Lokhu kuhlola kuhilela ukufaka i-voltage ku-liner nokuhlonza izindawo lapho ugesi udlula khona ngokukhubazeka, okuvumela abasebenzi bokulungisa ukuthi bavale izimbobo ezitholiwe ngaphambi kokuba i-liner imbozwe ngomhlabathi noma imfucuza, ngaleyo ndlela kuvinjelwe ukuvuza kwesikhathi esizayo. Inhlanganisela yezinqubo zokufaka ezinakekelayo, izendlalelo zokuvikela, nokutholwa okuphelele koku vuza kunikeza imigqa eminingi yokuzivikela ekuvuzeleni, iqinisekisa ukuthi uhlelo lwe-geomembrane lusebenza njengoba luklanyelwe kuyo yonke impilo yalo yokusebenza ehlosiwe.

Ukuvimbela ukuvuza kwezinzwane ezindongeni eziqondile kuyinselelo ekhethekile evela lapho kuhlangana khona i-geomembrane liner nomhlabathi wesisekelo noma into yesakhiwo esisekelweni somthambeka, lapho i-liner isuka endaweni ethambekile iye kokuvundile. Indawo yozwane isengozini enkulu yokuvuza ngoba ihlanganisa izingcindezi ezivela esisindweni somhlabathi wokumboza emthambekeni, ibhekana nokuhlukana kokuzinza phakathi kwengxenye ethambekile nengxenye yesisekelo, futhi kunzima ukuyicindezela kahle ngesikhathi sokufakwa, konke lokhu kungadala izindlela zokuhamba koketshezi. Ukuze kuncishiswe ukuvuza kwezinzwane, abaklami ngokuvamile bacacisa ama-anchor noma imisele eyisihluthulelo esisekelweni somthambeka egxilisa i-geomembrane esisekelweni esizinzile, kuhlanganiswe nama-bentonite seal noma ama-grout curtain avimbela ukugeleza okukhethekayo eduze kwendawo yokuhlangana kwe-liner nomhlabathi. Ukufakwa kwama-toe anchors kudinga ukunakwa okucophelelayo kwemininingwane, okuhlanganisa ukumba kahle komsele we-anchor, ukugcwaliswa kabusha ngomhlabathi ocindezelweyo ongavumeli amanzi, nokuqinisekisa ukuthi i-geomembrane ayilinyazwa yizinto zokugcwalisela noma imishini yokucindezela ngesikhathi sokufaka i-anchor. Ithimba lokusekela lobuchwepheshe le-Geofantex lihlinzeka ngemihlahlandlela eningiliziwe yokufaka yemininingwane yezinzwane, okuhlanganisa izincomo zobukhulu bomsele we-anchor, ukucaciswa kokugcwalisela, nezinqubo zokuhlola ikhwalithi eziqinisekisa ubuqotho balokhu kuhlangana okubalulekile. Emaphrojekthini okwandisa indawo yokulahla imfucuza eqondile, lapho ama-liner amasha ehlangana nezinhlelo ezikhona zokuqukatha, umkhawulo wezinzwane uba nzima nakakhulu ngoba kufanele ubhekane nokunyakaza okungase kwehluke phakathi kwezingxenye ezindala nezintsha kuyilapho kugcina umgoqo oqhubekayo. Ukusetshenziswa kwama-bentonite water stops noma ama-geomembrane boots enziwe ngaphambilini ezindaweni zokungena kwamapayipi nasezixhumanisweni zesakhiwo kuqinisa kakhulu ukwethembeka kwendawo yezinzwane, kudala uphawu olunezingqimba eziningi oluvimbela ukuvuza ngisho nangaphansi kwengcindezi enkulu yamanzi. Ngokuhlanganisa izimiso zokuklama eziqinile nezinqubo zokufaka ezinokucophelela, onjiniyela bangakwazi ukuqeda ukuvuza kwezinzwane njengomthombo obalulekile wokwehluleka kokuqukatha, bevikela kokubili imvelo kanye nokutshalwa kwezimali kwephrojekthi.

Ukulawula Ikhwalithi Yokwakha kanye Nokuqinisekiswa Kwekhwalithi kumelela izinsika ezimbili ezihambisanayo zokuphathwa kwephrojekthi yanamuhla ye-geomembrane, lapho i-CQC ihlanganisa imisebenzi eyenziwa umfaki noma umkhiqizi ukuze kuqinisekiswe ukuthi izinto zokwakha nobuchule bokwenza kuhlangabezana nokucaciswa, kanti i-CQA ibandakanya ukugadwa okuzimele nokuqinisekiswa yinhlangano yesithathu. Uhlelo olusebenzayo lwe-CQC luhlanganisa ukuhlolwa kwezinto ezifikayo, ukuhlolwa kwemithungo yokuzama, ukuhlolwa kwemithungo yokukhiqiza, kanye nokubhalwa okusemthethweni kwayo yonke imingcele yokushisela, imisebenzi yokulungisa, nemiphumela yokuhlolwa, okunikeza irekhodi eliphelele elibonisa ukuthotshelwa kwezimfuneko zephrojekthi. Onjiniyela be-CQA benza ukuhlolwa okuzimele kohlelo lwe-CQC, babukele ukuhlolwa kwemithungo, benze ukuhlolwa okungahleliwe kwemithungo yasensimini, futhi baqinisekise ukuthi noma yiziphi iziphambeko noma ukungahambisani kukhonjwa, kuhlolwe, futhi kulungiswe ngaphambi kokuthi i-liner yamukelwe ukusetshenziswa. I-Geofantex ihlanganisa ukuphathwa kwekhwalithi kuzo zonke izigaba zenqubo yabo yokukhiqiza, kusukela ekuthengeni izinto zokusetshenziswa kuya ekukhishweni, ukwenziwa kwethukisi, ukupakishwa, nokuthunyelwa, lapho iqoqo ngalinye lokukhiqiza lihambisana nesitifiketi sokuhlaziya esibhala izakhi ezibalulekile futhi siqinisekisa ukuhambisana nezinga elishiwo. Ukuzimela komsebenzi we-CQA kubalulekile enanini lawo, ngoba kunikeza abanikazi bephrojekthi nezinkantolo ezilawulayo ukuzethemba kokuthi uhlelo lwe-liner lakhiwe ngokwamazinga amukelekile ngaphandle kokungqubuzana kwezintshisekelo okungase kukhubaze ukungachemi. Lapho bekhetha umkhiqizi we-geomembrane, amaqembu ephrojekthi kufanele ahlole hhayi kuphela imininingwane yobuchwepheshe yezinto zokwakha kodwa nokuqina kohlelo lokuphathwa kwekhwalithi lomkhiqizi kanye nokuzimisela kwabo ukusekela imisebenzi ye-CQC ne-CQA endaweni yokwakha.

Ukuqonda umehluko phakathi kwama-Typical Values, i-MARV, nama-Minimum Values kubalulekile ekuhumusheni amashidi edatha yomkhiqizo nasekwenzeni izinqumo ezinolwazi mayelana nokukhethwa kwezinto zokwakha zamaphrojekthi okuqukethwe. Ama-Typical Values amelela amazinga avamile noma alindelekile okusebenza asuselwa kudatha yomkhiqizo yomlando futhi avame ukusetshenziswa ezincwadini zokumaketha, kodwa awakhi isiqinisekiso sokusebenza kwanoma yiliphi ibhajethi lomkhiqizo elithile. I-MARV imelela i-Minimum Average Roll Value futhi ingumqondo wezibalo osetshenziswa ezindinganisweni eziningi zemboni, okuhlanganisa ne-Geosynthetic Research Institute's GRI-GM13 specification yama-HDPE geomembranes, lapho imelela khona inani okulindeleke ukuthi u-97.5% wayo yonke imiphumela yokuhlolwa iwele ngenhla kwalo uma kufingqwa kuyonke i-roll yezinto. Ama-Minimum Values, ngokuphambene, amelela umphumela ophansi kakhulu owamukelekile wanoma yisiphi isampula lokuhlolwa elilodwa, futhi ukuweqa leli nani kunoma yikuphi ukuhlolwa kubhekwa njengokwehluleka kwezinto ukuhambisana nencazelo. I-Geofantex ishicilela izincazelo ezisekelwe ku-MARV kuyo yonke imikhiqizo yayo yama-geomembrane, inikeza amakhasimende isiqinisekiso sokusebenza esiqinile ngokwezibalo esibonisa ukuzibophezela kwenkampani ekungaguquguqukeni kokukhiqiza nasekuhambisaneni nokugqwesa kwekhwalithi. Umehluko phakathi kwalezi zinhlobo ezintathu zamanani unemithelela ephathekayo ekuhlolweni kwekhwalithi ngesikhathi sokufakwa, njengoba imiphumela yokuhlolwa ewela phakathi kwe-MARV ne-Minimum Value ingadinga uphenyo olwengeziwe ukuze kunqunywe ukuthi ikhombisa isici esingokwendawo sezinto noma inkinga ebanzi yekhwalithi. Ngokucacisa izinto ezisekelwe ku-MARV noma kuma-Minimum Values kunokuba kusetshenziswe ama-Typical Values, onjiniyela bangasungula imibandela ecacile, ephoqelelekayo yokwamukela evikela ukusebenza kwephrojekthi futhi inikeza isisekelo sokuxazulula uma izinkinga zekhwalithi yezinto zivela ngesikhathi sokwakha. Ithimba lokuqinisekisa ikhwalithi le-Geofantex lisebenza eduze nezinhlangano ze-CQA zephrojekthi ukuze liqinisekise ukuthi konke ukuhlolwa kwenziwa ngokwezindinganiso ezaziwayo nokuthi imiphumela ihumushwa ngendlela efanele, kukhuthazwe indlela yokusebenzisana ebeka phambili ukusebenza kwesikhathi eside kwesistimu yokuqukethwe.

Ukukhetha i-geomembrane efanele yephrojekthi yokuquketha isinqumo esiyinkimbinkimbi esidinga ukuhlolwa ngokucophelela kwezinhlobo zezinto, izidingo zokusebenza eziqondene nohlelo, izindlela zokufaka, kanye nezinqubo zokuphatha ikhwalithi, konke okusebenzisanayo ukuze kunqunywe impumelelo yesikhathi eside yohlelo. Kusukela kuma-HDPE geomembrane liners anikeza ukumelana namakhemikhali okukhethekile nokuqina, kuya ezindaweni ezinokuthungwa ezithuthukisa ukuzinza kwemithambeka kanye nama-GCL anikeza ukuvaleka okuzivalayo, isigaba ngasinye somkhiqizo sinikeza izinzuzo ezihlukile okumelwe ziqondaniswe nezidingo eziyingqayizivele zesiza. I-Geofantex Geosynthetics, njengomkhiqizi ohamba phambili we-geomembrane, iletha ulwazi lweminyaka eminingi embonini, amandla okukhiqiza asesimanje, kanye nephothifoliyo ebanzi yemikhiqizo ye-geosynthetic ukusekela amaphrojekthi asukela kuma-landfill kamasipala nokusebenza kwezimayini kuya ezinhlelweni ze-biogas nezindawo zokugcina uketshezi. Ukuzibophezela kwenkampani ekhwalithini kugxilile kuzo zonke izici zokusebenza kwayo, kusukela ekukhetheni i-resin nokulawula ukukhiqiza kuya ekusekelweni kwezobuchwepheshe nosizo lwasensimini, kuqinisekiswa ukuthi amakhasimende athola nje into nje kodwa isixazululo esiphelele sokuquketha. Ngokuhlanganisa ama-geomembranes nemikhiqizo ehambisana nayo efana nama-geotextiles, ama-drainage geonets, nama-GCL, i-Geofantex inika amandla onjiniyela ukuthi baklame izinhlelo zokuquketha eziqinile, eziphindaphindayo ezibhekana nazo zombili izidingo zomgoqo oyinhloko kanye nezidingo zokuvikela ezesibili. Noma ngabe iphrojekthi ihilela iseli elisha le-landfill, ukunwetshwa kwe-mining heap leach, noma ukushintshwa kwekhava ye-biogas, ukusebenzisana nomkhiqizi oqonda umongo ophelele wohlelo kubalulekile ekuzuzeni ukusebenza kahle, ukuthotsela imithethonqubo, nokuphathwa kwezindleko eziphumelelayo zomjikelezo wempilo. Ngolwazi olunikezwe kulo mhlahlandlela, onjiniyela nabaphathi bamaphrojekthi bakuhlome kangcono ukucacisa, ukuthenga, nokufaka izinhlelo ze-geomembrane eziletha ukuquketha okuthembekile kwesikhathi eside, kuncishiswe ubungozi bemvelo futhi kwandiswe imbuyiselo yokutshalwa kwezimali.
