Why go to VALGO for the depollution of your soils?


Innovation :

VALGO has an internal laboratory in support of its field staff to validate innovative sites and soils’ remediation processes. The R&D laboratory carries out standard and custom feasibility pilots / tests:

  • In-house scientific structure active throughout the duration of the projects
  • Sampling, measurement and regular analysis
  • Services and advice to consultants and partners
  • CIR approved laboratory for the execution of pilots and tests
  • Validation of treatments and proposed thresholds allowing a commitment to results


Multidisciplinary business expertise:

VALGO has more than 40 specialized depollution engineers covering different disciplines (geology, geophysics, hydrogeology, microbiology, chemistry, process engineering …).

The skills of our teams cover the entire value chain of the revitalization of a polluted site, from the expertise of environmental audits, through the design of soil remediation works, until the client’s reception.

To complete its expertise, VALGO has set up a Geophysical Department in order to develop the application of this method to polluted sites and soils. This department can also perform pyrotechnic diagnosis.

On each project, VALGO promotes on site or in situ remediation techniques to reduce costs.
