Ukubonisa umlingani
Ukuphanda indlu nge-membrane yokulungiswa kwezikhukhula zezimpande ezikhulayo ngaphakathi kwezinto ezinye, isistimu se-bitumen esebenzisa ukulungiswa kwezikhukhula, kungcono kakhulu ukuphinda ukungena kwezindawo zezimpande zezityalo ezikhulayo kwehluzo yokulungiswa, futhi akusenziwa ukuthi kungabangela ukukhula kwezityalo, isimo se-material sekhulisa zikhukhula kuyisikhathi esiphambili. Kunezinto ezikhulayo zokulungiswa okuhle kakhulu futhi kungaphinda ukungena kwezityalo zezityalo. Isimo sokwenza kuyisimo esingcono ngokulinganayo leyo yokulungiswa yokulungiswa, isimo esiphakathi, kuyisimo esiyisimple, kuyisimo esiyisimple.
