Polyester chemical fiber Geotextile
1. Application of geotextiles:
It can be 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.
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.
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 earthbody stability.
It prevents the bank from being washed out, protects the bank and the
Bottom, prevents the water and soil from being washed away.
