Geotextile-Gemembrane Composites
1.
General:
Geotextiles can be laminated on one or both sides of a geomembrane for a number of purposes. The geotextiles provide increased resistance to puncture, tear propagation, and friction related to sliding, as well as providing tensile strength in and of themselves. Quite often, however, the geotextiles are of the nonwoven, needle-punched variety and are of relatively heavy weight. In such cases the geotextile component acts as a drainage media, since its in-plane transmissivity feature can conduct water, leachate or gases away from direct contact with the geomembrane
2.Specifications:
1) One layer of geo-textile fabric, and one layer of geo-membrane.
The weight of geo-textile fabric ranges from 100g/sqm to 600g/sqm.
The thickness of geo-membrane ranges from 0.2mm to 1.5mm.
2) Two layers of geo-textile fabric, and one layer of geo-membrane.
The weight of geo-textile fabric ranges from 100g/sqm to 600g/sqm.
The thickness of geo-membrane ranges from 0.2mm to 1.5mm.
3. Advantages:
Good flexibility, with the same isolation, drainage, reinforcement, protective functions of geo-textile fabric, and also being impermeable.
4. Usage:
Widely used in dam, traffic tunnel, road, airport, drainage, housing, environmental protection and many other fields for waterproof, reinforcement etc.
