Abstract
Geoelectric resistivity method was employed to characterize the geo-materials at Ondo State University of Science and Technology (OSUSTECH) Okitipupa, Dahomey Basin, Nigeria, for suitability for foundation purposes. The methods involved Constant Separation Traversing (CST) using Wenner array and Vertical Electrical Sounding (VES) using Schlumberger array. The data obtained were processed with Ipi2win and excel software. The results showed that the subsurface structures were made up of lateritic topsoil with resistivity varying from 85 Ohm-m to 612 Ohm-m and thickness varying from 0.5 to 2.14 m; clayed sand with resistivity varying from 295 to 2,587 ohm-m and thickness vary from 0.67 to 3.4; clay with resistivity varying from 10 to 350 ohm-m and thickness varying from 3.8 to 26 m; and sand with resistivity ranging from 383 ohm-m to 59,707ohm-m. The clayed sand would have been the best layer to host the foundation because of its depth to the surface but it is generally less than 1.5 m and underlay by thick column of clay. The only competent layer that can host the foundation of high-rise building is the sand layer, therefore, the building foundation should be piled to the sand layer or pilling should be suspended within the thick column of clay.
