1.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.
2.Properties:
High strength,anti-aging,Acid and Basic Resistance,abrasion resistance,flexibility,and easy for construction.
3.Specification:
100g/m2 - 800g/m2
4.Size of Package:
width 4m-6m,length 50m-100m (or at request).
5.Geotextile joints to connect
General Geotextile joints to connect there is overlap, welding and oversew three ways.
Note:If geotextile joints to connect on the flat ground, overlap width30cm.
If geotextile joints to connect not on the flat ground, overlap width50cm.
