*Net holes are easy for net blockage, since net structure formed by indefinite fider has variable and motility.
*It has high permeation and can keep good permeation under the pressure of earthwork.
*It has corrosion resistance, uses chemical fiber such as polypropylene or Dacronas raw material, has acid and alkali resistance, hasn't corrosion or moth eating and has oxidation resistance.
*It has convenient construction, small weight and convenient uses.
*It isolates building materials with different physical features, makes two or multiple materials with outerosion or mixing, keeps overall structure and functions of material and makes load bearing capacity of structure strengthen.
*When water flows into coarse soil layer from soil layer, it uses good gas and water permeation of knitting geotechnical geotextile, allows water flow to pass and effectively holds back soil particle, fine sand andsmall stone so as to keep stability or water onservation project.
*Itis good water guide material, and can form drainage channel in soil body and remove excessive liquid and gas from soil structutre.
*It uses knitting geotechnical cloth to strengthen tension resistance strength and deformation capacity of soil body, to strengthen stability of structure and to improve soil body quality.
*It effectively diffuses, transmits or decomposes central stress and prevents soil body damage by functioning of external force.
*Knitting geotechnical cloth matches other materials and forms nonpermeation Isolation layer.
