PET Nonwoven Geotextile
1.Geotextile has good air and water permeability to let water flow through it so as to effectively control sand rock running-down.
2.It has good water permeability, it can form drainage channels inside soil mass to drain redundant liquid and air out of the soil mass. It helps to enhance the soil mass' tensile strength and non-deform-ability and structural stability so as to improve soil mass quality.
3.It can effectively make the concentrated stress diffuse, transfer or compounded, and prevent the soil mass against the destruction of outside force.It can prevent the mixture of sandstone, soil mass and concrete of upper and lower layers.
Its mesh is hard to jam by virtue of the com-pliancy and motility of the reticulation formed by indefinite form fibrous tissue. High water permeability-it can keep good water permeability even in the pressure of soil and water.
4.Corrosion resistant-it is made from polypropylene fiber or Terylene or other chemical fiber, featuring resistance to acid and alkali and oxidation, non-corroding, no worm-eaten.
Easy construction-low weight, easy operation, simple construction.
Introduction
Staple fibers needle punched geotextiles is a kind of composite geomaterial with good permeability which is punctured using composite fiber. Cloth-like product has the general width of 4-6 meters and a length of 50-100 meters.
The product has excellent permeability, acquired, durability, which can be widely used in railway, highway, movement hall, DAMS, hydraulic structures, hence hole, coastal shoal, reclamation, environmental protection and other projects. Basically have nonwoven geotextile and electricity crack membrane silk weaving geotextile.
Function
Filtration of soils in drainage applications by retaining soil particles while allowing for the free flow of water
Separation and stabilization in road and railway construction
Prevention of soil movement in erosion control measures
Cushioning and protection in many containment projects
