Needle-punched nonwoven geotextiles are made from polypropylene fibres that are tangled together in a needle-punching process. The fibres may be made in continuous or short lengths and achieve their strength by interlocking.
Needle-punched nonwoven geotextiles have excellent water flow rates and are used for filtration of soil fines. Needle-punched nonwoven geotextiles have been used in drainage applications including trench drains (also known as french drains), as a wrapping for perforated pipe, for erosion protection, for the separation of a roads sub base and base course, and combined with three-dimensional structures to create prefabricated drains.
They are also commonly used with geomembranes to provide a protective cushion. Needle-punched nonwoven primary functions: filtration; separation; protection; drainage.
Nonwoven Geotextiles have a wide range of applications in civil environmental engineering and construction projects. Their uses include

*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.
Geotextiles will efficiently collect surplus water from structures, such as rainwater or surplus water, from the soil and discharge it.
Our geotextiles provide superior hydraulic flow and soil retention, which makes them well suited for filtration in subsurface drainage applications and under hard armour systems.
Geotextiles are used for paved and unpaved roads, where ground conditions have been compromised. As a separation layer, geotextiles can aid preventing the intermixing of dissimilar materials, add to the performance life of the road and reduce the overall thickness of the road section by requiring less aggregate during construction.
High strength geotextiles can be used to reinforce earth structures as the strength of the tape or filament within the fabric may be increased to suit a specific application. Thanks to their high tensile strength they are an ideal reinforcement solution.
Due to the consistent thickness and weight of our Geotextiles, they provide adequate cushioning and protection for critical lining systems.
