Video related to the real-life application of geosynthetics is attached below.

Geotextiles refers to a permeable synthetic textile material which is generally produced from polyster or polypropylene polymers. It can be used for
seperation, drainage, filtration, protection,reinforcement, erosion control.

A geotextile is a geosynthetic fabricated to be permeable and can be classified by the way they are manufactured as either woven or nonwoven

In addition, some applications of geotextile is listed below,

-Road work (Widely used in construction of the roads, it reinforces the soil by adding tensile strength)
-Railway works (geotextiles used to seperate the soil from the sub soil without impeding the groundwater circulaion)
-Drainage (Protect river banks from erosion due to currents or lapping)
