2-D resistivity method has been used in association with Mackintosh probe and
Standard Penetration Test (SPT) to investigate the ground properties at Universiti
Sains Malaysia, Pulau Pinang. The purpose of this study was to determine the
resistivity value of the subsurface material together with N-value and M-value of
the particular location. The study also aimed to evaluate whether there is any
correlation could be made by the parameters measured. Borehole record
revealed that two types of soil exist up to 13 m; loose sand and stiff sandy silt. The
loose sand recorded N-value of 8 and M-value of 170 having resistivity value of 790
Ohm.m. On the other hand, stiff sandy silt recorded N-value of 9-11, M-value of
135-170 and showing resistivity value of 415-785 Ohm.m. The results showed no
clear relation between those geotechnical strength parameters with the resistivity
imaging result. It is due to non-existence of distinctive differences in the electrical
conductivity of the mentioned ground material when they are in the low strength
bracket. However, the resistivity result suggested the presence of higher resistance
material that is dry loose sand. The resistivity result was able to detect the water
saturated zone near the ground surface, which showed low N-value and M-value.
