Uphahla, njengoba negama liphakamisa, libhekisela ophahleni olwakhelwe imisebenzi yabasebenzi. Lolu hlobo lophahla luvame ukuba namandla aphezulu okuthwala futhi lungakwazi ukumelana nokuhamba kwabasebenzi, imibuthano kanye nemisebenzi. Umklamo ophahleni unaka kakhulu ezindaweni ezingashibiliki, ezingenamanzi nezishisayo ukuze kuqinisekiswe ukusetshenziswa okuphephile nokunethezekile. Ngaphezu kwalokho, uphahla lungabuye lufakwe uhlaza, izindawo zokungcebeleka, njll., ukuthuthukisa isipiliyoni esiphilayo. Ezakhiweni zezentengiselwano, uphahla luvame ukusetshenziswa njengendawo yokudlela evulekile, isiteji sokubuka noma indawo yomcimbi ukwandisa ukusebenza nokukhanga kwesakhiwo.

Uphahla oluvulekile lusetshenziselwa ikakhulukazi ukuvikela isakhiwo sokwakha emoyeni nasemvuleni, futhi ukuklama kwayo kugxile ekuphikisweni kwamanzi, ukushisa ukushisa nokuqina. Uphahla ngokuvamile alubhekwa njengezidingo zemisebenzi yabasebenzi, ngakho umthamo wokuthwala umthwalo uphansi, futhi awufaneleki ukuthi izisebenzi zihambe. Lolu hlobo lokufulela luthambekele kakhulu ezintweni ezikhanyayo nezimelana nesimo sezulu, njengamapuleti ensimbi, ama-asphalt shingles nokunye. Ukugcinwa kophahla oluvulekile kulula, ikakhulukazi kugxile ekuthembekeni kongqimba olungangeni manzi kanye nokuhlolwa okuvamile.

Okulandelayo yizici ezimbalwa ezibalulekile zokuqhathanisa phakathi kophahla olusebenzayo kanye nophahla olungahlali muntu:

Izici Uphahla hhayi uphahla

Umthamo ophezulu wokuthwala umthwalo, ulungele umsebenzi wabasebenzi abaphansi, awufanele ukuhamba kwezisebenzi

Idizayini igxile kokungasheleli, okungangeni manzi, ukuvikela ukushisa okungangeni manzi, ukwahlukanisa ukushisa, ukuqina

Ukukhethwa okubanzi kwezinto zokwakha, okugxile ekunethezekeni okungasindi, izinto ezimelana nesimo sezulu

Ubunzima bokulungisa buphezulu, ukuhlolwa okuvamile nokugcinwa kuphansi, ikakhulukazi kugxilwe kungqimba olungangeni manzi

Uma ukhetha uhlobo lwephahla, kuyadingeka ukucabangela ukusetshenziswa okuqondile, isabelomali kanye namandla okugcina isakhiwo. Nakuba ukutshalwa kwezimali kokuqala kuphezulu, kunganikeza abasebenzisi imisebenzi eyengeziwe nolwazi; Uphahla ngokuyinhloko lungokonga futhi luwusizo, futhi lufanele izakhiwo ezinezidingo eziphansi zomsebenzi wophahla.

Kungakhathaliseki ukuthi uphahla luhlala noma cha, ukuklama nokwakhiwa kwalo kufanele kulandele amakhodi okwakha afanele kanye nezindinganiso zokuqinisekisa ukuphepha nokuqina kwesakhiwo. Ekusetshenzisweni okungokoqobo, ukukhethwa kokufulela nakho kudinga ukucabangela izimo zezulu zendawo, isitayela sezakhiwo kanye nezidingo zomuntu ngamunye zabasebenzisi, ukuze kuzuzwe umphumela wokwakha ongcono kakhulu kanye nolwazi lokusebenzisa.
