Conventional geophysics applications

Cavity (void) detection

Natural or anthropogenic cavity (void) detection by the most suitable geophysical method from the surface and in borehole.

 

Ground dynamic parameters

In borehole or Surface seismic measurement to obtain Vs30, VS, Vp and the dynamic elastic modulae of the subsurface such as Poisson’s ratio, Young’s modulus & Shear Modulus.

 

Geological model

Application of  2D or 3D geophysical methods to enrich an existing ground model (constructed by geotechnical parameters) with continuous data taking into account the heterogeneities of the subsurface.

 

Water leakage detection

Implementation of geophysical tracing solutions to detect underground water circulation and water leakage.

 

Hydrogeophysics

Upgrading of structural geology model (fault, position of stratigraphic layers, etc.) using geophysical methods (2D/3D) to detect and to optimise subsurface aquifers exploitation.

 

Diagnosis of earthworks (excavation and filling)

Application of geophysical imaging adapted to the problem (high performing, monitoring, etc.) to assess the geometry of the structure and its current condition.

 

Detection of Buried objects (structures & archaeological mapping) 

In borehole or surface geophysical methods to detect buried structures, foundations, tanks, etc.

 

Ground improvement

Geophysical measurement before and after injection process for a qualitative and quantitative evaluation of its effect.
