A simple method is proposed to estimate suction values in unsaturated soils ranging from 1,200 to 60,000 kPa in this paper using the conventional tensiometer results and the Kondner (1963) hyperbolic model. The proposed method uses the initial tangent value of suction versus time response in the suction range of 0 to 50 kPa for estimating the equilibration suction value. The model was tested on the published results of suction versus time response of high capacity tensiometers from the literature and an experimental program undertaken on compacted glacial till specimens with reasonably good results.
