Geotechnical Engineering

Geotechnical Engineering is at the core of CVET, bridging the gap between geological and structural applications. Subsurface exploration allows for preliminary site characterization. We take pride in providing sensible and practical designs that meet the requirements of both our client and the property involved. With four in-house drilling rigs and two licensed well drillers on staff, CVET can provide SPT, CPT, DMT, and rock coring geotechnical drilling services as well as environmental drilling services. CVET is able to minimize overhead costs and provide a high level of customization to our clients. This allows for greater project flexibility, reduced fees, tailored data collection, and better project communication.
