product performance
Geotextiles have the functions of isolation, filtration, drainage, protection, stabilization, and reinforcement. They can adapt to uneven bases, can resist damage from external forces during construction, have little creep, and can maintain their original functions under long-term loads.
The main purpose
Widely used in embankment projects of rivers, lakes, reservoirs, power plant ash dams, mine tailings dams, airports, railway foundations, roads, tunnels, municipal, environmental protection and other engineering fields. It has the characteristics of corrosion resistance, aging resistance and high strength.
main specifications
