Imiterere y'ibyumani imiterere igizwe nibikoresho byibyuma, nimwe mubwoko bwibanze bwubaka. Imiterere igizwe ahanini nibiti, inkingi zibyuma, imitsi yicyuma nibindi bikoresho bikozwe mubyuma byanditseho ibyuma. Ifata silanisation, fosifatiya ya manganese isukuye, gukaraba no gukama, gusya hamwe nubundi buryo bwo gukuraho ingese no kwirinda ingese. Ibigize cyangwa ibice mubisanzwe bihuzwa no gusudira, bolts cyangwa imirongo. Kubera uburemere bworoheje nubwubatsi bworoshye, ikoreshwa cyane mumazu manini yinganda, stade, hamwe n’ahantu hahanamye cyane. Imiterere yicyuma irashobora kwangirika. Mubisanzwe, ibyuma byubatswe bigomba gusuzugurwa, gusiga irangi cyangwa gusiga irangi, kandi bigahoraho.
