Polyester/ Polypropylene Nonwoven geotextile fabric for highway road construction

Short fiber Needle Punched Nonwoven Geotextile Description

Short fiber Needle Punched Nonwoven Geotextile Specification

 1.Material: 100% original PP /PET staple fiber.

Short fiber Needle Punched Nonwoven Geotextile  Application

 PP nonwoven geotextile currently support many civil engineering applications incliding roads, airfields, railroads, embankments, retaining structures, reservoirs, canals, dams, bank protection, coastal engineering . Usually geotextiles are placed at the tension surface to strengthen the soil. Geotextiles are also used for sand dune armoring to protect upland coastal property from storm surge, wave action and flooding. 

Short fiber Needle Punched Nonwoven Geotextile Property

 1.Separation  Geotextiles will prevent two soil layers of different particle sizes from mixing with each other , as is illustrated the image below.

2.Drainage  Geotextiles will efficiently collect superfluous water from structures , such as rainwater or surplus water, from the soil and discharge it.

3.Filtration Geotextiles are an ideal interface for reverse filtration in the soil adjacent to the geotextile , in all soils water allowa fine particles to moved . Part of these particles will be halted at the filter interface;  some willbe halted within the filter itself while the rest will pass into the drain. The complex needlepunched structure of the geotextile enables the retention of fine particles without reducing the permeability of drain.

4.Reinforcement  Heavy geotextile can be used to reinforce earth structures by means of fill materials . THanks to their high soil fabric friction coefficient and high tensile strength, they are an ideal reinforcement solution.

5.Protection  Geotextile are an ideal protection from erosion of earth embankments by wave  action, currents or repeated drawdown. A layer of geotextile can be  placed so as prevent leaching of fine material. They can be used for rock beaching or as mattress structure.they can even easily be placed under water.
