PP or PET short fiber needle punched non woven geotextile
1.Usage
Used in the area of highway, railway, dam, lam fencing for filtration, separation drainage and protection.Also can be used as carpet in the car, for the cloth liner, glove, cleaning cloth, shoes liner.etc.
2..Applications of geotextile
A.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.
B. 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.
C. 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.
D.Protection
It prevents the bank from being washed out, protects the bank and the bottom, prevents the water and soil from being washed away.
3.Specification
100GSM—800GSM
4..Property
Good flexibility, permeability, filtration, separation,adding muscle, protection and easy for construction.
5.Size of package
Width 2m-6m,length 50-100m (or at request).
6. Geotextile joints to connect
General Geotextile joints to connect there is overlap, welding and oversew three ways.
