Separation
The use of a geotextile is to prevent the intermixing of dissimiar soil layers.

Geotextile – Specification & Technical Data
Non-woven geotextile fabric is made from 100% needle punched polypropylene for high filtration and penetration applications. It has durable life in gabion works in harsh environments, where require extra strength, high UV resistance and high rot prevention.

Application
It can used with woven or welded gabions for channel lining reinforcement, erosion control and flood protection.
Drainage
The use of a geotextile layer is to collect and transport fluids within its own thickness.
Filtration
Allow fluid passage (commonly water) while prevent the uncontrolled soil particles passage.
Protection
As a stress reduction layer to prevent or reduce damage to an adjacent surface or layer.
Reinforcement
The use of the tensile properties of geotextile is to resist stresses structures.
Erosion control
The use of geotextile is to prevent loss of soil particles from water erosion.
