Ngesikhathi senqubo yokwakha, izimo zezulu kufanele zihlangabezane nezidingo zokwakhiwa kwe-geomembrane ehlanganisiwe. Naka le mininingwane ngesikhathi sokwakha. Uma uhlangabezana nemimoya enamandla noma izinsuku zemvula ezingaphezu kwezinga lesi-4, ngokuvamile ukwakhiwa akufanele kwenziwe.
Ngokuvamile, izinga lokushisa kufanele libe phakathi kwama-degree Celsius angu-50 no-40. Esimweni sezulu esinomoya, umoya uzothinta ukwakhiwa. Emazingeni okushisa aphansi, i-geomembrane kufanele icindezelwe futhi icindezelwe ngokuqinile ngamasaka esihlabathi. Emazingeni okushisa aphezulu, i-membrane kufanele ikhululeke. Ukubeka i-HDPE Ngaphambi kwe-geomembrane, kufanele kunikezwe isitifiketi sokwamukelwa esifanele sobunjiniyela bezokwakha. Ngokuvamile emakhoneni nasezigabeni ezikhubazekile, ukuhamba phezu kobuso be-membrane, amathuluzi okuhambisa, njll. kufanele kuncishiswe, futhi ubude bomthungo kufanele buncishiswe.
Kudingeka ukugwema ukuguga kwe-geomembrane ngangokunokwenzeka, futhi imibimbi yokwenziwa kufanele igwenywe. Noma iyiphi into engabangela umonakalo ku-geomembrane ehlanganisiwe akufanele ibekwe ku-membrane noma ithwalwe ku-membrane ngaphandle kokushisela ngangokunokwenzeka. Uma izinga lokushisa liphansi, kufanele liqiniswe futhi libekwe ngethafa ngangokunokwenzeka. I-subgrade isekelwe emhlabathini wangempela kanye nezimo ze-geological ngesikhathi sokwakha. Kungale ndlela kuphela lapho singonga khona izindleko futhi sithuthukise ukusebenza kahle kokwakha.
Izici eziyinhloko ezithinta ukuguga kwe-geomembrane ehlanganisiwe yimisebe ye-ultraviolet yelanga kanye namandla okukhanya kwe-ultraviolet yelanga. Kunzima ukugwema ukuthintana nokukhanya, ukushisa kanye nomoya-mpilo ngesikhathi sokugcina, ukuthutha, ukwakha kanye nokusetshenziswa. Isetshenziswa ezimweni ezahlukahlukene ze-geological kanye nezesimo sezulu esibi. Kuyinto enhle yokulwa nokugqwala engamelana nokugqwala kwama-asidi aqinile, ama-alkali kanye namafutha, futhi inekhono elinamandla lokuzivumelanisa nokulingana kwe-geological.
Nakuba ezinye izinto eziphakeme neziphansi zivinjelwe ukuthi zifakwe ohlwini phansi. Futhi qiniseka ukuthi i-membrane kanye ne-geomembrane ehlanganisiwe kanye ne-membrane kanye nobuso besisekelo kufanele kubekwe phansi futhi kuxhunywe kahle. Ifanele futhi amatshe ephrojekthi okulondolozwa kwamanzi noma ezinye izimpahla ezibukhali. Lapho ugcwalisa ungqimba oluvikelayo kanye nobuso obuvikelayo be-masonry, kufanele futhi unake ukuphatha ngokucophelela. Nge-HDPE I-membrane engangeni manzi engu-10 cm Ingqimba evikelayo ebanzi yomhlabathi kumele ihlungwe futhi ikhululwe kancane. Kufanele kuqashelwe ukuthi indawo yokubeka ifilimu ngesikhathi esisodwa inzima kakhulu ukuba ibe yimbi.
Umsebenzi oyinhloko we-composite geomembrane ukuthemba ukuthi lezi zinto zingavundiswa kangcono zibe izinto zokusetshenziswa. Kunesiqinisekiso esanele sokwenza wonke umsebenzi kangcono futhi kuqinisekiswe ukuthi usetshenziswa ngendlela efanele. Ukwakhiwa okuningi kobunjiniyela kanye nokulahlwa kukadoti akugcini nje ngokungcwaba nokumboza. Ukumba amachibi kudinga ukusetshenziswa. Abakhiqizi be-geomembrane bangavimbela ukungena futhi bavimbele ukuvuza kanye nokuvezwa.
