Using geogrid and geotextile for soft foundation reinforcement to ensure runway foundation stability.

Materials: 600g polyester filament geotextile (separation layer)

Function: Separates the runway crushed stone cushion from the underlying soft silt soil, preventing the silt from rising and mixing with the crushed stone, significantly improving the runway foundation bearing capacity, ensuring long-term smoothness under heavy aircraft takeoff and landing loads, with no uneven settlement damage.
