PET FG Geogrid Thermal Bonding Nonwoven Fabric Composite Geogrid
Reinforced Slope Subgarde
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:
- Gravel Road Construction
- General Site Base Development Work
- Railway Ballasts and Sub-ballast construction
- MSE/Retaining Wall Construction
- Embankments
- Bridge Abutments
- Protective dikes
- Underground tunnels
- Foundation engineering

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..
