Developed from academic research and proven practices in the Oil & Gas industry, Sissterra is a non‑intrusive and rapidly deployable solution that delivers high‑resolution 3D imaging of subsurface conditions, enabling you to:
Strengthen geological models and better control geotechnical uncertainties
Improve the efficiency of underground works by anticipating constraints and adapting construction techniques in advance
Reduce soil treatment costs by accurately defining treatment zones and evaluating the effectiveness of ground improvement measures
“The interesting innovation provided by Sissterra lies in its passive technique and its speed of implementation on specific points. Using Sissterra gave us a better vision of the geology and allowed us to adjust our assumptions and therefore our excavation parameters. This successfully eliminated settling in the area.”

A turnkey solution for 3D underground imaging in restricted environments
Sissterra® is a unique passive seismic solution using ambient noise generated by human activity to image the subsoil and monitor dynamic changes beneath the surface. It ensures:
Optimisation of surface and underground work
Protection of the safety of property and persons
Facilitation of decision-making
Sissterra® reduces the number of boreholes and avoids active seismic sources – a real advantage when conducting investigations in dense and difficult to access areas.
A single point of contact for the entire value chain
Our experts master the entire value chain and can advise you at every stage:
Analysis of challenges and objectives, decisions regarding acquisition parameters
Data acquisition, processing, visualisation (2D and 3D) and analysis of results
Decision support (complete diagnostics, risk assessment and recommendations
How does Sissterra operate?
Sissterra® is based on the principle of correlation of ambient seismic noise (seismic interferometry).
This ambient noise, generated by surrounding human activities for instance, is captured using a dense network of autonomous geophones installed in the study area.
The large volume of data collected by these sensors, guaranteeing the technical robustness of the solution, is then transferred to our computing servers where it goes through a series of signal processing stages. With help from the resources of VINCI Construction’s R&D unit, these steps have been optimised from both a hardware and software perspective to obtain the best quality in the shortest possible time.
As an output, the solution makes it possible to offer 3D visualisation (seismic tomography) of the subsoil over a given period, as well as an ability to monitor changes to it over time (seismic monitoring) while keeping the acquisition device active.
“The initial deployment of the Sissterra® solution at the Grand Paris Express construction site has been a resounding success. This decision-making tool has helped us optimise our injection works and assess their impact, both quantitatively, through the increase in seismic speeds, and spatially, through the use of 3D visualisation. Ultimately, the solution enables us to manage the safety of our property and persons much more effectively and keep control of our budget in this type Location.”
