projets d\u2019infrastructure pour contr\u00f4ler la migration des fluides et prot\u00e9ger les sols et les ressources en eau. Le choix du mat\u00e9riau et du produit appropri\u00e9s \u2014 qu\u2019il s\u2019agisse d\u2019installations de stockage de d\u00e9chets, de sites miniers, d\u2019aquaculture ou de syst\u00e8mes d\u2019irrigation \u2014 permet de r\u00e9duire les risques \u00e0 long terme ainsi que les co\u00fbts li\u00e9s au cycle de vie. Ce guide compare les diff\u00e9rents types de g\u00e9omembranes couramment employ\u00e9s, souligne les facteurs \u00e0 prendre en compte lors de la s\u00e9lection et de l\u2019installation, et pr\u00e9sente les gammes de produits Megaplast adapt\u00e9es aux applications les plus fr\u00e9quentes.  \n<h2>R\u00f4le des g\u00e9omembranes<\/h2>\nLes g\u00e9omembranes font office de rev\u00eatements ou de couvertures \u00e0 faible perm\u00e9abilit\u00e9 qui pr\u00e9viennent la contamination, retiennent les fluides et s\u00e9parent les mat\u00e9riaux. Parmi leurs avantages, on peut citer le confinement des lixiviats ou des liquides issus de proc\u00e9d\u00e9s, la r\u00e9duction des infiltrations et la protection des sols sous-jacents. Les facteurs d\u00e9terminant leur performance sont le polym\u00e8re de base (PEHD ou PEBDL), la formulation (stabilisants contre les UV et les agents chimiques), l&rsquo;\u00e9paisseur des membranes, la qualit\u00e9 des soudures et les pratiques de mise en \u0153uvre.  \n<h2>Types de g\u00e9omembranes courants et crit\u00e8res de choix<\/h2>\n<h3>G\u00e9omembranes en PEHD \u2014 haute r\u00e9sistance et stabilit\u00e9<\/h3>\nLes g\u00e9omembranes en poly\u00e9thyl\u00e8ne haute densit\u00e9 (PEHD) sont couramment prescrites lorsque la r\u00e9sistance \u00e0 la traction, la r\u00e9sistance au poin\u00e7onnement et la stabilit\u00e9 chimique constituent des priorit\u00e9s.
