There are several different types of geosynthetics, including:
1. Geotextiles - permeable fabrics used for filtering, stabilization, and separation.
2. Geogrids - high-strength materials used for reinforcing soil and retaining walls.
3. Geomembranes - impermeable barriers used for lining landfills, ponds, and other containment areas.
4. Geocells - three-dimensional cellular structures used for erosion control, stabilization, and reinforcement.
5. Geonets - drainage materials used for layer drainage and filtration in roadways and retaining walls.
6. Geopipes - corrugated plastic pipes used for drainage and leachate collection.
7. Geocomposites - layered materials composed of two or more geosynthetics used for various functions such as filtration, erosion control, or drainage.
