I-PVC ikhuphuke kakhulu ngoMsombuluko, kanti ukwehliswa kwenzalo ye-LPR yibhange eliphakathi kusiza ekunciphiseni izinga lenzalo yemali mboleko yokuthenga izindlu yabahlali kanye nezindleko zezimali zesikhathi esiphakathi neside zamabhizinisi, okwandisa ukuzethemba emakethe yezindlu. Muva nje, ngenxa yokulungiswa okujulile kanye nesimo sezulu esiphezulu esiqhubekayo sokushisa okuphezulu ezweni lonke, izifundazwe eziningi namadolobha angenise izinqubomgomo zokunciphisa amandla ezinkampanini ezisebenzisa amandla amaningi, okuholele ekunciphiseni kancane kancane kwesilinganiso sokuhlinzekwa kwe-PVC, kodwa uhlangothi lwesidingo nalo lubuthakathaka. Ngokombono wokusebenza okuphansi, isimo samanje ukuthuthuka akukuhle. Nakuba sekuzongena enkathini yesidingo esiphezulu, isidingo sasekhaya sikhuphuka kancane, futhi ezinye izindawo ziyekwa okwesikhashana ngenxa yokushisa okuphezulu. Ukuthuthuka kwesikhathi esifushane akwanele ukuletha ukulungiswa okwanele kwempahla. Njengamanje, isilinganiso sokuhlinzekwa kanye nesidingo se-PVC ngokwaso sisakhululekile. Ngesikhathi esifanayo, amanani kawoyela ongahluziwe kanye ne-calcium carbide abuthakathaka ngenxa yokukhululeka kwesilinganiso sokuhlinzekwa kanye nesidingo. Isidingo esibuthakathaka sibeka izindleko ezibuthakathaka, okwenza intengo ibe ngaphansi kwengcindezi ngezigaba. Ngenxa yokuthi inzuzo ephelele yamabhizinisi angaphandle okumba i-PVC igcina indawo yokulahlekelwa okukhulu. Isizini yokusetshenziswa okuphezulu isondela, ukwesekwa kwediski kusekhona, futhi intengo ingaqhubeka nokushintshashintsha ebangeni eliphansi, kodwa ayishintshi ukulindela komkhuba wokucindezela wesikhathi esiphakathi. Izinguquko ekufuneni esikhathini esifushane zizoba yinto ebalulekile ekuguqukeni kwentengo yesikhathi esiseduze, kugxilwe kakhulu ekuthuthukiseni isidingo.
