Sharing knowledge is part of our corporate culture. Our company was founded and is directed by professors, and we believe geotechnical engineering evolves through the exchange of knowledge, experience and information.
Each bulletin covers a single test or design decision in two pages, with reference standards and a source for every figure quoted. New editions are added here as they are published. Bulletins are written in Portuguese.
Two tests, two readings of the subsoil, and how to combine them.
Read the bulletin →When the undisturbed sample survives pushing, and when it does not.
In situ stiffness in Brazilian practice, from the blade to interpretation.
Papers by our team presented at conferences and in publications, from DMT in Brazilian soils to consolidation of soft soils. All available as PDF.
