Fact 18 “For roofing in remote locations, lightweight concrete tiles can be fabricated using cement, sand and gravel; and optionally, locally available plant fibers such as jute, hemp, sisal, palm nut, coconut coir, kenaf, and wood pulp. Galvanized iron roofing and clay tiles are other alternative materials. Substitutes for asbestos-cement pipe include ductile iron pipe, high-density polyethylene pipe, and metal-wire-reinforced concrete pipes.” (CR, 2015; WBG, 2011; WHO, 2009)
