Geology
Anddes provides geological prospecting services in support of engineering projects, applying regional and local geology techniques to geological and geotechnical subsurface investigations and geological modeling for lithological and structural characterization of geological formations.
Anddes also provides supervision services for geotechnical investigations, including detailed geological mapping, geodynamic and geomorphological assessments, logging in accordance with ASTM and ISRM standards, field testing, and geotechnical and geomechanical sampling.
