Ukubumba umjovo wedivayisi yezokwelapha kunikeza izinga eliphezulu, izingxenye ezinembile ezibalulekile embonini yezokunakekelwa kwempilo. Amasu ethu okubumba athuthukile aqinisekisa ukubambelela ngokuqinile ezindinganisweni zezokwelapha, iletha izingxenye eziqinile nezithembekile ezinamajiyometri ayinkimbinkimbi nokubekezelela okuqinile. Ilungele ukukhiqiza amathuluzi okuhlinza, amathuluzi okuxilonga, nezinye izisetshenziswa zezokwelapha, amasevisi ethu anikezela ngezixazululo ezenziwe ngokwezifiso ukuze zihlangabezane nezicaciso zakho eziqondile kuyilapho uqinisekisa ukuthobela imithetho yomkhakha. Xhumana nathi ukuze uthole izixazululo zokubumba izisetshenziswa zezokwelapha ezingochwepheshe.
