Composite Geogrid is a high-performance geosynthetics composed of a variety of materials, mainly used for foundation reinforcement, soil stabilization and structural enhancement in civil engineering.
Soil conditions and properties are important considerations in the design of infrastructure construction projects. Poor soil properties can either make construction impossible or lead to performance failures that can be costly. Regardless of the project type proper soil reinforcement and/or stabilization are typically needed to ensure sound structural stability and longevity of the infrastructure being built.
Geogrid and Geocells are the most effective solutions to stabilize and reinforce soils for various base applications, and soil walls and slopes. They work to do two critical things:
1) improve the mechanical properties of soil by reducing stress-strain behavior; and
2) improve the mechanical behavior of granular material by minimizing movement and allowing for effective load distribution.
Common projects where soil reinforcement and stabilization products are needed:

Composite method 1: geogrid are Self Adhesive Fiberglass Geogrid or self adhesive polyester geogrid, geotextile are polyester filament geotextile or short silk geotextiles. geotextile bonded to the Geogrid with a pressure sensitive adhesive.
Composite geogrid the new material that can prevent the reflection cracking,water damage and improving loading capacity in the project of road construction and renovation.It has the properties of high temperature rut resistance and anti-fatigue cracking, therefore prolong the life time of pavement.
Composite method 2: composite geogrid are manufactured by heat bonding a polypropylene biaxial geogrid to a needle punched nonwoven geotextile. They combine reinforcement of problematic soils with the additional functions of separation and filtration. Its design allows the biaxial geogrid to create a strong mechanical interlock with the aggregate and for the nonwoven geotextile to filter and separate the soil. Various tensile strengths are available..
