Geomembrane ndi chinthu chofunikira kwambiri chopangidwa ndi geosynthetic chomwe chimagwiritsidwa ntchito makamaka poletsa kulowa kwa madzi kapena mpweya komanso kupereka chotchinga chakuthupi. Nthawi zambiri chimapangidwa ndi filimu ya pulasitiki, monga high-density polyethylene (HDPE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), polyvinyl chloride (PVC), ethylene vinyl acetate (EVA) kapena ethylene vinyl acetate modified asphalt (ECB), ndi zina zotero. Nthawi zina imagwiritsidwa ntchito limodzi ndi nsalu yosaluka kapena mitundu ina ya geotextiles kuti iwonjezere kukhazikika ndi chitetezo chake panthawi yoyika.
Ma geomembrane ali ndi ntchito zosiyanasiyana m'magawo osiyanasiyana, kuphatikizapo koma osati zokhazo:
1. Kuteteza chilengedwe:
Malo otayira zinyalala: letsani kutuluka kwa madzi otayira ndi kuipitsa madzi a pansi pa nthaka ndi nthaka.
Zinyalala zoopsa komanso kutaya zinyalala zolimba: kuletsa kutuluka kwa zinthu zoopsa m'malo osungira ndi otsukira.
Malo osungiramo zinthu m'migodi ndi m'mabwinja osiyidwa: amaletsa mchere woopsa ndi madzi otayira kulowa m'chilengedwe.
2. Kusamalira madzi ndi kasamalidwe ka madzi:
Madziwe, madamu, ndi ngalande: amachepetsa kutayika kwa madzi kulowa m'madzi ndikuwonjezera kugwiritsa ntchito bwino madzi.
Nyanja zopangira, maiwe osambira, ndi malo osungiramo madzi: kusunga madzi okwanira, kuchepetsa kuuma ndi kutuluka kwa madzi.
Njira yothirira yaulimi: imaletsa kutayika kwa madzi panthawi yoyendera.
3. Nyumba ndi zomangamanga:
Ma ngalande ndi zipinda zapansi: zimaletsa madzi apansi panthaka kulowa.
Mapulojekiti a uinjiniya wapansi panthaka ndi sitima yapansi panthaka: Perekani zotchinga zosalowa madzi.
Kuteteza madzi padenga ndi pansi pa nyumba: kuletsa chinyezi kulowa m'nyumbamo.
4. Makampani opanga mafuta ndi mankhwala:
Matanki osungiramo mafuta ndi malo osungiramo mankhwala: kuletsa kutuluka kwa madzi ndikupewa kuipitsa chilengedwe.
5. Ulimi ndi Usodzi:
Maiwe olima m'madzi: kusunga madzi abwino komanso kupewa kutayika kwa michere.
Malo olima ndi obiriwira: amagwira ntchito ngati chotchinga cha madzi chowongolera kufalikira kwa madzi ndi michere.
6. Migodi:
Tanki yotulutsira madzi mumtolo, thanki yosungunula madzi, thanki yosungira madzi mumtolo: letsani kutuluka kwa madzi a mankhwala ndikuteteza chilengedwe.
Kusankha ndi kugwiritsa ntchito ma geomembrane kudzatsimikiziridwa kutengera zochitika zinazake zogwiritsidwa ntchito komanso zofunikira pa chilengedwe, monga mtundu wa zinthu, makulidwe, kukula, ndi kukana mankhwala. Zinthu monga magwiridwe antchito, kulimba, ndi mtengo.
