Investigations of soil and groundwater contamination

Our services help to minimize expense risks before the beginning of the design and construction process. We always support you when you want to analyse the condition of soil and groundwater.


Our competence covers large-scale survey, restoration planning and supervision projects. We closely follow the development of new in-situ restoration techniques and plan cost-efficient restoration of the sites also taking into consideration customer preferences. 

We provide our services for industrial and real estate companies as well as public and private sectors.

Our services in groundwater and soil investigations cover all the phases from the history of the works previously carried out on the site to the present condition of the site including the methods for soil and groundwater restoration. Our experts have many years of extensive experience in the field of environmental technology.

In our work, we use the latest analysis equipment required for the field work.  We perform all necessary analyses either in our own accredited laboratory or in the laboratory of our partners. All our lab technicians are certified. 

Our services include:

  • history surveys of sites
  • investigations of the present site condition (investigations of soil, groundwater, sediment and gas in porous formations)
