Geosynthetics Functions according to IGS :

Barrier:
The use of a geosynthetic material to prevent the migration of liquids or gases.

Containment:
The use of a geosynthetic material to contain soil or sediments to a specific geometry and prevent its loss. The contained fill takes the shape of the inflated at-rest geometry of the geosynthetic container.

Drainage (a.k.a. transmission):
The use of a geosynthetic material to collect and transport fluids.

Filtration: The use of a geosynthetic material to allow passage of fluids from a soil while preventing the uncontrolled passage of soil particles.

Protection: The use of a geosynthetic material as a localised stress reduction layer to prevent or reduce damage to a given surface or layer.

Reinforcement: The use of the tensile properties of a geosynthetic material to resist stresses or contain deformations in geotechnical structures.

Separation: The use of a geosynthetic material between two dissimilar geotechnical materials to prevent intermixing.
