Lateritic soils are predominant in tropical regions and widely distributed throughout the Brazilian territory. Their composition is characterized by a considerable presence of iron and aluminum oxides, which form cementitious bonds with soil particles. Recognizing the presence of these soils plays a fundamental role in foundation engineering, as omitting this characteristic when estimating load capacity can result in excessive costs in projects. Although the report from the Standard Penetration Test (SPT) plays a crucial role in foundation design, its accuracy in assessing the stiffness properties of lateritic soils may be limited. This research addresses this gap by collecting and analyzing data from various types of piles subjected to load tests in lateritic soils. The investigations cover experimental fields located in Campinas/SP and Londrina/PR, as well as cases in four satellite cities of the Federal District and an isolated case in Itaquera/SP. When comparing the estimated load capacity of the shaft with the measurements obtained from load tests, the results indicate that the shaft resistance of the piles in lateritic soils is approximately twice the values estimated by conventional Brazilian formulas. These results highlight the importance of determining the maximum shear modulus (G0) in profiles containing this type of soil, providing an understanding of soil stiffness and allowing for a more accurate and effective design of geotechnical projects.
