Services

Our know-how and our mastery of applied geophysical methods mean that we are able to respond to all the problems connected with the geotechnical and civil engineering.

Characterisation of geological models

Particular geological horizons
Dynamic soil and rock models
Searches for materials, minerals
Aquifers
Faults and alteration and dissolution phenomena
Classification of sites based on seismic risk

Various determination processes

Dynamic parameters (Vs30, Young's modulus, etc.)
Rippability limits and associated earthworking methods
Dredgability
Auscultation and characterisation of the integrity of civil engineering structures
Subgrade and foundation depths

Research and diagnosis

Subsoil anomalies
Prior identification of anthropogenic cavities (marl pits, chalk caves, etc.) or natural cavities (karst phenomena, etc.)
Prior identification of buried structures and objects – industrial remains, tunnels, galleries, penstocks, foundations, basements, metal reinforcements, subsurface utilities, etc.
Prior identification of pollutants
Basic prior identification of contamination with explosives
Diagnosis of leaks in hydraulic structures – basins, dykes, dams, etc.
Archaeological search

Monitoring

Instrumentation linked to the geotechnical activity
Monitoring of leaks in structures
Monitoring of drought-related issues
Seismic monitoring on rock masses

Modelling

We use a wide range of 2D and 3D modelling and formatting software to model, correlate, synthesise (Res2Dinv, ERTLab, Surf Seis, SeisImager, PlotRefra, Reflex, etc.)
