There are many specific application examples for the combination of geogrid and non-woven fabric. Here are some typical real-world deployment scenarios:
1. Road and traffic route construction
Objective: To improve the load-bearing capacity and avoid subsidence.
Example: When building access roads on soft ground, the combined product is installed between the subsoil and the base course.
Use & Benefits:
-
The geogrid stabilises the base course.
-
The non-woven fabric prevents soil and gravel from mixing.
2. Railway embankment construction
Goal: Long-term stability and drainage.
Example: Below track bedding, the combined product is used to distribute the loads evenly and to drain water.
Use & Benefits:
-
Reduction of track deformation.
-
Extension of maintenance intervals.
3. Supporting structures and slope protection
Goal: Reinforcement of steep slopes or retaining walls.
Example: In combination with reinforced earth, the geogrid nonwoven product is installed in layers.
Use & Benefits:
-
Increased shear strength.
-
Erosion protection through the non-woven fabric.
4. Landfill construction
Objective: Protection of seals and separation of materials.
Example: The combination product is installed between the waterproofing film and the drainage layer.
Use & Benefits:
-
Protection of the geomembrane from mechanical damage.
-
Ensuring the filter function.
5. Agricultural roads and forest roads
The goal: drivability even on soft ground.
Example: The combined product is laid under gravel roads in forest areas.
Use & Benefits:
-
Prevention of rutting.
-
Longer service life of the paths.
