PP high strength woven geotextile:

 1. Specifications  

  1) Weight / Mass: 70g/m2-800g/m2 .

   2) Width: Within 8 m  (1m-8m).

   3) Length: 50m-100m/roll (as request).

   8) The biggest geotextile manufacturer/factory in China for many years . The equipment is introduced from Germany.

    9) This geotextile can be made of polypropylene (PP), or polyester (PET), Polyvinyl or synthetic fiber on needle punch machine.

  10) The mass is available from 75g/m² to 800g/m² and the width available from 1.0m-8m, monolayer or multilayer (reinforcement geotextiles), long fiber or short fiber.

 11) Color: all kinds of color are available. The annual production ability is 10 million square meters.

 12) The fabric can also be heat treated by infrared at customer's requirements. Our geotextile are UV stabilized to give protection against aging under exposure to natural ultra-violet light.

2. Introduction  

 Geotextiles are composed from synthetic polypropylene/polyester fibres through a mechanical process of needling the fabric and adding, when necessary, a thermo fused process, resulting in a uniform porous structure with excellent tensile strength and chemical deterioration. Type: 1. Wovens & knitted: use various fibre types (e.g. monofilament, multi-filament, split extruded film) in different combinations. 2. Non-wovens: staple or continuous fibres that are heat treated or needlepunched to fibres relative to each other. 

 

3. Applications   

1) Filtration

The filtration layer of the dykes, river canal, seacoast, concrete slope, retaining walls. At the same time of preventing the clay granule from passing, it allows the water and the gas pass through freely.

 

2) Separation:

The isolation of the railway dregs and the roadbed, roadbed and the soft base, surface of the airdrome and parking lot and the groundsill, different dam materials. It isolates the soil and the gravel of two kinds different granule pathway from the groundsill or other buildings.

 

3 )Adding muscle:

The highway, railway, soil-stone dam, breakwater, airport, backfill soil of retaining wall, slope protection, etc in which distributes the earth stress, prevents the side-displacement of the earth body and improves the earth body stability.

 

4 )Protection

It prevents the bank from being washed out, protects the bank and the bottom, prevents the water and soil from being washed away.
