Application Range

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, soilstone dam, breakwater, airport, backfill soil of retaining wall, slope protection, etc 

in which distributes the earth stress, prevents the sidedisplacement 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.
