This work deals with the worthless leftovers of a disappearing industry in Basel and and transforms the highly contaminated ground into a visible and persistent body within the city.
Due to 150 years of production of chemicals such as paints, adhesives, solvents and later pharmaceutical products, unimaginable amounts of hazardous chemicals were released into the ground through open storages or leaking pipes. Approximately 10% of the processed soil accumulates as hazardous waste during the cleaning process and cannot be dumped in a regular landfill. Hence, these materials —the 10%— should not be taken out of Klybeck in Basel, au contraire, it should become experienceable and visible in the developing area. Therefore two new forms —a pit and a pile— are introduced to the area.
