In many civil engineering construction projects measures have to be taken to protect the environment. Examples are the research of existing pollution levels and the classification of soils to be excavated. In the latter case the purpose is often the assessment of the soil's possible reuse or the requirement for its sanitization.

For research in the environmental field and for the development of solutions for land sanitization, GeoConsult collaborates with consulting engineers Kuiper & Burger, Zoetermeer, who have an extensive and successful project record in environmental engineering.
