Subsurface Exploration & Engineering

All structures rely on the ground for support. Subsurface conditions represent some of the highest risks to project performance. Exploration techniques such as drilling, geophysical surveys, cone penetrometer tests, and other advancements in investigation technology help quantify and reduce risk. 

We obtain data from subsurface investigations about underground soil and rock formations, groundwater, and mineral deposits help you make informed decisions for your construction projects, resource extraction, and environmental assessments. 

Braun Intertec offers a wide range of tools and extensive professional experience to evaluate the subsurface conditions for any project. Leveraging our in-house drilling crews’ expertise in obtaining subsurface soil, rock and groundwater information, our experienced geotechnical engineers evaluate their impact and provide design recommendations for your project.
