Geo composite
Geocomposites are engineered geosynthetic materials formed by combining two or more geosynthetic products—such as geotextiles, geogrids, geomembranes, or drainage cores—into a single integrated system.
By combining the strengths of multiple materials, geocomposites deliver enhanced filtration, drainage, separation, reinforcement, and protection in one product, reducing installation time and improving overall project efficiency.
Geocomposites : Structure & Performance
Common geocomposite configurations include:
- Geotextile + Geonet (Drainage composites)
- Geotextile + Geomembrane (Protection and filtration)
- Geogrid + Geotextile (Reinforcement and separation)
- Geonet + Geomembrane + Geotextile (Landfill and containment systems)
- Performance Characteristics
- High in-plane drainage capacity
- Excellent filtration and soil retention
- Enhanced tensile and puncture resistance
- Long service life and chemical resistance
Geocomposites are widely used in:
- Landfill leachate collection systems
- Sub-surface drainage and groundwater control
- Tunnel and retaining wall drainage
- Road and railway drainage layers
- Protection of geomembranes in reservoirs and canals
Purpose
The primary purpose of geocomposites is to combine multiple engineering functions into a single solution, providing drainage, filtration, protection, and reinforcement while minimizing material layers, labor costs, and installation complexity.
