Advanced Geophysical Services

A Unified Team for Subsurface Investigation

Advanced Geophysical Services (AGS) was formed through the acquisition of Advanced Geological Services by EPI Geophysics, bringing together two highly respected subsurface firms into one unified geophysical company.

Advanced Geophysical Services brings over 30 years of experience delivering advanced geophysical investigations and subsurface characterization. EPI Geophysics complements this foundation with a strong reputation in Ground Penetrating Radar (GPR) and private utility locating. Together, these strengths create a well-rounded, full-service geophysical team capable of supporting projects from initial site assessments to well beyond project completion.

This acquisition expands our technical capabilities, staffing depth, and geographic reach, while maintaining the same trusted personnel, equipment, and client-first approach both companies are known for. Clients continue working with familiar faces, now supported by an expanded team of licensed Professional Geologists and experienced geophysicists.

AGS also continues its long-standing partnership with Environmental Probing Investigations, providing seamless, in-house geophysical support for environmental and geotechnical drilling projects to provide fully integrated subsurface solutions.

The result is a stronger and more versatile company. Offering broader expertise, increased capacity, and enhanced value - while preserving the reliability, responsiveness, and relationships our clients trust.

Thank you for bearing with us as we continue to update and refine our website!

Subsurface Insight for Confident Planning

We provide non-intrusive subsurface investigation services that support environmental and engineering teams by identifying utilities, characterizing site conditions, and helping clients understand the full picture of what lies beneath the surface.

How We Help Reduce Risk

Early subsurface insight helps identify underground utilities and unknown conditions before drilling or excavation begins, reducing the risk of strikes, delays, and costly changes.

IDENTIFY HIDDEN UTILITIES

Understanding subsurface conditions upfront allows teams to design targeted drilling and sampling programs that improve efficiency and reduce unnecessary disturbance.

PLAN TARGETED INVESTIGATIONS

By identifying subsurface conditions early, we help clients avoid costly surprises, delays, and rework later in the project lifecycle.
