Product Description

Non Woven Fialment Spounbond Fabric

Our nonwoven continuous filament geotextiles are made from 100% polyester fibres, mechanically bonded by needle punching. Heat bonding can also be applied to further strengthen the geotech fabric. Nonwoven polyester continuous filament geotextiles have a high melting point and UV resistance. They provide an effective and economical solution for filtration, separation, drainage, liner protection and reinforcement applications.


1.Geotextile has good air and water permeability to let water flow through it so as to effectively control sandrock running-down.
2.Geotextile has good water transmissibility, it can form drainage channels inside soil mass to drain redundant liquid and air out of the soil mass.
3.Geotextile helps to enhance the soil mass’ tensile strength and non-deformability and structural stability so as to improve soil mass quality.


1.It can effectively make the concentrated stress diffuse, transfer or decompound, and prevent the soil mass against the destruction of outside force.
2.It can prevent the mixture of sandstone, soil mass and concrete of upper and lower layers.
3.Its mesh is hard to jam by virtue of the compliancy and motility of the reticulation formed by indefinite form fibrous tissue.
4.High water permeability-it can keep good water permeability even in the pressure of soil and water.
5.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.
6.Easy construction-low weight, easy operation, simple construction

The continuous filament structure of nonwoven geotextiles permits water to pass through while preventing soil migration. Spunbonded polyester nonwoven geotextiles are more cost effective than natural filters when used for revetment and subsoil drainage applications.

Nonwoven continuous filament geo fabrics are suitable for separating two layers of soil with different physical properties. Separating soft ground from coarse fill material reduces the amount of fill required and increases the life span of civil engineering structures such as roads and railways. They are frequently used in railway construction to separate the capping layer from the ballast layer.

Nonwoven geotech fabrics improve the drainage performance of subsoil drainage systems in roads, railways, sports fields and behind retaining walls. They are ideal for draining or venting soils, such as the gas vent layer in a landfill cap.

Liner protection
Needle free nonwoven geotextiles are ideal for protecting HDPE liners from punctures and excessive deformation. The cushioning relieves stress and minimises the chance of contained harmful liquids or landfill waste leaking.

The strength offered by nonwoven continuous fibre geotextiles can improve the load bearing capacity of a soil’s structure, such as the reinforcement of a retaining wall.
