Composite Geotextiles are multi-layered combinations of geosynthetic materials. Geocomposites are usually made from UV resistant woven fabrics and a non-woven fabric or reinforced filament to optimize performance and/or minimise cost.
Geocomposites are regularly used in dewatering applications, to remove silt and control pollution from dredging operations, to intercept and remove leachates from landfill sites, and to transmit gases or water beneath pond liners.
Geotextile-polymer core composites, such as strip drains, allow very large quantities of liquid to flow inside a drainage core while a filter fabric prevents soil particles clogging the core.
Laminated geotextiles provide increased resistance to puncture, tear propagation, and friction related to sliding, as well as good tensile strength.
Applications for Composite Geotextiles:
- Slope and wall reinforcement
- Strip and panel drains for construction and civil engineering projects
- Cushioning to protect geomembrane liners
- Reinforced silt barriers to contain silt runoff into streams
- Floating silt curtains to control pollution during dredging operations in low current and wave situations
- Geotextile dewatering bags for desludging wastewater ponds
- Geotubes for dredging operations where both high tensile strength and filtration properties are required
- Prefabricated vertical drains for dewatering applications.
Benefits of Composite Geotextiles:
- Enhanced functions
- Increased interface friction angles
- Increased speed of installation
- Superior separation, cushioning, reinforcement and drainage
- Floating silt curtains effectively control pollution during dredging operations
