This study is devoted to investigate the efficiency of granular pile anchor (GPA) in controlling heave of shallow foundations constructing over expansive soils. In this study heave measurements were made on laboratory model footings reinforced with GPAs having different diameter (3 cm. 4 cm and 5 cm) and embedded length (20 cm. 30 cm and 40 cm). https://parisnaturalfoodes.shop/product-category/florabear/
