Our geotextile can be made of polypropylene (PP) or polyester(PET) . The weight is available from 100g/m2 to 1200g/m2 and the width from 1m to 6m, two kinds of processing technical to select: needle punched and thermally bonded, long fiber or short fiber. All kinds of colors are available.
It is widely known as earthwork material and industry fabric, used in the areas of railway, highway, water conservancy, dam, tunnel, subway, environment protection and so on.
We can supply different specifications as customers’ request.
The function of Geotextiles
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.
