Olayinka, L. A., Aremu Department of Physics, Ahmadu Bello University Zaria, Kaduna State, Nigeria. Corresponding author ABSTRACT Very Low-Frequency Electromagnetic (VLF carried out at the Ahmadu Bello University Phase II in order to investigate the suitability of the soil materials for the foundation of super Plus equipment and ABEM SAS 4000 were used for VLF acquisition respectively. The VLF interval of 10 m along each profile. The data collected from each of the VLF were processed and interpreted with the aid of Karous Electrical resistivity profile was laid on the weak zones revealed by the 2D VLF profiles through the aid of dipole and interpreted with the aid of Res2Dinv software. Borehole log of the study area was used as additional information which serves as a calibration tool. The 2D imaging profile of VLF-EM highly correlates with resistivity profile. The 2D VL revealed the conductive zone and resistive zones. These zones are suspected to be geological features (dyke, faults and fractures). zones was filled with an earth’s materials which are clay, and these materials are highly undesirable for the foundation of building structures due to its characteristics of swelling and contracting during rainy and dry season respectively. Thus, undesirable materials should suitable materials for the foundation of super should be avoided when the foundation of the structures is to be erected.
