China wholesale high tensile strength needle punched non woven geotextile
High quality non woven needle-punched geotextile  is made of polypropylene/polyester staple fibers on cross-laying equipment and needle punched equipment. It owns the advantages of acid and alkali resistance, erosion resistance, aging resistance, large strength, stable size, good filtrability etc.

1) Weight / Mass: 100gsm - 1500gsm  

2) width: Within 8 m  

3) longth: 50-100m/roll or as per request

4) Material: polypropylene/polyester

5) Color: Black , white , grey

6) Certification: CE/ISO9001  CE  

7) Manufacturing method: Non woven
Features:

1.High strength: due to the plastic fiber, it can keep sufficient strength and elongation in the wet state.
2.Corrosion resistance: it can in different ph value of soil and water corrosion for long.
3.Good permeability: have a gap between the fibre, therefore has the good porous.
4.Good antimicrobial property: do not damaged by microbes and insects.
5.Construction is convenient: because the material is qualitative light, soft, so delivery, laying, construction is convenient.

Applications:
Major functions: Separation, filtration, drainage, reinforcement, protection, and liquid barrier
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.
Quality Control:

We have established a national-standard laboratory for in-house quality control and built a strict quality control system in all aspects from raw materials testing and production processes to final product quality testing.

Not only is stringent internal quality control carried out at OBOR, but regular testing and analyzing of our product performance is implemented by authoritative testing organizations in Europe and the United States.
