Help improve the income of a tribal community in Purok 7, Ginatilan, Kidapawan City by helping them make and sell hollowblocks. At present, they derive their meager income from getting sand and gravel from the river. Unoftunately, selling mere sand and gravel is not enough to provide for their basic needs. However, if they could add value to the sand and gravel by producing hollow blocks for construction, their income would significantly improve.
