Abstract: Some geotechnical properties of soils around Eziobodo, Southeastern Nigeria was investigated using standard methods. Samples were obtained at three locations, Eziobodo, Ihiagwa and Obinze. The properties determined were particle size analysis, compaction (bulk density, dry density, natural moisture content, maximum dry density and optimum moisture content) and Atterberg limits (liquid limit, plastic limit and plasticity index). The sieve analysis shows that the samples are mainly sandy particles. The liquid limit values for the three locations (Eziobodo, Ihiagwa and Obinze) were 10, 46, and 47% respectively, while the plastic limit were 26, 21, 26.81 % respectively with plasticity index PI of -16, 25, and 20.19 % respectively. The natural moisture content of the samples were 10.3, 9.8 and 7.9% respectively. The bulk density values were 1.76, 1.69, and 1.66 mg/m3 respectively while the dry density values were 1.40, 1.35, and 1.31 mg/m3 respectively. The maximum dry density for the locations were 1.54, 1.43, and 1.41 mg/m3 while the values for the optimum moisture content were 24, 27.5 and 26.5% respectively. Because of their non-plastic behavior, high percentage of sand content, most of the sediments have low swelling potential; have high collapsibility potential, loses strength upon saturation and eventually susceptible to erosion.
