Our operational and technical teams are multidisciplinary and have expertise in underground prospecting. We offer various forms of geological/geotechnical sampling of soils and rocks, characterization and geotechnical tests of samples, subsidizing dredging and landslide projects, constructions and foundations, slope stability studies, correlation of geophysical methods, among other activities with the use of drills and special samplers.

Field surveys:

• Percussion probing (SPT)
• Rotary probing
• Mixed probing
• Auger
• Shelby
• Well inspection
• Vibracore
• Vane test
• CPTU
• GPR (Ground Penetrating Radar – Shallow Geophysics)

Laboratory tests:

After collection and storage, samples are transported to partner testing laboratories for laboratory testing, according to relevant procedures and technical standards (NBR).

• Complete granulometric analysis
• Atteberg indices
• Moisture content
• Maximum void index
• Minimum void index
• Specific weight of solids
• Natural specific weight
• Organic matter content
• Torvane test
• Special tests
• Triaxial
• Uniaxial

Offshore Probing

UMI SAN has equipment for onshore and offshore geotechnical surveys. The floats allow geotechnical soundings to be carried out in sheltered places, without the action of waves. For places with wave interference, we use Plael, a self-lifting platform for probing deeper areas (up to 15 m of water slide).
