Geos Filter is a polyester needle-punched nonwoven geotextile made of continuous filament fiber for drainage, filtration, separation and reinforcement in civil works such as river or tide bank protection, blind ditch and tunnel works. Through special designing and production process, Geos Filter is produced so that it can provide optimum physical and hydraulic properties suitable for public works.

• Geos Filter has higher tensile and tearing strength than other products, and also has uniform openings between filament fibers. The uniform openings provide excellent hydraulic  performances.
• Geos Filter made of 100% polyester has a good resistance to UV light, aggressive bacteria in soil, acid and alkali agents.
• Geos Filter is a geotextile filter which doesn’t make environmental contaminants, and it is stable at temperatures of – 40°C ~ 100°C.

As Geos Filter has flexible and strong structure, it can be easily seamed and installed. Geos Filter is produced in various widths from 2.1m  to  4.2m and well adapted for field work. It significantly reduces construction costs. The specific gravity of Geos Filter is 1.36 which allows an excellent underwater installation.

• Prevention from land sliding of revetment slope
• Erosion control of bank slope
• Protection of waterproof layer in disposal landfill
• Filtration of blind ditch and collecting culvert
• Protection and drainage of waterproof sheet in tunnel
• Prevention of road cracking
