Reinforced geotextile

This reinforced geotextile is complexed of high strength filament and non-woven fabrics. The fabrics arrange straightly, which gives full play to its carrying capacity. Non-woven fabric is arranged below down, wind up, tight together. Therefore, it own both filtering trait and the strong strength of organic woven.

character:1) aging resistance

         2) good durability

         3) high friction coefficient

         4) anti-corrosive of chemicals

2.  function

1) Reinforced, isolation, filtering, draining, protection.

2) be a kind of great geotechnical engineering material.

3) widely used in dam constructions of river, lake, sea, storage reservoir

4) widely used in ash disposal dam of electric power plant, mine, airport, good storage yard, railway, high way, tunnel, municipal public works, environment protection projects.

5)main functions are inverted filter and isolation.
