Regulated by Brazilian Standard NBR-6484, the SPT-T Percussion Survey is recognized as the most cost-effective geotechnical investigative tool. It can be used to identify soil layers, collect samples, observe the water table status and assess soil consistency.

The equipment we use is constantly calibrated and our field services and torque measurements are continuously inspected as a standard procedure. The samples are kept in special recipients to ensure its quality during the transport from field to laboratory.

Our teams have the skills needed to work in sites with high safety demands, like refineries, ports, mining companies, and others.
