Drainage channel - NW 12


separate 2 different layers of aggregate - NW 12, NW 16, NW 20 or NW 25
The separation application is the most common and mostly used application for geotextiles. Depending of the :
-ground conditions
-type of project (unpaved road, rural road, motorway, rail road, etc…..)
-consultancy engineer
