ABSTRACT
A number of soil suction measuring devices were employed to measure total and matrix suction in-situ. Two sites were selected, each underlain by different subsoil and groundwater conditions. Measurements of suction were taken over a period of two years, from which it was established that none of the instruments yielded comparable values of absolute suction or suction change. The instruments did, however, record suctions that follow seasonal wet and dry cycles. The paper presents possible reasons for the disparity in measuments for the devices.
