matériau associé

CONT: Géomembrane composée: Produit manufacturé par superposition et assemblage de plusieurs composants dont au moins une géomembrane. Les composants autres que la géomembrane sont dénommés matériaux associés; ils ne sont pas séparables de la géomembrane sans altération de celle-ci.

OBS: Association with Geotextiles and Geomembranes. Except in a few locations where they are in contact with coarse granular materials such as gravel, nets used for drainage are never put in direct contact with soil. Fine soil particles would rapidly penetrate net openings and hamper flow of liquids or gases. In most cases nets used for drainage are in contact with structural elements (concrete, sheet piles, lagging), geotextiles, or geomembranes. Nets, geotextiles and geomembranes can be supplied independently and installed successively. Composites comprising nets, geotextiles and/or geomembranes are also available or can be custom fabricated.
