compound Geomembrane

1. Produced excellent constructions function 2. Mass per square meter: 400g-1000g. 3. Width3m-6m, thickness0.2-0.8mm.

1. Sorts:

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.

2. Advantages:

Good flexibility, with the same isolation, drainage, reinforcement, protective functions of geo-textile fabric, and also being impermeable.

 3. Usage:

Widely used in dam, traffic tunnel, road, airport, drainage, housing, environmental protection and many other fields for waterproof, reinforcement etc.
