Collapsibles porous sands are found to a large extent of Brazil, representing 5% of the country. In the layers of those soils the thickness are of to 15 meters. Precast-concrete piles were build, with instrumentation, made to that research. The piles were drive in soil sandy porous collapsible, found in the state of São Paulo (Brazil). Vertical static load tests were made in six piles (compression, uplift forces and horizontal loading). There were performed field tests and laboratory in samples obtained from the subsoil, aiming geotechnical characterization of the place.
