A foundation investigation was carried out at a proposed site for a residential building in Oda Town, Akure, Nigeria. The research is aimed at evaluating the competence of the sub-soil as foundation materials. Geophysical and geotechnical techniques were employed to characterise the subsurface foundation properties of the soil. A total of 8 Vertical Electrical Soundings and 6 disturbed soil samples were collected to aid the study. The geophysical results revealed three geo-electric sections, comprising the topsoil, weathered basement and rock head/basement. The topsoil is composed of compacted sandy-clay. The geo-electric sections further revealed the undulating nature of the rock head/basement. However, there is no evidence of faulting within the bedrock which can cause subsidence in the area. The geotechnical results revealed that the soil has a relatively low clay content. The soils within the study area are expected to exhibit low to medium swelling potential as deduced from the consistency tests. From these results, it can be conclusively stated that the subsoils within which the building or any engineering structure is to be founded are competent but generally, deeper foundations are recommended due to the prevailing H-curve across the vertical profiles for the soils examined.
