Uphahla,njenge-facade yesihlanu yesakhiwo, ikakhulukazi ithwala imisebenzi yokungangeni manzi, ukuvikela ukushisa kanye nokukhanya kwelanga. Eminyakeni yamuva nje, ngesidingo esihlukile sezici zokwakha, uphahla lubhekwa njengengxenye ebalulekile yokumodela kwezakhiwo, okudingeka icatshangelwe ekwakhiweni. Lapho amakhasimende amaningi eza kithi ukuzoklama, ahlala ekuthola kunzima ukukhetha uphahla oluyisicaba noma uphahla olugobile. Lesi sihloko sizokwethula futhi sichaze cishe ukufana nomehluko phakathi kwalokhu okubili, ukuze ube nokuqonda okuyisisekelo lapho ukhetha.

Okokuqala, ake sixoxe ngokujwayelekile kophahla oluyisicaba nophahla olugobile.
Zombili ziyadingeka ukuthi zibe nezici zokuvikela amanzi nokushisa, futhi zombili zidinga ungqimba olungangeni manzi nongqimba lokuvikela ukushisa. Akukho ukusho ukuthi ukusebenza kophahla oluthambekele kungcono kunophahla oluyisicaba. Uphahla oluthambekele lusetshenziswa ezindaweni ezinemvula ngoba lunothambekele walo, okulula ukukhipha amanzi emvula ophahleni. Kodwa-ke, maqondana nesakhiwo esingangeni manzi, uphahla oluyisicaba nophahla oluthambekele kudinga izendlalelo ezimbili ezingangeni manzi. Uphahla oluyisicaba lungaba inhlanganisela yezinto eziboshwe nge-asphalt kanye nokugqoka okungangeni manzi. Ithayela lophahla oluthambekele ngokwalo liyisivikelo esingangeni manzi, futhi ungqimba olungangeni manzi lubekwe ngaphansi.
Ukusebenza kophahla olungangeni manzi kunqunywa kakhulu yizinto zokwakha nezakhiwo ezingangeni manzi, okungenakho ukuhlangana nokukhethwa kophahla oluyisicaba nophahla olugobile. Ungacabanga ngophahla oluyisicaba njengechibi elikhulu, kodwa inhloso yaleli chibi akukhona ukugcina amanzi, kodwa ukuvumela amanzi aphume ngokushesha ngepayipi elingaphansi. Ngenxa yokuthi umthambeka mncane, amandla okukhipha amanzi ophahla oluyisicaba awasheshi njengophahla olugobile. Ngakho-ke, uphahla oluyisicaba luvame ukusetshenziswa ezindaweni ezinemvula encane enyakatho.

Okwesibili, ake sixoxe ngomehluko phakathi kwalokhu okubili
Ngokuphathelene nokuhlukaniswa, uphahla oluyisicaba nophahla oluthambekele lungasetshenziswa ngezindlela eziningana ezahlukene, okuhlanganisa uphahla lokungenisa umoya, uphahla lokugcina amanzi, uphahla lokutshala, njll. Lezi zindlu zinqunywa ngokwesifunda nesimo sezulu sendlu. Isibonelo, uphahla lokungenisa umoya nophahla lokugcina amanzi luzokhethwa ezindaweni ezishisayo. Olokuqala luvumela umoya wangaphakathi kanye nokushintshana kokugeleza kwamanzi, kanti olokugcina lungadlala indima yokupholisa ngokomzimba. Ngenxa yezindawo ezahlukene ezithambekele, uphahla lokutshala nolokugcina amanzi luvame ukusetshenziswa ophahleni oluthambekele, kanti uphahla lokungenisa umoya lusetshenziswa kakhulu ophahleni oluthambekele.
Ngokuphathelene nezinga lesakhiwo, kunezinga elithe xaxa lophahla olugobile.
Izinga lesakhiwo sophahla oluyisicaba kusukela ophahleni kuya phezulu yileli: ipuleti lesakhiwo – ungqimba lokuvikela ukushisa – ungqimba lokulinganisa – ungqimba olungangeni manzi – ungqimba lokuhlukanisa – ungqimba oluvikelayo
Izinga lesakhiwo sophahla olugobile lisukela epuletini lesakhiwo lophahla kuya phezulu: ipuleti lesakhiwo – ungqimba lokushisa – ungqimba lokulinganisa – ungqimba olungangeni manzi – ungqimba lokubamba izinzipho – umugqa ongezansi – umugqa wokulenga amathayela – ithayela lophahla.

Ngokuphathelene nezinto zokwakha, ukukhethwa kwezinto zokwakha uphahla olugobile kungaphezu kophahla oluyisicaba. Ngokuyinhloko ngoba kunezinhlobo eziningi zezinto zokwakha amathayili manje. Kukhona amathayili amancane aluhlaza okwendabuko, amathayili acwebezelayo, amathayili ayisicaba (amathayili ase-Italy, amathayili aseJapane), amathayili e-asphalt njalo njalo. Ngakho-ke, kunendawo enkulu ekwakhiweni kombala nesimo sophahla olugobile. Uphahla oluyisicaba luvame ukuhlukaniswa ngophahla olufinyelelekayo nophahla olungafinyeleleki. Uphahla olufinyelelekayo luvame ukugandaywa nge-block surface course ukuvikela ungqimba olungangeni manzi ngezansi. Uphahla olungafinyeleleki lugandaywe ngqo ngodaka lukasimende.

Ngokuphathelene nomsebenzi, ukusebenziseka kophahla oluyisicaba kukhulu kunophahla oluthambekele. Lungasetshenziswa njengethala lokomisa. Lungasetshenziswa njengengadi yophahla kuhlanganiswe nezwe. Lungasetshenziswa futhi njengepulatifomu yokubuka ukuze ubone izintaba ezikude kanye nesibhakabhaka esigcwele izinkanyezi. Ngaphezu kwalokho, umbono wophahla awunakunqotshwa yilanga, okuyindawo engavamile yangaphandle.

Ngokuphathelene nokumodela komklamo we-facade, njenge-"Fifth Facade", inkululeko yokumodela yophahla olugobile ingaphezu kakhulu kophahla oluyisicaba. Kunezindlela eziningi zokuklama, njengokuqhubeka kophahla olugobile oluhlukene, inhlanganisela ehlanganisiwe, ukuvulwa kwe-peak okuhlanganisiwe, njll.
