under shallow foundations in Sudan. The objective was achieved by conducting a laboratory testing program, several small scale field load tests, and analysis of data and results from all tests. Laboratory tests were conducted to determine the engineering properties of the in-situ soil layers. Small scale field tests consisted of testing in compression to failure.Three geopier elements and three pile foundations were conducted. Several theoretical methods were used to estimate the settlement and the ultimate bearing capacity of the footing on unreinforced soil. The analysis of Geopier resulted in 3.2 mm settlement and 553.86kN/m2ultimate bearing capacity, whereas theoretical values for footing resting on unreinforced soil were 11.28 mm and 212.19 kN/m2for settlement and ultimate bearing capacity, respectively. Several interpretation methods were used to evaluate the failure loads of Geopier and Pile foundations. De Beer’s method the most conservative methodwas used in the analysis. Geopiers acquired settlement and bearing capacity values greater than pile foundations. When Geopier gave 3.2 mm settlement and 553.86 kN/m2 bearing capacity, the pile gave 0.42 mm settlement and 350.14 kN/m2 bearing capacity.
