Gypseous soil is characterized by complex and irregular behavior, so it is classified as problematic soil, which are mainly concentrated in arid and semi-arid regions of the world. As for Iraq, gypseous soils covers about (30–35) % of the total area of Iraq, as this type of soil is found in the Western Desert and extends to the southern parts of the country. Gypseous soils are considered strong soils, but they are subject to sudden collapse when wet. To control the collapse of gypseous soils, one of the most common types of geotextile fabrics used to strengthen soils is geotextiles. Shear and collapse tests were conducted for natural and reinforced soil with geotextiles, and it was found that increasing the number of layers of geotextile leads to an increase in shear parameters and reduces soil collapse. This study also tests the potential benefits of woven geotextile in increasing the ultimate bearing capacity of foundations based on gypseous soils. The foundation is built from a strong 10 mm thick steel plate measuring 100 × 100 mm. In this study are the depth of the geotextile layer, which was placed at depths (0.1B, 0.2B, 0.4B, 0.8B and B) of the width of the foundation used. The results of the experiments showed that soil reinforced with geotextile materials can help increase the bearing capacity and reduce settlement of gypseous soil, as it was found that placing the geotextile at a depth of (0.8B-B) is the best-chosen depths.
