Drainage Function

The major function of draining is to evacuate water or other liquids towards the structure’s outlets.


Very porous, draining geosynthetics:

  • Convey heavy flows throughout their thickness
  • Drain soil

Advantages of the use of the Drainage range

  • Economy of granular draining materials that are difficult to implement
  • Gain on the cover of the structure
  • Facility and low cost implementation
  • Continuity of draining even in case of deformation of the slope
