2. High tensile strength.
3. Reduce the chance of geotextiles embedded in the mesh core and maintain long-term stable drainage.
4. Withstand high pressure load for a long time (can withstand compressive load of about 3000Ka).
5. Resistant to corrosion, acid and alkali, and long service life.
6. Convenient construction, shortening the construction period and reducing costs.

Strengthening soil: Composite drainage networks can closely integrate with soil, enhance the tensile and shear strength of soil, improve the stability and bearing capacity of soil, and be used for slope and slope reinforcement to slow down soil erosion and landslide occurrence.
Plant growth: Composite drainage networks can serve as the bottom layer of vegetation coverage systems, providing good drainage and ventilation conditions, promoting plant growth and root development, and are used for greening, landscape, and ecological engineering.
