Umaleko wokugquma wemibhobho ukwabizwa ngokuba ngumaleko wokugquma wemibhobho eshushu, obhekiselele kubume bomaleko obusongelwe kumbhobho onokudlala indima yogcino lobushushu kunye nokugquma ubushushu.Umaleko wokugquma wemibhobho udla ngokuqulunqwa ngamaleko amathathu: umaleko wokugquma, umaleko okhuselayo, kunye nomaleko ongenamanzi.Akukho maleko angangeni manzi afunekayo kwimibhobho yangaphakathi.Umsebenzi oyintloko we-insulation layer kukunciphisa ukulahleka kobushushu, ngoko ke, kufuneka iqulunqwe ngezinto eziphathekayo ezinomgangatho ophantsi we-thermal conductivity.Umphandle ongaphandle umaleko wokugquma wenziwe ngokubanzi ngefayibha ye-asbestos kunye nomxube wesamente ukwenza iqokobhe le-asbestos sement yesamente umaleko okhuselayo, kwaye umsebenzi wayo kukukhusela umaleko wokugquma.Umphandle woluhlu olukhuselayo ngumaleko ongenamanzi ukukhusela umswakama ukuba ungangeni kwi-insulation layer.Umaleko wokungangeni manzi usoloko usenziwa ngeoli edityanisiweyo, iishiti lentsimbi okanye ilaphu leglasi elibrashiweyo.
Isakhiwo somaleko esibekwe kumda wombhobho onokudlala indima yogcino lobushushu kunye nokugqunywa kobushushu ngokubanzi siquka malungu alandelayo:
I-1) I-Anti-corrosion layer: Gcoba ipeyinti ye-anti-rust kabini kwindawo yangaphandle yombhobho;
2) I-thermal insulation layer: i-thermal insulation kunye ne-thermal insulation material layer;
3) Umaleko wobungqina bokufuma: ukukhusela ukufuma ekungeneni kwi-insulation layer, ngokuqhelekileyo isongelwe nge-linoleum, kwaye amajoyina agqunywe nge-asphalt mastic, edla ngokusetyenziselwa imibhobho ebandayo;
I-4) Uluhlu olukhuselayo: Ukukhusela umaleko we-insulation emonakalweni, ngokuqhelekileyo uhlanganiswe ngendwangu yeglasi phezu komgangatho we-intermittent layer;
5) Umaleko onemibala: Peyinta umbala ochaziweyo ngaphandle kwendawo ekhuselayo ukwahlula ulwelo kumbhobho.
Injongo yokufakelwa kwemibhobho yile:
I-1) Ukunciphisa ilahleko yokutshatyalaliswa kobushushu obuphakathi ukuhlangabezana noxinzelelo kunye nobushushu obufunwa yimveliso;
2) Ukuphucula iimeko zokusebenza kunye nococeko lokusingqongileyo;
3) Ukuthintela ukubola kwemibhobho kunye nokwandisa ubomi bayo benkonzo.
