Porogarama igenewe kubara igisenge co hejuru: umubare w’ibikoresho vyo gusakara n’ivyo munsi y’igisenge, imbaho zo gupfuka n’ibipande vy’amabuye.
Ushobora kandi kubara ibipimo bimwebimwe vy’ingirakamaro vy’igisenge.
Ico giharuro kirerekana ubunini canke ubunini bw’ibikoresho vy’igice c’igisenge kandi mu bifunga ubunini canke ubunini bw’igisenge cose.
Kwitwararika! Igihe ubara ibikoresho vy'amabarabara (ondulin, amabuye y'agaciro canke amabuye y'agaciro) Zirikana ko iyo porogarama ibarura uburebure bw’igisenge.
Nk’akarorero, imirongo 2,8 incuro 7,7 ku murongo. Mu gihe c’ubwubatsi nyabwo, imirongo 3 irashirwaho.
Kugira ngo ubaze neza igitigiri c’ibipande vyo gusakara, urakeneye kugabanya uburebure bw’ibipande mu kubara gushika ubonye umubare wose w’imirongo.
Ntukibagire gushinga umubare w’ibintu bihurikiyeko neza (Bishobora kuba bitandukanye ku bikoresho bitandukanye - ukurikize impanuro z'abahinguzi).
Reka nongere ndabibutse ko mukeneye kugura ibikoresho vy’ubwubatsi bifise ububiko bw’imyanda.
