Geotechnical Engineering

The sub-surface conditions of a site play a critical role in successful project development. Unexpected conditions, such as shallow rock or sinkholes, can easily overwhelm a project schedule and budget. EAS’s geotechnical engineers have decades of real-world experience analyzing soil conditions and identifying potential problems early to help keep your projects on track.

We pride ourselves on delivering customized solutions to our clients problems. As an independently-owned firm, EAS engineers are empowered to approach every project site as unique and to deliver custom recommendations which address the site’s actual needs. EAS’s recommendations are designed to be relied upon throughout the entire project life cycle, not generic boilerplate to read once and discard.

Subsurface Explorations and Investigations

EAS partners with a trusted network of local, independent drillers to ensure that our solutions best fit the needs of the project and the client. Our drilling network has a wide variety of equipment, from truck- and ATV-mounted split-spoon rigs, to rock-coring equipment and advanced cone penetration testing devices. EAS engineers oversee the scope and layout of borings, and collect data in the most-relevant and most-efficient manner. Upon the completion of field work, samples are processed using our in-house, state-of-the-art AASHTO-accredited soil testing laboratory.

EAS’s geotechnical engineers and network of independent drillers ensure that your project sites receive comprehensive investigations you can build on.

Geotechnical Engineering Analysis and Design

EAS’s engineers have combined decades of experience providing site-specific, cost-effective strategies for each of our projects. We not only use industry standard processes and procedures, but also incorporate cutting-edge technology and practices where required.

Geophysical Surveys

EAS offers an array of geophysical survey options to include electrical resistivity, ground penetrating radar, and seismic refraction. Geophysical surveys allow for detailed subsurface information to be collected over large areas with minimal disturbance to the site.
