Specifications

material: PP and PET
techincal: needle punched
usage: filtration,separation,adding muacle,protection
deliver time: 2-3 weeks

Usage:

 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 theairdrome 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.
