Ubu buryo bugarura neza isahani yububiko hejuru yumwimerere kandi neza.
Nubwo ubu buryo bwo gusana ari intoki kandi bushingiye kubatekinisiye babimenyereye, ibisubizo byizewe cyane. Abatekinisiye babishoboye barashobora kumenya neza ahantu hahanamye hejuru ya granite no kuyikuraho neza, kugirango isahani igarure neza kandi neza.
