  • Needle-punched non-woven Geotextiles are made from polypropylene fibres that are tangled together by a needle-punching process. The fibres may be made in continuous or short lengths (the short length fibres are called staple fibres) and achieve their strength by interlocking. Needle-punched non-woven Geotextiles have excellent water flow rates and are used for filtration of soil fines for drainage applications including trench drains, as a wrapping for perforated pipe, for erosion protection, and combined with three-dimensional structures to create prefabricated drains. They are also commonly used with geomembranes to provide a protective cushion. Needle-punched non-woven primary functions: filtration; separation; protection; drainage. Secondary functions: reinforcement.

Performance

  • PP Non Woven Geotextiles are designed in such a way to perform the following 4 criteria
  • Retention, Permeability, Clogging and Survivability
  • Retention : This is a very important criteria. It prevents excessive migration of soil
  • Permeability : Permeable enough so that liquids are allowed to flow without disturbing the flow rate
  • Clogging : Enough pore openings to help filteration even if a few pores are clogged
  • Survivability: Must show strength, chemical resistance, environmental resistance and maintain sustainability throughout the usage life


Geotextile Functions :

  • Separation function: Separation of two layers of soil with different soil physical properties, such as road gravel from soft sub-base materials.
  • Filteration function: Retaining fine particles when water passes from a fine-grained to a coarse grained layer, such as when water flows from a sandy soil into a Geotextile wrapped gravel drain.
  • Drainage function: To drain liquid or gas in the plane of the fabric which results in draining or venting of the soil, such as a gas vent layer in a landfill cap.
  • Reinforcement function: Improving the load bearing capacity of a soil structure, such as a high strength Geotextiles to reinforce a retaining wall.
  • Protection function: Mechanical protection of geomembranes against perforation and abrasion, such as a liner protective layer when only gravel fills are available.
