Contaminated sites

Gain planning security

Determine pollutant situation

Are you planning a construction project or the acquisition of a property? Polluted sites present special challenges. First of all, the pollutant situation must be precisely determined.

Building owners are obliged to separate and dispose of contaminated material in accordance with regulations. We assess the environmental hazard and evaluate suitable measures with you.

With our comprehensive contaminated site consulting services, we contribute technical expertise, knowledge of public law procedures and legal aspects. Ecosens is a member of the specialist group of contaminated site consultants of arv Building Materials Recycling Switzerland.
