Non woven geotextile Property
1. Good acid and alkali resistance, excellent hot melting
adhesiveness, high anti-abrasion performance
2. Separation, filtration, drainage, reinforcement, protection, and
maintenance function
Non woven Geotextile Application
It widely used in railway,road,gymnasium,dike,marine
works,tunnel,tideflat,reclamation and environment protection
projects.
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.
They use include:
Water conservancy project and hydropower project
Road paving , railway , highway ...
Airport and port
River bank protection and tunnel
Environmental protection , etc
