Application  

membrane protection (under the membrane and/or above the membrane) eg in ‘station d’épuration’, - SNW 62


Membrane protection under oil and petrol tanks - heavy SNW


In coastal(marine) projects - heavy SNW


separate 2 different layers of aggregate
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
