This paper presents the geotechnical characterization and properties of compressibility of soil residual Potengi Formation present in the city of Natal-RN. We run tests for geotechnical characterization and compression one-dimensional confined. The confined compression tests were performed in natural moisture in the saturated condition in a remolded sample prepared with the moisture content near the Liquid Limit and compacted in a sample with the energy of the Proctor Normal. They were testing inundated still in various stages of loading in order to analyze the collapsibility soil. The results showed that the soil has collapsed due to inundation to the levels of stress tested. It was also found that the deformation of collapse increases with the increase in stress of compression in which the soil was inundated and it has not been characterized a maximum of collapse.
