Bidirectional Plastic Geogrid

Product Introduction 
A bidirectional stretched geotextile grid is a high-strength reinforced geosynthetic material made from polypropylene (PP) through plasticized extrusion, plate punching, longitudinal stretching, and transverse stretching. It boasts numerous advantages such as high strength, stable structure, resistance to aging, and corrosion resistance.
Technical Advantages
The company leverages its technical strengths to enhance product performance, ensuring stable and reliable quality by improving raw material characteristics, increasing the precision of mechanical equipment, and refining production processes.
We currently have an annual production capacity of over 100 million square meters for geogrids, with bidirectional stretched geogrids boasting a tensile strength of up to 50 kN/m.
Application Fields
Double-walled geogrids are primarily used for reinforcement in soft soil projects such as roads and railways, as well as for slope protection and large-scale landfill projects. They significantly enhance the load-bearing capacity of soft soil foundations, prevent surface cracking and collapse, facilitate construction, and reduce maintenance costs.

The bidirectional plastic stretched geogrid is made by extrusion, sheet forming, and punching processes, followed by longitudinal and transverse stretching using high molecular polymer. This material boasts significant tensile strength in both directions, providing an ideal连锁 system for force bearing and diffusion within the soil, suitable for reinforcing large-area foundations.

Two-way plastic geogrid

Square or rectangular polymer mesh formed by stretching, which can be uni-directional or bi-directional depending on the stretching direction during manufacturing. It is created by punching holes in polymer sheets (usually made of polypropylene or high-density polyethylene) after extrusion, and then undergoing directional stretching under heating conditions. Uni-directional stretched gratings are made by stretching along the length of the sheet only; bi-directional stretched gratings are produced by further stretching the uni-directional gratings perpendicular to their length.

Features

High strength, low creep, adaptable to various soil types, fully meets the requirements for tall retaining walls in high-grade highways.

Effectively enhances the interlocking and gripping action of reinforced bearing surfaces, significantly increases the bearing capacity of the foundation, effectively restricts lateral displacement of the soil mass, and strengthens the stability of the foundation.

Compared to traditional grates, these offer enhanced strength, load-bearing capacity, corrosion resistance, aging resistance, high friction coefficient, uniform openings, ease of installation, and a long service life.

More suitable for deep-sea operations and embankment reinforcement, it fundamentally solves the technical problems of low strength, poor corrosion resistance, and short service life caused by stone baskets made of other materials due to long-term erosion by seawater.

Application Fields

Road base reinforcement and surface reinforcement for various highways, railways, and airports.

Ground reinforcement suitable for large parking lots and wharf cargo yards.

Applicable for railway and highway slope protection.

Applicable tunnel reinforcement.

Enhanced secondary reinforcement for soil slopes after being reinforced with one-way geogrid, further fortifying the soil slope to prevent soil and water erosion.

Mine and tunnel reinforcement.
