Core Penetration Testing (CPT)

Braun Intertec uses in-situ testing to evaluate critical soil or rock properties for project sites on any type of terrain with Braun Intertec-owned instruments and drills. Our geotechnical engineers can evaluate geomaterial behavior in the field, which improves reliability and reduces uncertainty on project sites. Additionally, by performing in-situ testing to assess geomaterial properties, clients can realize significant savings simply due to more efficient use of our onsite testing and resources.
