Geomembrane ndi chinthu chofunikira kwambiri cha geosynthetic chomwe chimagwiritsidwa ntchito poletsa kulowetsedwa kwamadzi kapena mpweya ndikupereka chotchinga chakuthupi. Nthawi zambiri amapangidwa ndi filimu yapulasitiki, monga polyethylene yapamwamba kwambiri (HDPE), polyethylene yotsika kwambiri (LDPE), polyethylene (LLDPE), polyvinyl chloride (PVC), ethylene vinyl acetate (EVA) kapena ethylene vinyl. Acetate modified asphalt (ECB), etc. Nthawi zina amagwiritsidwa ntchito limodzi ndi nsalu zopanda nsalu kapena mitundu ina ya ma geotextiles kuti apititse patsogolo kukhazikika kwake ndi chitetezo pakuyika.
Ma geomembranes ali ndi ntchito zosiyanasiyana m'magawo osiyanasiyana, kuphatikiza koma osachepera izi:
1. Kuteteza chilengedwe:
Malo otayiramo zinyalala: kupewa kutayikira ndi kuwononga madzi apansi ndi nthaka.
Zinyalala zowopsa komanso kutaya zinyalala zolimba: kuletsa kutayikira kwa zinthu zovulaza m'malo osungira ndi opangira mankhwala.
Migodi yosiyidwa ndi malo osungiramo tailings: kuteteza mchere wapoizoni ndi madzi oipa kuti asalowe m'chilengedwe.
2. Kusunga madzi ndi kusamalira madzi:
Malo osungiramo madzi, madamu, ndi ngalande: kuchepetsa kutayika kwa madzi olowera m'madzi ndikuwongolera kugwiritsa ntchito bwino kwa madzi.
Nyanja zopangira, maiwe osambira, ndi malo osungira madzi: sungani kuchuluka kwa madzi, kuchepetsa kutuluka kwa nthunzi ndi kutuluka.
Dongosolo la ulimi wothirira: kupewa kutayika kwa madzi panthawi yamayendedwe.
3. Zomangamanga ndi zomangamanga:
Tunnel ndi zipinda zapansi: kupewa kulowa pansi pamadzi.
Ntchito zauinjiniya wapansi panthaka ndi zapansi panthaka: Perekani zotchinga zosalowa madzi.
Kutsekereza madzi padenga ndi pansi: kuteteza chinyezi kulowa mnyumbayo.
4. Makampani amafuta ndi mankhwala:
Matanki osungira mafuta ndi malo osungiramo mankhwala: kupewa kutayikira komanso kupewa kuwononga chilengedwe.
5. Ulimi ndi Usodzi:
Maiwe a Aquaculture: amasunga madzi abwino komanso kupewa kutaya kwa michere.
Farmland ndi wowonjezera kutentha: amagwira ntchito ngati chotchinga madzi kuwongolera kagawidwe ka madzi ndi zakudya.
6. Migodi:
Tanki yotulutsa mulu, thanki yosungunula, thanki ya sedimentation: pewani kutayikira kwa mankhwala ndi kuteteza chilengedwe.
Kusankhidwa ndi kugwiritsa ntchito ma geomembranes kudzatsimikiziridwa potengera momwe angagwiritsire ntchito komanso zofunikira zachilengedwe, monga mtundu wazinthu, makulidwe, kukula, ndi kukana mankhwala. Zinthu monga magwiridwe antchito, kulimba, ndi mtengo.
