A construction method developed in early 1981 in Senegal, whose main objective is the evaluation of natural and human sources, specially those of wild vegetables and the phosphogypsum (a waste of chemical industry in Senegal). The introduction of the mechanical projection allows a noticeably growth in work performances and an improvement of the quality. The projection reduces de number of trades intervening in the work, doing away with plasters, watertightness systems and paintings, and simplifying the setting of technical installations and of carpentry. The acquisition of this projecting material is not very expensive, so, it is easy for small and medium enterprises to reach an expertness in gypsum work. Its finantial rentability is assured for a prize of the gypsum of 180% of the prize of the cement.
