 Civil engineering is a fast-growing application of geophysics. Here again, Sigma Geophysics is an established name in Canada and in several developing countries.

Specialized investigation fields include:
• Borehole geocamera
• Fractured rock detection using seismic refraction and resistivity
• Bedrock profile determination using Seismic Refraction
• Ground elastic parameters measurement using:
- Cross hole seismic
- MASW (Multichannel Analysis of Surface Waves)
•

Crosshole logging and velocity tomography
