reduce the thickness of structural
layer by 36%
7. It is applicable to any kind of soil, not necessary to draw material from other place, saving time and labor;
8. Simple and rapid construction will greatly reduce construction cost.
