Seraing pitfall to avoid

Polluted soils inherited from steel industry.

The former steel-industry basin left polluted soils on many plots. Before any signing, demand the soil quality certificate (BDES) issued by SPAQuE and the details of the remediation works carried out. Without this document, refuse the deed of sale — after-sale recourse is virtually impossible.
