Biaxial Geogrid

Material：polypropylene
Feature：High tensile strength
Application Field：highways, railways, airports, parking lots, and docks
Shipping Method：logistics
Product Category：Geogrid

Bidirectional plastic geogrids feature an appearance similar to a square mesh structure. They are primarily made from polypropylene and manufactured through extrusion followed by longitudinal and transverse stretching, resulting in a high-strength geotechnical material. This material exhibits significant tensile strength in both longitudinal and transverse directions and is widely used in reinforced soft soil foundation treatment.

Performance

Biaxial geogrids offer the following advantages:

1、Enhanced Foundation Bearing Capacity
By increasing the bearing capacity of roadbeds or foundations, they extend service life and effectively prevent ground collapse or crack formation.

2、Improved Pavement Stability
The mesh structure restricts aggregate displacement, resists high-temperature rutting and low-temperature shrinkage cracking, mitigates reflective cracking, disperses stress concentration, and enhances fatigue cracking resistance.

3、Shortened Construction Period
Easy and convenient installation reduces construction time and lowers maintenance costs.

4、Reduced Project Costs
Decreased required thickness of cushion layers lowers overall project expenses.

5、Adaptability to Harsh Environments
Resistance to high temperatures, low-temperature conditions, and aging makes them suitable for soft soil foundation treatment and culvert reinforcement.

Application

1、Suitable for subgrade and pavement reinforcement in various highways,railways,and airport runways.

2、Ideal for permanent load-bearing foundation enhancement in large parking lots,码头货场(dock yards),and freight terminals.

3、Used for secondary reinforcement of slopes previously reinforced with uniaxial geogrids,further strengthening the soil structure and preventing erosion.

4、Applicable for culvert reinforcement.

5、Effective in slope protection projects for railways and highways.

6、Suitable for mine and tunnel reinforcement.

7、Designed specifically for livestock and poultry fencing in agricultural applications.

8、Used in aquaculture for fish cage netting.
