Its a common mistake to give reinforcement for chajjas as normal beams in whcih the main bars are kept at bottom of bars. But chajjas are cantilevers and hence tension zone comes at top of the chajja.
And thats why, despite reinforcements ( which are given at bottom) chajjas develop cracks very soon because the tension zone is not properly protected by reinforcements. Correct method of providing reinforcement in chajjas is at top as shown in the video.
