Abstract Recently, an urban expansion prompted to construction of structures on weak or unsuitable ground soils. In a sustainable view, there is a need to investigate and improve such types of soils under consideration. Gypsum soil is one of the weak soils when exposed to wetness, especially the value of bearing capacity and Collapse. The main objective of this study is to carry out several model tests for gypsum soil at a relative density of 30% for dry and wet conditions under static vertical stress. The study involved evaluating the effectiveness of soil stabilization using geosynthetics reinforced (geotextile and E-glass fiber fabric) by using single, double, and triple layers placed at different locations. Soil with a gypsum content of 47% was used. Experimental tests were carried out on soil models for the dry and saturated conditions for a relative density of 30%. The ultimate bearing capacity was calculated, as well as the ratio of improvement BCR% according to the reinforcement layers. It was found that the ultimate bearing capacity increases 100% when using E-glass fiber fabric comparing used geotextile at reinforcement triple layers (0.25B+0.5B+1B) for dry state.
