Ukuze kuphuculwe ukhuseleko lwesakhiwo, iHong Kong icacise iinkcukacha ezipheleleyo zenkqubo yokusetyenziswa kweiinqwaba zomhlaba ezigayiweyo: iimveliso ezinobukhulu be-zinc layer obuyi-≥ 85 μ m kwaye ngokuhambelana nemigangatho ye-GB/T 13912 kufuneka zikhethwe. Uphando lwe-geological kufuneka lwenziwe ngaphambi kokwakhiwa, kwaye abasebenzi abaqinisekisiweyo kufuneka basebenzise izixhobo ezikhethekileyo zokufakelwa okusemgangathweni, belawula ngokungqongqo ukuma nkqo kunye nobunzulu bokungcwaba. Emva kokufakwa, kuyimfuneko ukuba kwenziwe uvavanyo lokuxinana kunye nokucinezelwa kunye nokuqinisekiswa kozinzo lomlilo. Iimveliso ezingafanelekanga azivumelekanga ngokungqongqo ukuba zingene kwindawo ukuze kuthintelwe iingozi zokhuseleko ezivela kumthombo.

IHong Kong imisele indlela yolawulo yexesha elideiinqwaba zomhlaba ezigayiweyo, efuna ukuhlolwa rhoqo kweendawo eziveziweyo, ukwanda rhoqo emva kwemozulu embi, kunye nokulungiswa ngexesha elifanelekileyo komonakalo womhlwa kunye nowe-zinc layer. Kwangaxeshanye, misela ileja yokusetyenziswa, ucacise umda ophezulu wobomi benkonzo yeminyaka engama-30, kwaye ugunyazise ukutshintshwa kweenqwaba zomhlaba eziphelelwe lixesha okanye ezonakeleyo. Urhulumente uza kuqinisa nokuhlolwa okukhethekileyo kunye noqeqesho lwabasebenzi ukuze bandise iingenelo zabo ekuthinteleni ukugqwala, ukuthintela umlilo, kunye nokuzinza.
