Asbestos and pollutant surveys in Aargau
In Aargau, checking the contaminated sites register can help prepare a project, but it does not cover every building material. A building survey remains a separate step.
We work throughout Switzerland. State your preferred language for discussions and the report when enquiring.
Describe my projectThe register does not list asbestos in buildings
The canton explains that its contaminated sites register concerns subsoil contamination. It is not an inventory of buildings containing asbestos, PCBs or heavy metals. A plot’s absence from the register therefore does not prove that its materials are free of pollutants.
Connect site history with planned work
Cantonal waste guidance distinguishes pollutants in materials from those resulting from industrial or craft use. This information helps plan investigations tailored to the areas actually affected by renovation or deconstruction.
Useful documents for an Aargau project
- Plans and construction year, with known alterations.
- Any existing building surveys or ground investigation reports.
- The history of activities and a list of elements to remove.
