Une g\u00e9omembrane lisse est un rev\u00eatement synth\u00e9tique imperm\u00e9able haute performance, fabriqu\u00e9 en poly\u00e9thyl\u00e8ne haute densit\u00e9 (PEHD), en poly\u00e9thyl\u00e8ne basse densit\u00e9 lin\u00e9aire (PEBDL) ou en polychlorure de vinyle (PVC). Caract\u00e9ris\u00e9e par sa surface plane et non textur\u00e9e, elle constitue une excellente barri\u00e8re contre la migration des liquides et des gaz. Largement utilis\u00e9es pour le confinement, le rev\u00eatement et l'\u00e9tanch\u00e9it\u00e9, les g\u00e9omembranes lisses sont appr\u00e9ci\u00e9es pour leur faible perm\u00e9abilit\u00e9, leur flexibilit\u00e9 et leur durabilit\u00e9 \u00e0 long terme, aussi bien en milieu expos\u00e9 qu'en milieu enterr\u00e9.<\/p>","protected":false},"excerpt":{"rendered":"\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
