When geogrid/geomembranes are combined with woven or nonwoven geotextile for specific applicaion like drainage, erosion control,bank embankment,etc. Then they are designed as Geocomposites.
A typical example is bentonite geocomposite.
It consists bentonite filled pores when this geotextile come in contact with water the bentonite causes the pores to swell thereby forming water tight sheets.
Glass fibers are knitted on to the non woven geotextiles to enable better use in highway application.
Application areas of composite geogrid
Composite Geogrid has shown wide application value in multiple engineering fields due to its high strength, corrosion resistance, and deformation resistance.
Road and rail engineering
Roadbed reinforcement: used for soft foundation treatment of highways and railways to reduce settlement.
Retaining wall and slope protection: improve structural stability through reinforcement, such as reinforced earth retaining wall.
Water conservancy project
1. Roadbed reinforcement and soft foundation treatment
It is widely used in the reinforcement of soft soil foundations of highways and railways, and reduces settlement and differential settlement by enhancing the tensile properties of the soil. For example, in road widening projects, it can effectively solve the connection problem between the new and old roadbeds and prevent cracks.
2. Pavement crack resistance and life extension
Laying composite geogrids in asphalt concrete pavements can disperse stress concentration, significantly reduce reflective cracks, cracking and other diseases, and extend the service life of the pavement.
3. Slope protection and retaining wall reinforcement
It is used for highway and railway slopes and reinforced soil retaining walls to prevent landslides and collapses by enhancing soil friction and integrity.

Manufacturing process and performance characteristics
Production process
Thermoplastic molding: forming a grid structure through high-temperature molding or ultrasonic welding, such as the rib welding process of steel-plastic grid.
Woven composite: weaving fiber materials (such as glass fiber) with polymer substrates and coating them with resin to enhance durability.
Key performance
High strength: tensile strength can reach 30-200 kN/m, which is better than single material grid.
Corrosion resistance: suitable for engineering scenarios in acidic and alkaline environments or long-term exposure.
Water permeability and reinforcement: allowing water to pass through while enhancing soil stability and preventing landslides.
Construction and standards
Construction points
When laying, ensure that the base is flat and free of sharp objects, the grid direction is perpendicular to the force direction, and the overlap width is ≥20 cm. Avoid mechanical rolling and direct contact with the grid, and cover the filler before compacting.
Quality standards
Our geocomposite gegogrid complied with international certifications such as ISO 9001 and ASTM, and the product must pass CE certification.
