Geogrid and geotextile are both widely used geosynthetic materials, but they are designed to solve different engineering problems.
Geogrid has an open grid structure and provides reinforcement, confinement, and stabilization through mechanical interaction with soil, aggregate, or other fill materials. It is commonly used in roads, soft soil foundations, slopes, and retaining structures.
Geotextile is mainly used for separation, filtration, drainage, and protection. It can be placed between different soil or aggregate layers to reduce material mixing while allowing water to pass through.
In short, geogrid mainly addresses reinforcement and structural stability, while geotextile mainly addresses separation and filtration.
Therefore, the two products should not simply be compared by asking wh...
