Recent studies in soil improvement have shown that the use of biopolymers are capable of significant enhancements to various engineering properties of the soil. Strengthening efficiencies, reduced permeability, and improvements to friction angle are all benefits that biopolymer use have onto the soil. However, in order to fully utilize the biopolymer technology into the fields, a full understanding of the geotechnical properties is necessary. In this study, one dimensional oedometer consolidation tests were performed with attached p and s wave sensors for elastic wave property measurements. Gellan gum biopolymer was used in this study, and its effects on the elastic properties and consolidation behavior for sandy and clayey soils were observed. Results showed that due to the high electrical sensitivity and hydrophilic properties of the biopolymers, the elastic properties and consolidation behavior of the biopolymer treated soils varied greatly from the untreated soils.
