As a geophysicist, I am dismayed by the lack of discussion in the geophysics forum.
There have been many advances in geophysics in the last number of years, with advances in equipment, research, and low cost of computing power.
We have conducted various geophysical projects for geotechnical clients, including:
- Investigation of extent of voids beneath concrete slabs
- Concrete integrity testing
- Pile Integrity Testing
- Pavement and Asphalt Thickness (Road GPR)
- Bridge Deck Investigations (Delamination/Deterioration mapping)
- Soil/Rock Stiffness profiling using SASW/MASW, crosshole seismic, VSP, and shear refraction
- Fracture detection and orientation mapping for joint set mapping of proposed open pit mines
This board (geophysics) has been pretty stagnant, with most discussion related to MASW.
I would like to try and open up this discussion forum with increased interest from geotechnical engineers with questions about how geophysics can help them with their specific problems.
There are a number of geophysical methods, including:
- MASW/SASW
- Seismic Methods
- Ground Penetrating Radar
- Electrical Resistiviy Methods
- Electromagnetic Methods
- Magnetic Methods
- Non Destructive Testing Methods
All of which have application to the geotechnical engineer and should be seen as another tool in your toolbox.
Please post in this forum if you have any questions about how geophysics can help with your specific problem, or help better approach a problem you often encounter. Post a problem and some information on the project and let the geophysics community see what we can do to provide you a solution that can help.
Thanks,
Christopher Phillips.

Hello Christopher, what is the main geotechnical and geological application of MASW? Can it record S adn P wave simultaneously?
Is it possible to do shallow on land Seismic Reflection and Refraction simultaneously?
Where can I find in internet firms that can do this type of job including Seismic Reflection on water?
