**Izinyathelo Zokuzivikela**
(1) Ukwelashwa kwezindawo ezihlangana kwi-geomembrane kuyinqubo ebalulekile ekwakhiweni, kuthinta ngqo impilo yokusebenza yephrojekthi. Ukuhlolwa kwekhwalithi kubonisa ukuthi indlela yokushisisa i-welding iyindlela efanele kakhulu (ukubopha nge-glue kusetshenziswa ama-ejenti akhethekile nakho kuyindlela). Indlela yokushisisa i-welding ihlanganisa ukushisisa izindawo zokuxhumana zamashidi e-PE geomembrane kuze kube yilapho zincibilika, bese zihlanganiswa zibe yiyunithi eyodwa, eyintelekile ngokufakwa kwengcindezi.
(2) Ama-geomembrane kufanele abekwe ngendlela efanayo. Kumele kugcinwe umkhawulo othile we-PE membrane (onganamathiselwanga ungqimba lwe-PET) emaphethelweni omabili ashidi ngalinye. Ngesikhathi sokufakwa, ukulungiswa kweyunithi ngayinye ye-geomembrane kufanele kulungiswe ngokucophelela ukuze kube lula ukuhlanganiswa okulandelayo kwamayunithi aseduze.
(3) Uma sezigotshwe, amashidi e-geomembrane kufanele acindezelwe ngezikhwama zesihlabathi ukuze kungabikho ukuhamba komoya. Imiphetho nezindawo zokuhlanganisa kufanele zigcinwe zingenawo uthuli, umswakama, nothuli, nezinye izinto ezingcolisa.
(4) Ngaphambi koku-weld, imiphetho ye-PE eyodwa yama-sheet amabili aseduze endaweni yokuhlanganisa kumele ilungiswe ngokucophelela ukuze kuqinisekiswe ububanzi obufanele bokugqagqana; izindawo ezigoqene kumele zibe ncamashi futhi zingabi namibotshana.
(5) Imisebenzi yokushisela kufanele yenziwe ochwepheshe abanolwazi besebenzisa imishini ekhethekile yokushisela. Izilungiselelo zokushisa kanye nesivinini sokushisela kufanele zilungiswe ngokucophelela (ukubopha okunamathelayo kungasetshenziswa njengenye indlela).
(6) Iminyaka yesipiliyoni esisebenzayo ibonise ukuthi ubukhulu be-geomembrane akufanele bube ngaphansi kuka-0.25 mm; amashidi amancane kakhulu angaba namaluzipho futhi alimale kalula ngesikhathi sokwakhiwa, ngaleyo ndlela athinte ukusebenza kwawo okuvimbela ukuvuza. Ngesikhathi kufakwa i-geomembrane, ukunakwa okukhethekile kufanele kunikezwe ukuqinisekisa ukuthi amashidi awabekiwe ngokuqinile kakhulu, ukuthi akukho imibotshana noma imigxumo, nokuthi zonke izixhumanisi ziboshwe ngokuqinile. Ukwakhiwa kufanele kulandele ngokuqinile imininingwane yezobuchwepheshe, kugcinwe ukulawula ikhwalithi okuqinile kuzo zonke izigaba ezinhlanu ezibalulekile: ukulungiselela, ukubeka, ukuxhuma, ukuhlola, nokugcwalisa.
