Geotextile is a permeable fabric made from synthetic fibers, such as polyester or polypropylene, and is widely used in civil engineering, construction, and environmental projects.

Geotextile is a permeable fabric made from synthetic fibers, such as polyester or polypropylene, and is widely used in civil engineering, construction, and environmental projects. Its primary functions include separation, filtration, drainage, reinforcement, and erosion control.

1.Separation:
● Prevents the mixing of different soil layers (e.g., subsoil and aggregate).
● Maintains the integrity and functionality of each layer.
● Commonly used in road construction to separate the subgrade from the base material.

2.Filtration:
● Allows water to pass through while retaining soil particles.
● Prevents soil erosion and clogging of drainage systems.
● Used in drainage applications, such as behind retaining walls or in French drains.

3.Drainage:
● Facilitates the flow of water along its plane.
● Reduces water pressure and prevents waterlogging.
● Applied in subsurface drainage systems, landfills, and sports fields.

4.Reinforcement:
● Adds tensile strength to soil, improving stability.
● Used in combination with other materials (e.g., geogrids) for soil reinforcement.
● Common in slope stabilization and embankment construction.
5.Erosion Control:
● Protects soil surfaces from water and wind erosion.
● Used in coastal areas, riverbanks, and slopes
