The dynamic compaction method, very little spread in Argentina, has not been used in the city of Córdoba until this occasion. Its application in the “Bajo Grande Sewage Liquid Treatment Plant” has been a great technical and economic achievement. This article synthesizes geotechnical studies before the improvement, characterizes the dynamic compaction from the existing soil profile, and requirements of major works such as settlers and aeration tanks. Aspects of work control during its execution, data from soil studies after improvement, parameters of the mathematical model used to carry out the prognosis of seats according to the evaluated soil profile and measurements of validation of seats with the sedimentation tanks in operation are mentioned. Compaction was carried out by dropping a 10000 kg mass in free fall at a height of 15m from a crane, on points approximately 2.8 m apart. Two phases of several falls were executed allowing an increase in the relative density of the original soil to a maximum of 70%, reducing vertical settlements by 10%, decreasing angular distortion in half, doubling the bearing capacity, and reaching a maximum depth improvement near 6m. Then a ground leveling phase with mechanical compaction was carried out by project requirement. It could be concluded that the foundation of the construction with reinforced concrete stalls on the improved soil, presented a very superior technical-economic feasibility with respect to the alternative of a deep foundation with piles, which justified the execution of dynamic compaction in this work.
