This work presents results of the geotechnical characterization of an unsaturated residual mature soil of granite involved in a landslide which occurred in the city of Camaragibe situated in Pernambuco, Brazil. The geotechnical characterization of this material was performed including physical characterization, soil-water characteristic curve and shear strength (saturated and unsaturated condition). The soil-water characteristic curve was obtained through filter paper method, Haines Funnel and Richards pressure Chamber. The shear strength parameters were determined using direct shear tests (saturated condition) and direct shear tests with controlled suction, with suction varying from 0 - 500kPa (unsaturated condition). The results were discussed and compared with literature presenting satisfactory values.
