Engineering Geophysics

We specialise in all near-surface Engineering and Environmental Geophysical methods and Data processing.

Our data processing style and results presentation exceeds the generic (typical) processing quality of average geophysicists, as we understand the intended engineering needs, and are able to offer high-end processing and interpretation of geophysics into relevant modulii parameters an engineer requires for loading design or site evaluation.
