dc.description.abstractGeo-electrical resistivity method was employed to characterize the geo-materials at Isheri, Lagos, Nigeria, for engineering foundation purposes. The methods involved vertical electrical sounding (VES) using Schlumberger array and constant separation traversing (CST) using dipole-dipole array. The results showed the subsurface to be made up of topsoil (clay/peat), clay, sandy clay and sand layers. The topsoil has resistivity values that vary from 16 to 92Ωm, the clay layer has resistivity values that range from 2 to 21Ωm, the sandy clay has resistivity values that vary from 34 to 39Ωm while the sandy layer has resistivity values that vary from 100 to724Ωm. The clay layer has depth values that range between 0.7 to 2.2m, sandy clay has depth values that vary from 5.5 to 23.6m while the sandy layer has depth values that vary from 7.3 to 35.7m. Based on of the resistivity contrasts coupled with borehole data, shallow foundation may not be feasible in the surveyed area owing to the presence of geological materials with low shear strength and a probable high volume of compressibility upon load application near the surface.en_US
